You alone made me understand in 4 minutes 20 seconds what tens of teachers through out my school & colllege could not. Before today I used to think of myself as dumb but now I know who is.
Thank you for taking time to write this comment! It means a lot to me to hear that this style of explanation is working!😊 I've had a similar experience throughout my education and that's why I'm trying to do it differently!
I agree
It's crazy to me you had 10 different teachers trying to teach you this topic! I didn't even have one. Jokes aside, I agree. It's a really great video!
Wait till you find out about ferns!
No need to be hateful
I went out a few years ago collecting Pine Cones in a plastic bag. When I got them home I put them all into the sink to wash all the dirt off. They quickly closed up so I left them on a window sill and after about a week the Pine Cones had started to open back up. And yes there will be very small seeds inside the Pine Cone.
How long do they take to close up in water?
I've watched 4 different explanations of this and yours is by far the best. Well done.
I am very happy to hear that! Thank you, Jeff :)
Absolutely agree that you taught in less than 5 minutes what I should have learned decades ago. Nature is awesome if we would only look and listen.
Thank you. Marvelous
Thank you for your wonderful feedback! :)
North Carolina. So amazing. Gold dust everywhere.
One of the best explanations by far.... just need the extra details about megaspores gametophytes and such
After searching through countless websites and videos, FINALLY finally, this one satisfied my curiosity about the parts of the pine tree. Thank you!
That's wonderful to hear! 😊
I feel my nose getting “pregnant” watching this 😅 but our pollen is bad but I never seen it like this
Great video! Really clear and informative. I was wondering how open the female cones are at the time of pollination and this explained it really well. I am subscribing!
I'm so happy to hear this video answered your question! :) Thank you for your support!
I am here due to a neighbor who wants his trees to be cut down they were in my childhood. Yeah I get with injuries but not the healthy ones. So I am on a small mission to find small pine trees or seeds that I can let my backyard to take off.
Nature is indeed, very beautiful.! "Long live nature, then...!!!"❤😉

Wow what an amazing breakdown, I smashed the subscribe button so quick! It’s learnin time!
Thank you! ❤
This is incredibly fascinating and informative. Thank you!
Thank you, Sophia! :)
Thanks !
Seriously dude Amazing work wow u are blessed with thousands of students who are happier after seeing this video of yours
Please keep uploading videos related to botany 🙏❤️
Greetings! Great! Thank you! 🥰
This video helped me understand without long grammars that my textbooks have been giving me thanks.
Is there a certain time of year to try this experiment? How long did it take for yours to close when submerged?
Hi, Chelsea! Any time of the year when you can find the cones on the ground is good. When it's been dry for a few days, you'll get nicely opened cones (make sure you're picking up mature cones). It usually takes about a couple of hours or more for the cone to close, but each cone is little different, depending on its size, age, etc. Let me know how your experiment goes, if you try it! :)
nice
Why is this not taught in elementary school?
Because they wouldn't understand, that's why you needed this video
@@pogchamp8417thank u for this comment.
This is a great video to learn about nudibranch plant fertilization. Masha Allah. From Bangladesh 🇧🇩
Amazing video mate!! You just made my day...Keep up the amazing work!
Wonderful to hear! Thank you! 🤗
Thank you for sharing your video! I teach an online class for Biology 2, and after I discuss the Pine Life Cycle with textbook images, I really wanted to show my students the actual pine pollen cones and ovulate cones. So I appreciate you showing those burst of clouds of pollen! I actually did do your experiment with the pine cones I had picked up from a camping trip a few years ago (I use them as decorations). I can't believe it still works with old pine cones! I left the cone in water for about an hour or so, it closed up to almost 1/3 of its size! It made my day. As a scientist and biologist, nothing beats doing a simple cool experiment! I appreciate it!
Very informative....
tq u very very much
Awesome. Thanks for the coold video. Do you know how long can the female cone be in the tree? And, during that time, the female cone opens and closes constantly?
Epic man. I'm wondering now about germination process and methods, cold stratification, plus the difference between seeds and nuts after finding a big cone in California by point dume with nuts instead of seeds I think.
Hi Chris! Although majority of pines have winged seeds, seeds of some species are large and not winged and you might think of them as nuts. Inside of the hard shell of these nuts is a seed. One good example would be pinyon pine. These types of seeds rely on animal dispersal, rather than wind.
Seed stratification and germination is a great topic and I'll be talking about it in a video I'm preparing for this spring. Stay tuned! :)
@@natureclearly I'm that animal then haha I found a huge cone in California then happened to knock some nuts out. Trying to germinate them now but it seems like nothing's happening in the wet paper towel. Cant wait! You know your stuff thank you
We have several large Podersosa on our property and this year was the first time in 35 years that I have seen seeds ddrift in the wind. We had several squirels that decided to decimate the trees of cones and thereby releasing the seeds. I have gathered up some of the seeds and wonder if I can get them to grow.
Oh, So all these Lil yellow clouds floating around like crazy really isn't spirits coming to posses us? this is wonderful news. just wait until she gets home. She had me terrified n horrified
love you bro
Thank you so much , this video very useful for understand pine's reproduction. keep rocking
Thank you! I am happy it's helpful for you! :)
Nice video with explanation sir , any one easily understand the mechanism 🙏 thank you
Very educational. Thank you and please go on with this👍🏽
Thank you! ❤
Great video! Do you have a reference for why the cones close when wet? I thought it had to do with wind and wet cones cant fly.
Thank you! Beautifully expalined!
It's good to know that they aren't live mutant larvae here to take over our minds 😭
So where pine nuts come from
Pine nuts are unshelled pine seeds and there are multiple pine species that are used for pine nuts production!
4:00 this thing looks HUGE
It is! This cone comes from a Coulter pine, the heaviest of any pine tree!
wow what a lovely explanation. Thank you
this is excellent, thank you!
Nice content sir next time I suggest can you explain about physiological process of plants😅
Thank you! :) What topic are you interested in?
I grew 5 conifer species at home from cone seeds, including 3 species of pine.
That's cool! How big are they now?
@@natureclearly Only 2 have survived... 1 larch about 2 or 3 feet tall. 1 Siberian pine around 3 or 4 inches tall. I knew Siberian pines were very slow growers. But... Like literally 1 cm a year... I heard the reason is that in nature they grow in extreme cold where summers are very short, so they are careful not to fall victim to sudden early or late frosts.
thanks for the video I learned and I sneezed
Very cool! Thank you for this.
Fascinating! Thank you.
Beautifully explained
Thank you!
It's confusing I think to describe the male structure as a "cone". When I learned taxonomy in school the male structure of a White Pine was called a catkin. Other woody plants have catkins as well, like Birch. Maybe the words are interchangeable. Maybe I'm just splitting hairs. Cheers from Tucson Arizona.
If you dive deep into details, male and female cones of _some_ Gymnosperms are not the same. While male cone is a strobilus (a stalk with scales on it), the female cone is a constrobilus (basically the strobilus but with another strobila instead of scales). Female cones also have 2 kinds of scales which have different origination, while male cones have only one type of scales. Anyway, it is absolutely correct to say that Gymnosperms have male and female cones.
@@fainabikmurzina2646 wow...that's pretty technical but I'm such a plant nerd I enjoyed reading. Can I bore you with a short story? While doing some landscaping years ago I made a $1000 wager with a guy who worked with me that he couldn't tell me the correct name of the female fruiting structure on southern magnolia. As you know its a beautiful ornament on Southern Magnolias mostly north of Florida. He spent a week, he called the Pennsylvania Horticultural Society, ( I never saw that coming) he read everything he could find and threw his hands up when all he came up with was "cone". Maybe I set the bar too high. The name i learned was gynoecium from Michael Dirr's manual, but because his efforts impressed me I paid him half. His wife had just had a baby girl.
Wonderful video! So very well presented and explained! Thank you!
Thank you very much! 🥰
Excellent explanation! Thanks.
Thank you! :)
Absolute lifesaver love you
Wow, very interesting
Merci les explications sont excellentes 😊
Thats a great video ;knowledge quite enhanced ,thanx .
Wonderful to hear! 🤗
Yee I trier today
الله يعطيك ألف عافية
Great content !
thanks so much for this! i learned so much!
That's so great to hear! 🤗
How seeds 'choose' when to sprout would be nice and informative addition.
must be in florida? awesome video. how the heck does the pollen find its way into those microscopic holes, is that how it selects for genetics or just a reality of being completely protective?
Aren't those same trees easily catches fire because of the oil in them I remember we use to use it to catch fire u don't need no paper or anything because it already have its oil in it to blaze
wow thanks
Well explained thank u sir for this video.
Thank u... for clearing my doubt
This is gold
This is sooo cool.
Ótimo vídeo! Faço faculdade de Biologia e esse vídeo conseguiu tirar as minhas dúvidas, mostrando o mecanismo em organismos reais. Vou me inscrever no canal!
That was beautifully explained! Thank you! (new subscriber, VA)
Thank you! ❤
I have a question ⁉️ Actually two. Once a female cone is pollinated, is the whole tree thus pollinated? Does the pollen need to find a female cone every year or once pollinated, the tree produces seeds for the rest of its life?
Oh! and can a trees male pollen pollinate it's own female cones? So many questions!!!!!
You can think of every cone as a separate "unit". Every cone needs to get pollinated separately and on one tree, you can find cones at different life stages. New cones are produced every year and to produce seeds, they need to get pollinated by pollen from "fresh" male cones. Does this answer your question?
Yes! It can happen, but pine trees have a way to avoid (or at least minimize) self pollination. Male cones grow mainly on the lower part of the tree, whereas female cones grow higher up. That way, when the pollen blows in the wind, it goes away from the tree, not reaching the female cones on the same tree. Next time you see a pine tree, take a look if you notice the female cones clustered higher up in the tree! 😉
WHAAATT. I’m literally in my senior year and I never knew this about pine cones 😂😂 I used to play with pine cones all the time as a kid and I’ve seen all of these stages and types, even the seeds! But I never realized the amazing cycle that was happening! Praise the Lord for His incredible creation!
So impressed with the explanation that i subscribed .
Thank you.
I'm happy to hear that! Thank you :)
this video is wonderful! i don't know how many times i said "ooo wow" while watching! ahahhaha really facinating! thank you
That's so great to hear! Thank you! 🤗
I am a Waldorf Teacher and this video was very useful to me.
That's great to hear! ❤
WOW, this is well explained, but can you please the explain the process in full details?
Thank you! What part of the process would you like to know in more detail?
Very nice explanation.
thanks man it really cleared my years of confusion
!
I'm very happy to hear that! 🤗
Very good information and visuals, I learned something and have more appreciate the pollen, that I’m allergic to, 🤧.
Thank you, Andrea! :) I'm sorry about your allergies. Do you live in an area with many pine trees? Here in California, we are almost at the peak of pine pollen season! 😬
@@natureclearly Yes, Berkeley!
excellent video. i learned this a couple months ago at college
Thank you!
Thanks. This is such a complete and clear video. In addition it’s interesting and educational.
Thank you! :)
Thanks this is helpful in bsc 1st year
That's great to hear! :)
Is there a way to harvest seeds from the black hills spruce ? Education needed
Are you able to harvest the cones of the tree? If so, I recommend harvesting mature cones when they are closed (when it is moist outside), then taking them home and placing them into a paper bag. Once the cones are dry, they will open and release the seeds. Let me know how that goes! :)
@@natureclearly got it except I want you to explain when is the cone mature. No sap or green color but before they open up much n moist out ?
@@natureclearly I did try ur technique with some last year’s still hanging n I did get some.
@@scottwebber652 You're right, the cone should not be green, that would be too early for harvesting seeds. I've had the biggest success harvesting seeds from cones that are mostly closed but slightly open at places (check out the video at 3:50, the cones showed there were bursting with seeds!). To have some comparison, the closed cone shown in the video at 3:57 never opened! You need to get it just right and that might take some guessing and multiple cones!
Thanks
Wow make more videos
More videos coming soon!
❤️❤️❤️❤️
Very awesome explanation
Thank you! :) I hope it helped!
@@natureclearly ofcourse it is very informative and well explained 😊😊
I’m so confused is a pine tree considered transgender you said it has male and female parts on the same tree is a pine tree man made
