I am preparing for premedical exam here in India....Your videos are really helpful especially the modern physics part and periodicity !!! Thanks for your work ! Awesome teaching✌👌 Waiting for your videos on Ecology ..professor Dave😊
Thanks for these wonderful videos. I find my learning is best aided by multiple angles of explanation and your videos are often the ding ding ding I needed to comprehend ideas! You’ve been so important to my understanding of biology and I’ll always be grateful to your team!
Great series, Professor Dave. Learning a lot! The progression method you've established here makes it much easier to digest and understand plant evolution. Thanks, and keep up the great work!
I study for 30 yrs. Just to reproduce this ferns I have known that birdsnest has pores at the back of Thier leaves but then I find it since I don't have the equipment plus the knowhow to do it And I was able to reproduce by taking the baby plants that grows around our sorrounding specially in the coconut tree That is my source of my seedling And let it grow in the owns roots what is hard to wait for 30 yrs to have a mother plant In which I was lucky enough to have a 6 mother plant as source of my nedium
How different are the ferns we have now compared to the earliest ones? Have they remained mostly unchanged? If not whats the oldest plant species on earth now that has changed the least?

Psilopsida are first vascular plant?
Thank you for this !!!!
Lycopodiopsida developed roots and stems before Polypodiopsida 👀
Great! So, now what?

Nice video. I am father frond of ferns.
“father” was supposed to be “rather”, oh well....
Are ferns family with bryophytes
No
Why can't my professors teach like this...
3. The sperm cells in ferm plant require water for fertilization How does the fem plant
reproduce when water is unavailable to it?
It doesn't
Without water turger pressure is not maintained and the cells as a whole shrivel up and die. Osmosis needs to occur in order for life to exist.
Ferns require water to enable the movement of the sperm to reach the egg. soooo... yea it does'nt.
The plant has sex
