In this video, we look at photosynthesis. We start by looking at the word equation and then the formulas of all the molecules involved. We then explore the idea of limiting factors.

Love how this guy has become a celeb by saving everyone’s GCSEs
At this point everyone knows this man.
in the uk at least xd
I hated this man throughout the year, but as it has come to the end n me watching like all of them he’s actually like taught me all the stuff. So I longer despise him. But have respect
He’s underrated
fr i have a bio test in like 10 minutes
Your back must hurt from carrying the grades of every single student
Exactly how is this guy still standing up straight?
@@makariousaziz3565 Because the grades are falling off his back.
Hes too worthy, this guy is shaking the grades off and giving it back to us.
What a legend.
Ikr
Faxx
Literally better than all my science teachers combined
This man teaches whole topics in 5 minutes while teachers take a whole hour to teach this. WHAT A BEAST! #THEGOAT
so true
Hi, didn't get the chance to thank you for saving my science gcse last year. I got B's and C's after getting E's in my mocks. Overall C in science gcse. Got into the college and course I want!
If ur in year 11 i recommend just taking notes in a book as u watch the vid, unfortunately i started revising 1 week before my gcses so he came in clutch ;) good luck with ur gcses
would you advise flashcards? that's currently what i'm doing.. i'm in year 11 and revising early as well as my mocks in 2 weeks. What would you recommend?
You just motivated me after getting e's for my mocks
H Mo well done
H Mo yikes, my exam is in 10 days. Wish I started revising earlier.
bruh, exams are tomorrow and im cramming and aiming for a 9 lol
got test tomorrow. Thanks for allowing me not to fail (hopefully)

Just imagine if he was teaching maths too!
all schools would shut down , they'll be useless
His brother probably does
@@Matthew-wv8eo lmao frrr
The world will be saved

good luck
you deserve 1 million subscriber's
He has more than that
The people who disliked this video are probably the teachers who have taught the topic worse than this guy
i have a combined science (higher) mock exam tomorrow, and this is helping so much, and i would just like to say thank you sir for being such an amazing teacher, i will not fail thanks to this. Once again, THANK YOU. you don’t understand the amount of people you’re saving and helping right now.
This guy is a better teacher than my own

I am
I'm trying but I'm so not motivated like 36 days until our first exam and I've got so much revision omg like idk where to start
Finally my GCSEs are tomorrow so I must say thank you to this national treasure. Helped me more than any science teacher ever could.
what did u get,you dont have to tell me :)???
Love how he teaches us what our teachers have failed to do
This man being the reason half of the population pass science
I’ve got my biology exam tomorrow 😭the day has finally come. Good luck to everyone out there!
Thanks, I got full marks on my end of topic exam because of this!!!
Thanks for saving all gcse students, we love youuu
Wanna thank this hero for saving my GCSEs. Doing in 5 minutes for FREE what teachers couldn’t do in an hour.
If your GCSEs coming up don’t be stressed, just keep at it. Make notes from his videos cause trust it saves you. Thankyou free science lessons
guy is my g, and he dont even know it
got a 9 in all my sciences cos of this man I would watch every single vid and pause to write out notes thanks for everything class of 2023 out see you when I'm doing my Alvls
The respect I have for you go up and up everyday sir. I can’t even get this much knowledge through a payed private tutor. You are an absolute absolute legend and we don’t deserve to have u. Thanks you sooo much
This man officially just saved my GCSE's
this guy has become a celeb by saving everyone’s GCSEs
You are the only hope for my son passing science. If he gets a pass mark, I'm sending you a gift.
At last I hit a channel with accurate explanations and PROPER ENGLISH PRONUNCIATION. Thaaaaaaanks!!!!
Yes. Nowadays it would be an annoying American-sounding AI bot. ;-)
This man is a world hero , i showed my teacher and now we even use him in assembly's
Thank you so much for these videos they are saving my science GCSEs
Ive only just found out about this guy and my bio gcse exam is in 4 days, wish me luck
Good luck
We dont need teachers. We need you. who else is here for year 11 mocks 😂

Can I give this guy a hug ?
Thankyou so much, I got a 7 in my mocks from just watching Your videos😊

i love this dudes videos its short simple and straight to the point
Love him so much,I've spent hours and hours and days and months and YEARS learning stuff and didn't get it and I randomly found his channel and I was saved,3-7 min videos clearing every thing.Oh my God,LITERAL LEGEND
True GOAT- 5 mins in what takes 1 hour for most 🎉
in my school, there was a petition to get him to become our teacher... sadly it didn’t happen 😂
I’m here because of corona virus =/
same
I'm still here because of CoronaVirus =/
Freesciencelessons thank you so much for the videos. I got 7s for separate science and this wouldn’t have happened without your help. I am looking forward to seeing more of your a level content 👍🏻👍🏻
Thanks for the comment and congratulations on your grades. I'm happy to have helped.
@@Freesciencelessons Your welcome! Also I took Chemistry and Biology for A-levels. Biology is AQA and chemistry is edexcel. Does your A-level videos complement the following exam boards I mentioned?
You just got a sub cause I am in y9 and struggling in science so this helps me quite a bit. Science isn't my best subject but I in set 1 and I want to keep it that way. for some reason i cant always find the motivation to get better although deep down I really do want to. If anyone has any tips or stories anything would really help me figure out what to do because I really stuck and whether I like it or not, one day I am gonna regret not revising hard enough and wishing a redo all over again. It seems stupid to say so and not do anything but I just don't know how to start. Pls reply someone!!!
You have a great mindset, don't go too hard on revising in year 9. But in Year 10 revise alot, to get ahead of everyone so you can have a great future
Ahhh biology today! HELP MEEEE LORDDDD. Wish me luck please. Best of luck everyone
This is the best when you know the information and it's just repeated in your brain 👏🏽✨🙏🏾💕🇱🇨
Ive got an exam tommorow :(
Same
same
Thankyou you are amazing at explaining, you are helping a lot of people with what you do
Abigail Thomson hey 👋🏾
Exam starts later, gonna watch as many of your biology vids as I can!!
I'm a mature student embarking on Biology GCSE. These videos are immensely helpful. Thank you.
Thanks for your comment. I hope that you enjoy your Biology journey as a mature student and I'm glad that my videos are helping.
I have a test tomorrow about this....
I'm dead.
You too? Same, good luck on your test
I’m in year 8 but I have a test on it soon!! :(
i am in year 10 and i have a test on it tomorrow
same
im yr11 and have mocks my current grade is an A (grade 7)
I have an exam in 2 hours, this is really helping
Hello sir, could you please do A-level biology and chemistry videos as well, your videos are very helpful
exam tommorow this guy is a saviour
Hi Shawn, may I know what the turning point of the line is called? 4:35
Sir you are a legend
You deserve about 100 million subs.
Mocks tommorow and GCSEs next year, so il probably be seeing u next year too
thank so sir, saving everyones gcses
mocks tomorrow wish me luck
once a legend always a legend...
You acctually make me understand science
the greatest video ever. this is better than ali a :D
Thanks so much, I’ve been clueless on this for ages and you’ve cleared this up :) u deserve more subscribers
Does he have a video on plant tropisms...I think we need to know that for Bio Triple
see what the specification says instead
Biology today!! Tysm for this!
I absolutely love you. You’re really helping me catch up despite my low attendance in previous years. Thank you🫶
Thank you sir for the videos. I got 7-7. Now I am doing A level biology !!!
God bless this man
THANK YOU ! you are saving my life .
Such a clear explanation, no fiddling around the subject like other videos. So helpful you saved my life on many occasions aha
thank you sir u got me an 8 in biology when i thought i was gonna fail ur lit so amazing thank u so muchhhhh
Sir you honestly are a legend and are helping everyone so much. I swear the only thing my teacher taught me from this vid was the photosynthesis equation
I’m not doing GCSE, I’m having an end of year test for y7 in science. Hoping this will save me, the test is tomorrow. I’ve done no revision. It’s been out for more than a week.
if anyone wants the balanced equation it’s:
6CO(tiny 2) + 6H(tiny 2)O -> C(tiny 6)H(tiny 12)O(tiny 6) + 6O(tiny 2)
if you hold down the number it should give you the small number like ² or ⁵
how does he fit so much useful info into such short vidoes
I legit revise from those videos
do your videos cover all the similar topics between all exam boards meaning that it would likely to exclude some topics from my exam board?
Ryhan Ahmed I think he focuses on the AQA syllabus but I’m not entirely sure.
Just wondering, does it matter if you write the balanced equation in the exam rather than the none balanced equation?
murkybiscuit1 yes you will lose marks
I don't think you'd be penalised for writing the balanced equation.
Writing a balanced equation is better, as it's more accurate. I would recommend the balanced equation, always. (Science Teacher)
i have an end of unit test on bioenergetics tmrw n ill probs get the results after the christmas holidays. ill update n say what i got!!!
i think he explain much more better than the teachers in sc
got this exam today, thanks for the good grades
Im watching this before my mock exam today lol
did u pass 💀
Is there a biology paper 2 section? I can't seem to find it. Many thanks.
Yes but there are only five videos so far. Seven more will be uploaded this weekend.

I'm in Year 9 I think Same grade?
What of light independent photosynthesis?
Will you be uploading videos for the biology paper 2? With topics such as homeostasis & response? Thanks so much your videos have been so helpful!
Yes I'll be uploading Physics 2 in January and then move on to Biology 2 before the exams.
Freesciencelessons Cool thank you
tomorrow:(((
good luck man
Ez
We got thisss!!😊
Good luck guys
Man I just want to hug you
Amazing Video I’m in year 7 and still understood it very clearly explained
hows year 11 mate
Thanks so much. very helpful video
When carbon dioxide and light intensity are the limiting factors, are they directly proportional to the rate of photosynthesis?
Do we have to learn the structure of a leaf?
His tie is lit ngl
