In this video, we look at the sizes of cells. We explore the meaning of the words millimetre, micrometre and nanometre and how these relate to cells and the objects within cells.

Thank you! I literally sat through 3 hours of biology class and came home to randomly stumble across your videos! 15 minutes of your videos taught me what the prof could not, so THANK YOU!
I was a volunteer at RSPCA Radcliffe Animal Shelter. I am a volunteer Retail Assistant at Cats Protection charity shop in Derby. I am studying maths and science to be a veterinary nurse. I found the videos really useful for revision and homework.
Thanks for the comment, I appreciate it. I'm glad that my videos are helping with your studies. And thanks for being a freesciencelessons supporter.
when u have 2 go back 2 basics 1 week b4 exam starts
It's 2 days now and I don't know anything

Fab videos..thank you. Could you please provide a small test at the end of each video so we are able to summarise whether we have learnt the subject. When will the workbooks be available please? Thank you

I love you so much ahh! Thank you so much for these videos, I'm currently failing, well every science. (By that I mean getting average 60%, and I'm not actually understanding everything.) I'm in year 10, and so I still have time for year 11, Which is why I'm learning everything right now WAY before my exams. I'll update you guys on how well I do!

Dear Sir,
Just asking, are these videos meant for the combined foundation, higher, or trilogy AQA GCSE?
It's definitely on the AQA higher Biology specification so if you're looking for that then it's good.
Those last minute revision 😂 good luck u man
Hello Raman I am in jeddah
And I am preparing for ilets and gcse 🤲
I love the intro music
good luck lads
saved my life
Anyone here binging the new playlist
Binging ready for my y10 mocs
Day before the exam grind
sir, what music do you like? thanks for these vids btw, gcses start on monday n im so worried
I like a lot of singer-songwriter music from the 1970s.
Don't worry about your exams. Just keep revising and remember that loads of students (that you will be competing with) do virtually no revision at all.
thanks sir! and i LOVE seventies music - supertramp are my favourite at the moment.
that isn't singer songwriter but hey ho
Freesciencelessons Hi, just one question, Prokaryotics are 0.5um-5um in size, what about eukaryotics? everyone has a different answer. Thanks

His sir,
Do I need to all the measurements in this videos- what in this videos should I write flashcards from?

You need to be able to say the sizes eg 1 micrometer is 1 millionth of a metre etc and also write them in standard form eg 1 x 10 -6 m

For people who doesnt have cells you have to
The subtitles on this video are incorrect. especially while trying to make sense of it. like a word music ER. no idea what this was suppose to say and i would like to have more punctuation in the subtitles aswell or perhaps a transcript.
Hi. The subtitles are done by youtube's voice recognition system and are not always reliable. However, on most of the videos, the words on the pages cover all the points that I'm saying, so any deaf viewers can use them without needing the subtitles.
He isnt putting down the words in the subtitles the subtitles is putting words down by itself , words it thinks it hears
2021 anyone
Anyone else begging for a pass tomorrow
Class of 2022 wya?
