Video summary: Surface area to volume ratio affects how large cells can be, and explains why transport systems are needed to provide materials to the many cells that make up multicellular organisms.
I can not tell you how many videos and textbook reading I have done to try to understand this concept and this video provided just enogh explanation and cisual for me to finally understand. THANKYOU!!!!
thank you smmm I was so confused by this because every time surface area was mentioned I was like "doesn't the bigger thing (e.g. the human) have a larger surface area?" but you explained it so well, its surface area is larger relatively to its volume. Makes sense. ty
Thank you so much for this! My school sent out worksheets that had the wrong method of working on them, so I was a bit confused. This explains it perfectly. :)
Thankyou so much I was struggling with this concept from pretty long time (subject- botany) I searched in google, repeated my lecture multiple times but didn't understood You explained it in no time n that too very clearly Thanks a lot ❤
It's really nice since I cannot find anything better. But just one little comment, I find it quite annoying when the hand keeps on typing on the right when I wanted to focus on the information.
Wait is it cos I'm new to his videos or something? Why is no one talking about how impressive the button pressing idea was at the side of the page? Everytime he was gonna tap the button, my brain entered an automatic state of better perception and anticipation (about what's the new term or diagram that's gonna be shown) This IDEA IS COOOOOOOOOOOOOOL
i came from hhere bcz i didn't get what the following means: The bigger a cell or structure is, the smaller its surface area to volume ratio is, slowing down the rate at which substances can move across its surface Many cells which are adapted for diffusion have increased surface area in some way - eg root hair cells in plants (which absorb water and mineral ions) and cells lining the ileum in animals (which absorb the products of digestion) now i do
2:20 my brain hurts 😵💫 don't all cubes have the same surface area to volume ratio? how on earth can they not. I mean you can take the 2x2x2 cube and just rename the length to 1x1x1 and get a ratio of 6:1 fascinating how a cube with 6*6*6 have a ratio of 1:1
High school Science is mostly about providing a foundation to lead you to your chosen profession. Some professionals may rely on this knowledge to provide understanding of more complex ideas. Others might not. Will this help you pay your taxes, cook a meal, or arrange a mortgage? No, certainly not. But I believe all knowledge has the potential to take you somewhere, and learning something you later find you don't need won't have done you any harm. There are few things in this world that open more doorways than education and, on RU-vid, it's free. I encourage you to take every opportunity you get and wish you the best of luck through high school and on to your adult life. PS If there's anything you don't understanding in the video, I'd be happy to explain further.
