What is Diffusion? How Does it Work? What Factors Affect it? #7
This video covers
- What diffusion is
- How it works
- How it applies to cell membranes
- The 3 factors that affect the rate of diffusion (concentration gradient, temperature, surface area)
Exam board specific info:
KS3
All relevant to KS3 course
GCSE
AQA - All on your course
IGCSE Edexcel - All on your course
Edexcel - All on your course
OCR 21st Century - All on your course

A-level
If you're doing A-level biology you also need that longer diffusion distances will decrease the rate of diffusion because the particles have to travel further.

Yeah same this is basically getting me thru my gcses
This is the most fantastic gcse channel I've seen. I get so appealed to the animations and the way the video is explained. On the other side, it is also short and precise. Thank you so much for your amazing effort.
im really happy to be able to stumble upon this channel.I have no idea how to study for biology as the notes given are very content heavy. I love how this channel summarises key points and makes it easy to understand. Thank you so much

nahh man, I passed and got a 93% on bio bc of u for real you know how t explain it really well in LITERALLY 5 mins nt 45 mins. Im a senior now taking AP bio nd this has helped a lot. Thank you Cognito.
Had to watch this in class 💀 thanks for making my day more interesting
These videos are great! I share these with my students at the beginning of the lesson to give them an interesting kick start to the topic!! 👍👌

Hi! my teacher does the same but in a classroom it doesn’t help me all that much because i’m prone to zoning out because he doesn’t do anything that keeps our minds on this video, so could i suggest for your students maybe pausing the video every so often in the video and asking questions to ensure they’re actively watching it?
I have a test today and these videos will get me happy results! Thank you 😊
I am really happy I saw this channel, the videos you post are really helpful and I am really grateful for learning biology, chemistry, physics and maths from the channel, it helped me alot. thank you so much!

Hi I was just wondering how is a concentration gradient maintained? Thanks :)
This channel is awesome helped me learn about the subjects I struggle in at school thank you for this channel
Love these videos, especially for someone like me who struggles with reading.
I have a test tomorrow, and one vid in I feel more comfortable with it! So clear, that really helps and it's really simple 😊 thank you so much

Hello, I am a teacher, but I am learning from you ... the content you provide is very, very wonderful ... but I ask you to add the translator to the videos because I am only fluent in Arabic ... Please add Arabic to the scientific videos

What's the difference between a partially permeable membrane and a semi permable membrane because semi permeable is what i get taught at school
ty im revising for a test that i forgot i had xD
Yes
am I bugging or is perfume another form of liquid and when u spray perfume it's just small liquid particles in the air
question where does it come from
3:09 is this called osmosis? Thanks for the great video, so much easier to understand! Keep up the good work, we appreciate it ;)

Hi, I had a question, since you said diffusion happens when particles move from a high concentration to where there is a low concentration, is it possible that almost all the particles try to move to a low concentration area at once, making that area concentrated? And then, does this process repeat, with the particles going back to now low-concentration areas?
@duaahmed8645
Жыл бұрын
No the particles move from a higher concentration to a lower concentration until the concentration is balanced on both sides

Can you also teach English grammar on this channel.
i havent been attending the class' lectures and your videos are lifesaving when it comes to understaning the concepts! thank you so much for all your effort!
If I get an A in biology its cuz of this ✨🙏
Lovely😂❤😊
Why professor say :cell membrane are semipermeable, phospholipid bilateral, easily permeable to lipid-soluble molecules such as O,CO2,steroid hormones. Impermeable to amino acids,sugars, protein. Which contradicts what u said?
Thank you so much....great channel, helps A LOT. Very clear and attractive explanations. Makes it much easier to grasp the harder concepts. Your videos are used frequently during our online classes. Good luck, looking forward for more videos...🤩🙏
Only people who finished the whole bio playlist can like this comment Also amazing playlist Cognito, a moment of silence for every GCSE student revising without you 😔
Oh? Is the biology playlist not yet complete?
would you consider doing videos for A-level biology and chemistry?
