Biology Lecture - 19 - Osmosis

[MsSusu-uzqx]

I have a cell biology exam in 5 days, and im stressed as hell these are my last 7 credits....And i wont lie, iève learned more about biology than i did when i was at the university. The short tutorials, is perfec and i couldnèt ask for anything better than this- and youère smart and confident and you know it inside out.... well done, keep up the great work

I love your tutorials they really help a lot thanks! :) at 6:25 which side is now the inside of the cell? Left (with only the water) is the inside, right?

[dgwunderwaffle]

Haha awesome tutorial dude - we do tend to learn it as water moves from an area of high concentration to low concentration across a selectively permeable membrane in the UK! But thanks anyway, will take this new info onboard!

This is a great video, thanks! I'd really like to see one on hypertonic vs. hypotonic. I am really struggling with how to know which is which.

No, Diffusion is the NET movement of PARTICLES moving from a region with higher concentration to a region of lower concentration down a concentration gradient. (no need the membrane.)

[mrpeekabooelmo]

Diffusion is the movement of molecule from a place of high concentration to a place of low concentration through a semi-permeable membrane.

Osmosis is the movement of molecules from a place of high water concentration to a place of low water concentration through a semi-permeable membrane.

is this right?

what program do you use to draw? sorry if that question was already asked before D:
nice tutorials by the way! (I normally watch ones about math but I got curious)

[zaemhakim]

where is the active transport tutorial??

[Humbleness]

Have you taught languages yet? You should do that

See the image about osmosis it explains it better:
