What is Osmosis?

How do molecules move in and out of cells? (Passage of molecules into and out of cells)

Molecules like nutrients and waste products move in and out of cells through diffusion, osmosis, and active transport.

Diffusion is the net movement of ions or molecules from a region where they are higher in
concentration to a region where they are lower in concentration, that is, down a concentration
gradient. Diffusion has been discussed in great detail in our video titled ‘What is Diffusion?’

Osmosis is a special type of diffusion that allows the movement of ions or molecules from a
region where they are higher in concentration to a region where they are lower in concentration
through a partially permeable membrane.

The partially permeable membrane here is the cell surface membrane. The cellulose cell wall is permeable in nature and allows most substances to pass through itself.

Sometimes living cells can absorb certain substances even though these substances are of higher concentration inside the cell than they are outside of the environment. That is, against the concentration gradient.

This process is called active transport and is possible by using energy. Whenever a molecule is absorbed against the concentration gradient, a molecule of energy in the form of ATP or adenosine triphosphate is utilized.

Active transport is involved in several processes occurring within an organism. This
includes the absorption of dissolved mineral salts by root hair. It is also used in
glucose and amino acid uptake by the cells in the human small intestine.

Keep it up
Your channel is a gateway for many students

People can learn new things through osmosis as well . A form of it anyway. Just being exposed to a subject in the form of any medium can and will be absorbed by your mind. This is why we as humans, who care about the course of our lives should always stand guard at the gates of our minds . Taking care to filter the music, television, and other forms of entertainment we indulge in . Feeding our minds with healthy content is just as important as feeding our bodies with healthy food . Maybe more so . God Bless Much Love.

Animation is tremendous, fabulous and fantastic

Video's are very helpful for basic prep for neet

Osmosis is a spontaneous net movement of solvent molecules (water molecules) through a selective permeable membrane into the region of higher solute concentration in the direction that tends to equalize the solute concentration on both sides. (:

Great vid but the narrator needs to slow down a lil bit

More power to you guys 💪 🙌 keep up the great work 👍
