Dear vaibhav.ramasamy@gmail.com
Thanks for asking us questions in Ask the Expert section of TopperLearning.com.
In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
The solution to one of your expert queries is provided below-
Exosmosis is the inward diffusion of water through a semi-permeable membrane when the surrounding solution is less concentrated. This tends to swell up the cell.
Endosmosis is the outward diffusion of water through a semi-permeable membrane when the surrounding solution is more concentrated. This causes the cell to shrink.
