Question

2. In what way is active transport opposite to
diffusion?
3. A cell kept in a certain solution bursts after
some time. Comment upon the kind of
solution.
4. Which process, diffusion, osmosis or active
transport, needs involvement of energy ?
5. Can we call diffusion passive transport ? If
so, how?​

Answer 1

Answer:

Active transport works in the opposite direction; it moves molecules from a low concentration to a high concentration, against the concentration gradient. This is the opposite of diffusion and osmosis. And because it is not the natural direction, energy from is required to make this work.

Hypotonic solutions have more water than a cell. Tapwater and pure water are hypotonic. A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
