1. DIFFUSION
The movement of molecules from a region of higher
concentration towards a region of lower
concentration is known as dif fusion.
2. OSMOSIS
It is a process in which water molecules travel from a region of its
higher concentration to a region of its lower concentration through
a selectively permeable membrane.
Practice preparing isotonic solution, hypotonic solution and hypertonic solution. Find out the effect of these solutions on plant and animal cell. Discuss the terms turgid, flaccid, lysis, plasmolysis.
