What structure in plant cells prevents lysis caused by osmosis? a. cell membrane b. nucleus c. cell wall d. chloroplast?

The correct answer is -

c. cell wall.

Explanation:

Cell wall is a rigid, protective layer that is present outside the cell membrane of plants, algae, fungi and most of the prokaryotes.

In plants, it is made up of cellulose and provides structural strength, and also prevents from osmotic lysis.

This is because it acts as pressure vessel and prevents over expansion of cell when water enters it during osmosis (when the cell is placed in hypotonic solution, which has higher concentration of solvent).

Thus, option c) is the right answer.

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying
