Question

Which among the following is incorrect about cell wall?

(a) Cell wall provides mechanical supports and avoids rupture of cell in a hypotonic solution

(b) Plasmodesmata are protein granules in the cell wall that provides mechanical support

(c) Cell wall prevents the cell from invasion and injury

(d) Cell wall is entirely permeable and rigid

I got this question in quiz.

I would like to ask this question from Cell Basics topic in chapter Cell : The Unit of Life of Biology – Class 11

Answer 1

Right choice is (b) Plasmodesmata are protein granules in the cell wall that provides mechanical support

The best I can explain: Cell wall provides mechanical supports and avoids rupture of cell in a hypotonic solution. Plasmodesmata are tiny hole like structures that connects the cell walls of adjacent cells and facilitates communication between the cells. Cell wall is entirely permeable and rigid.
