Question

All living things are made of one or more cells. Here are two types of cells: an animal cell and a plant cell. Sometimes when plants are under water stress, they wilt. Animals do not wilt! What analogy based on the plant cell structure explains wilting?

Answer 1

Osmosis - the control of letting water pass through our cells

Answer 2

Answer:

Presence of cell wall around the plant cells.

Explanation:

An adequately hydrated plant cell is firm due to presence of turgor pressure. Loss of water results in loss of turgor and the plant cells become limp and exhibit wilting. Irrespective of loss of turgor, presence of rigid cellulosic cell wall around the plant cells maintain their structural integrity.

On the other hand, animal cells do not have cell walls around them which in turn do now allow them to maintain the structure after loss of water.
