If a plant cell wall becomes flexible, the cell will lose its rigidity and shape. It may shrink under stress and fail to support the plant, affecting its structure and stability.
Plants need a rigid cell wall because they are fixed and must withstand environmental forces. Animals move and need flexible cells, so they do not have a cell wall.
If soaked mung bean seeds are placed in a concentrated solution, they will lose water due to osmosis. As a result, the seeds will shrink and become smaller in size.
Cells are studied using microscopes because they are too small to be seen by the naked eye. Light microscopes and electron microscopes help in observing cell structures and understanding their functions clearly.
