True False The cell wall is composed of proleoglycans and collagen, providing support and maintaining the shape of plant cells. It is flexible, allowing for easy expansion of plant cells. The cell wall also isolates individual plant cells and helps resist infection by plant pathogens. There are connections between adjacent cells in the cell wall, which aid in communication and transport.
Md.Daniyal A.
Check your understanding. What did you include in your answer? A cell membrane, seen in plant and animal cells, is selectively permeable and made of a phospholipid bilayer. The cell membrane and cell wall control what enters and leaves the cell. The cell wall is seen in a plant cell, gives shape to the cell, and stores carbohydrates. The cell wall is selectively permeable and made of cellulose, which causes plants to have a rigid structure.

Cell walls: a) only occur in plant cells. b) are not completely solid, having many small pores. c) confer less structural support than the plasma membrane. d) dissolve when a plant dies. e) are made primarily from phospholipids.
