(a) Is the cell wall in a plant cell living or non-living?
(b) Is the cell wall in a plant cell, permeable or selectively permeable?
(c) What is its chemical composition?

(a)

1. A cell wall in the plant cell is a non-living component as it is composed of nonliving material called cellulose.
2. It covers the outmost layer of a cell.
3. Its composition varies according to the organism and is permeable in nature.

(b)

1. A cell wall in the plant cell is permeable.
2. Cell wall is fully permeable to water, molecules, and proteins.
3. This allows water and nutrients to be freely exchanged between the plant cells.

( c)

1. The cell wall is mainly composed of carbohydrates like cellulose.
2. Some other compounds like pectin, hemicellulose, protein, and other minerals in smaller amounts also occur in the cell wall.
