GENERAL HISTOLOGY

Detailed explanation-1: -The cell wall is present only in plants and in some fungi, bacteria and algae. It is present outside the cell membrane and is tough, flexible and sometimes rigid in its texture. It is mainly composed of cellulose, long fibres of carbohydrates including hemicellulose, lignin and pectin.

Detailed explanation-2: -A cell wall is a rigid, semi-permeable protective layer in some cell types. This outer covering is positioned next to the cell membrane (plasma membrane) in most plant cells, fungi, bacteria, algae, and some archaea. Animal cells however, do not have a cell wall.

Detailed explanation-3: -A cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell. The cell wall contains not only cellulose and protein, but other polysaccharides a s well . The cell wall provides structural support and protection.

Detailed explanation-4: -The part of a cell that provides structural support and protection is the Cell wall. A cell wall is a firm and rigid structure that surrounds the cell membrane. Many different types of cells have a cell wall, including plants, fungi, bacteria, and archaea.
