HORTICULTURE

Detailed explanation-1: -The cell wall is the outer covering of a cell, present adjacent to the cell membrane, which is also called the plasma membrane. As mentioned earlier, the cell wall is present in all plant cells, fungi, bacteria, algae, and some archaea.

Detailed explanation-2: -A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.

Detailed explanation-3: -What Is the Cell Wall? A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein. These components are organized into three major layers: the primary cell wall, the middle lamella, and the secondary cell wall (not pictured).

Detailed explanation-4: -Algae, fungi, and plant cells have a cell wall; animal cells and protozoans lack cell walls.

Detailed explanation-5: -The cell wall is the outermost covering of a plant cell. It is a tough and flexible (sometimes rigid) layer that provides structural support and protection to the cell. Animal cells do not have a cell wall.
