Cell wall of bacteria is not made up of cellulose.

Explanation:
The cell wall is a rigid layer that surrounds the cell membrane of plants, bacteria, fungi, and some protists. It provides structural support and protection to the cell. In plants, the cell wall is mainly composed of cellulose, a complex carbohydrate made up of glucose units bonded together.

Cell wall of Mango tree:
The cell wall of a mango tree is made up of cellulose. Cellulose is a major component of plant cell walls, providing strength and rigidity to the cells.

Cell wall of Hydrilla:
The cell wall of Hydrilla, which is an aquatic plant, is also made up of cellulose. Cellulose is essential for maintaining the shape and structure of plant cells.

Cell wall of Bacteria:
Unlike plants, the cell wall of bacteria is not made up of cellulose. Bacterial cell walls have a different composition, depending on the type of bacteria. Most bacteria have a cell wall made up of peptidoglycan, a polymer composed of sugars and amino acids. This peptidoglycan layer provides strength and protection to the bacterial cell.

Cell wall of Cactus:
The cell wall of a cactus is made up of cellulose, just like other plant cell walls. Cellulose is important for maintaining the shape and structure of the cactus cells, especially in drought conditions.

Conclusion:
In summary, the cell wall of bacteria is not made up of cellulose. Instead, it is composed of peptidoglycan, a polymer that provides strength and protection to bacterial cells. The cell walls of plants, including mango trees, hydrilla, and cacti, are made up of cellulose, which provides structural support to these organisms.

Hydrilla plant shows the presence of cellulosic cell wall surrounding its cell membrane.
