Explanation:
1. The cell is present in some type of cells. It is found in plants and bacteria and some others. It is present or found outside the plasma membrane.
2. The functions of cell wall are that it provides tensile strength and protection to the cell against many type of stress. It also plays very important role in many others protections for the cell. There are two layer, named as primary cell wall and secondary cell wall.
3. Composition of Plant cell walls is that they are primarily made of cellulose. Cellulose fibers are linear long polymers of around 100 molecules of glucose. These fibers cluster into bundles, known as or called microfibrils. In plants the microtubule cytoskeleton are present, and there function is that they directs the orientation of cell wall as in which orientation cellulose is deposited in the cell wall.
