Question

A plant’s cell wall is made of cellulose fibers. What is the purpose of a plant’s cell wall?

Answer 1

Hint: Plant cells have a number of unique structures that aren't found in typical eukaryotes. One among the structures is the cell wall. The cell wall allows plants to have sturdy structures and it gives definite shape to it. A plant's cell wall is a specific kind of extrinsic matrix that surrounds each cell.

Complete answer:
Plant cells' plasma membrane is enclosed by a cell wall. The most prevalent macromolecule on Earth, cellulose, is employed to build plant cell walls. Hundreds of glucose molecules make up cellulose fibers, which are long, linear polymers. These fibers form microfibrils, which are bundles of around 40 fibers. Microfibrils are contained in a polysaccharide matrix that is hydrophilic.
The purpose of a cell wall in a plant is to perform the following functions:
1. The cell wall gives the plant its distinct shape, vigor, and resilience.
2. It also guards the plant from mechanical stress and physical shocks.
3. It aids in the control of cell growth caused by water intake.
4. Additionally, it aids in the inhibition of water loss from the cell.
5. It is in charge of moving molecules within and beyond the cell.
6. It serves as a shield between the inside cellular components and the outer surroundings.

Note:
The plant cell wall is made up of three layers of carbohydrates, such as pectin, cellulose, and hemicellulose, as well as minimal amounts of minerals, that create a connection with structural proteins to form the cell wall. The cell wall's primary function is to furnish structural support and a semi-permeable surface through which molecules can move in and out of the cell.
