Detailed explanation-1: -Hence, the correct answer is ‘cell wall’

Detailed explanation-2: -In Figure 3.8 b, the diagram of a plant cell, you see a structure external to the plasma membrane called the cell wall. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. Fungal and protist cells also have cell walls.

Detailed explanation-3: -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.

Detailed explanation-4: -Bacteria cells are very different from animal, plant or fungal cells. They don’t have organelles such as nuclei, mitochondria or chloroplasts. Although they do have ribosomes and a cell wall, these are both different in structure to the ribosomes and cell walls in the cells above.

Detailed explanation-5: -Some organisms, such as plants, fungi, bacteria, and some protists, have cell walls that surround the plasma membrane and prevent cell lysis in a hypotonic solution. The plasma membrane can only expand to the limit of the cell wall, so the cell will not lyse.
