NEET BIOLOGY

Detailed explanation-1: -Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant’s life style.

Detailed explanation-2: -Cell WallThe cell wall is a rigid layer that surrounds the cells of plants and some other organisms. The cells of animals, in contrast, do not have cell walls. A plant’s cell wall helps protect and support the cell. The cell wall is made mostly of a strong material called cellulose.

Detailed explanation-3: -The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.

Detailed explanation-4: -The correct answer is the Cell wall. A cell wall can be defined as a rigid layer that encircles the contents of the cell. This is a semi-permeable layer that acts as a protective layer in certain types of cells.

Detailed explanation-5: -Cells of bacteria, fungi, algae, and higher plants are surrounded by rigid cell walls, which are an integral part of the cell. Although not encased in cell walls, animal cells in tissues are closely associated with an extracellular matrix composed of proteins and polysaccharides.
