GENERAL HISTOLOGY

Detailed explanation-1: -The correct answer is option 4, i.e., Cell Wall. Cell Wall is found only in plant cells only. It is the outermost covering in the plant cells.

Detailed explanation-2: -Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection.

Detailed explanation-3: -Plant cell walls are made up mostly of cellulose, and also include hemicellulose and pectin. Plant cells connect directly to one another via tunnels in their cell walls called plasmodesmata.

Detailed explanation-4: -Cell wall is present in both animal and plant cell.

Detailed explanation-5: -The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited.
