GENERAL HISTOLOGY

Detailed explanation-1: -The organelles found only in plant cells include chloroplast, cell wall and a vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis.

Detailed explanation-2: -The most characteristic component found in all plant cell walls is cellulose. It consists of a collection of -1, 4-linked glucan chains that interact with each other via hydrogen bonds to form a crystalline microfibril (Somerville, 2006).

Detailed explanation-3: -The cell wall is present only in plant cells but not in animal cells because they provide rigidity and support to plants. The cell wall provides definite shape, strength, and protection against mechanical stress and physical shocks. It helps to control cell expansion due to the intake of water.

Detailed explanation-4: -The organelles found only in plant cells include-chloroplast, cell wall, plastids, and a large central vacuole.

Detailed explanation-5: -Final answer: Chloroplast is found in plant cells but not in animal cells.
