Detailed explanation-1: -Chloroplasts are double-membraned organelles present only in plant cells.

Detailed explanation-2: -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-3: -The plastid is a double-membrane organelle found in the cells of plants and algae. Plastids or chloroplasts are not found in the animal cells. Plastids are the sites of manufacture and storage of important chemical compounds used by the cell.

Detailed explanation-4: -The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.

Detailed explanation-5: -The organelles found only in plant cells include-chloroplast, cell wall, plastids, and a large central vacuole.
