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: -Typical components of the cell wall include cellulose, non-cellulosic, and pectic polysaccharides, proteins, phenolic compounds, and water.

Detailed explanation-3: -Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

Detailed explanation-4: -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-5: -The cell wall separates the interior contents of the cell from the exterior environment. It also provides shape, support, and protection to the cell and its organelles. However, this cellular component is present exclusively in eukaryotic plants, fungi, and a few prokaryotic organisms.
