GENERAL HISTOLOGY

Detailed explanation-1: -Animal cells do not have cell wallsbecause they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if eachcell has its own exoskeleton. This rigidity allows plants to stand upright without the need for bones .

Detailed explanation-2: -No, animal cells do not have a cell wall. They don’t need them. Cell walls are rigid structures found in plant cells. They provide plant cells with much-needed structure, shape, support and protection.

Detailed explanation-3: -In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.

Detailed explanation-4: -The cell wall is present only in plants and some other organisms, not in animals. The main objective of the cell wall in plants is to offer structural support and a permeable surface via which molecules can move inside and outside of the cell.

Detailed explanation-5: -Plastids are only present in plant cells and absent in animal cells. The animal cell possesses a nucleus, plasma membrane, mitochondria, endoplasmic reticulum, etc. Plastids are the large cell organelles present only in plant cells.
