GENERAL HISTOLOGY

Detailed explanation-1: -Plasma membrane is the outermost protective layer in cells of all plants and animals.

Detailed explanation-2: -The cell membrane or plasma membrane is the outermost layer of an animal cell, while in plant cells, it lies inner to the cell wall.

Detailed explanation-3: -Plant cells have a cell wall, as well as a cell membrane. 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: -Most cellular activities take place within the cytoplasm, such as many metabolic pathways including glycolysis, and processes such as cell division. The concentrated inner area is called the endoplasm and the outer layer is called the cell cortex or the ectoplasm.
