Detailed explanation-1: -The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.

Detailed explanation-2: -Cell membrane: The cell membrane contains the contents of the cell and provides a barrier to control what enters and leaves the cell.

Detailed explanation-3: -The nucleus is present in both types of cells and controls the general activities of the cell, including gene expression and cell division. Of these answer choices, only chloroplasts are present in plants cells, but not animal cells.

Detailed explanation-4: -The membrane is a delicate, two-layered structure of lipids and proteins, and it controls what can enter and exit the cell.

Detailed explanation-5: -The function of the cell membrane is to regulate the flow of water and other material in and out of the cell. It also acts as a protective barrier. Animal cells simply have a cell membrane, but no cell wall.
