One of these is present in both plant and animal cell?

The cell is the basic unit of life, and there are two types of cells: plant cells and animal cells. Plant cells have some structures that animal cells do not have, such as cell walls and chloroplasts. However, there is one structure that is present in both plant and animal cells, and that is the cell membrane. The cell membrane is a thin, semi-permeable membrane that surrounds the cell, separating the cell's internal environment from the external environment. It is made up of a double layer of lipids and proteins, and it controls what goes in and out of the cell. In plant cells, the cell membrane is located inside the cell wall, which provides additional support and protection for the cell. In animal cells, the cell membrane is the outermost layer of the cell and is responsible for maintaining the cell's shape. Therefore, the correct answer is cell membrane, which is present in both plant and animal cells.
