Which of the following organelles is common to both plant and animal cells

The organelle that is common to both plant and animal cells is the cell membrane. The cell membrane is a thin, semi-permeable layer that surrounds the cell and separates its internal environment from the external environment. It is made up of lipids and proteins, and its main function is to control the movement of substances in and out of the cell. In both plant and animal cells, the cell membrane is essential for maintaining cell integrity and regulating the exchange of nutrients, gases, and waste products with the surrounding environment. While plant cells also have a cellulose cell wall and a large central vacuole, animal cells do not have these structures. Chlorophyll, on the other hand, is a pigment found in plant cells that is responsible for absorbing light energy during photosynthesis. It is not present in animal cells. Therefore, the correct answer is the cell membrane.
