Which organelle in the table is correctly matched with its function?
chloroplast
cell wall
cell membrane
vacuole
chloroplast - site of photosynthesis in plant cells
The correct match for each organelle and its function is as follows:
1. Chloroplast: The function of a chloroplast is to carry out the process of photosynthesis in plant cells. Photosynthesis is the process by which green plants and some other organisms convert sunlight into chemical energy to fuel their growth.
2. Cell wall: The function of a cell wall is to provide structure, support, and protection to the cell. It is a rigid outer layer found in plant cells, fungi, bacteria, and some protists. The cell wall helps maintain the shape of the cell and provides protection against mechanical stress.
3. Cell membrane: The function of a cell membrane, also known as the plasma membrane, is to regulate the passage of substances in and out of the cell. It acts as a selectively permeable barrier, allowing certain molecules to enter or leave the cell while preventing the passage of others. The cell membrane also plays a role in cell signaling and cell adhesion.
4. Vacuole: The function of a vacuole is to store water, nutrients, waste products, and other substances within the cell. In plant cells, vacuoles also help maintain turgor pressure, which is essential for plant cell structure and support.
So, the correct match of each organelle with its function is:
- Chloroplast: Carries out photosynthesis.
- Cell wall: Provides structure, support, and protection to the cell.
- Cell membrane: Regulates the passage of substances in and out of the cell.
- Vacuole: Stores water, nutrients, and waste products within the cell.
