5.5 Plant cells
Plants, like all other organisms, consist of cells. Cells are small, but they can be easily studied with a fluorescent microscope, for example.
Plant cells contain various organelles and structures. These include:
- The cell wall, which is the outermost structure of the cell. It protects and supports the structure of the cell.
- The cell membrane, which is a thin layer of plasma that regulates the movement of substances in and out of the cell.
- Cytoplasm, which is a mixture of liquids that is located inside the cell.
- The nucleus, which contains the cell's genome in its chromosomes.
- Chloroplasts, where the process of photosynthesis takes place.
- The vacuole, which is used to store water and other essential substances.
