* Chloroplasts: These are the sites of photosynthesis, the process by which plants convert sunlight into energy. They contain chlorophyll, the green pigment that absorbs light energy.

* Cell Wall: A rigid outer layer that provides structural support and protection to the plant cell. It is composed mainly of cellulose.

* Vacuoles: These are large, fluid-filled sacs that store water, nutrients, and waste products. They also help maintain turgor pressure, which keeps the plant upright.

* Plasmodesmata: These are small channels that connect the cytoplasm of adjacent plant cells, allowing for communication and transport of molecules.
