A plant cell is the structural and functional unit of a plant. Plant cells generally form several different colonies in order to become a higher functioning organism.

While plant cells group together to form higher organisms, each individual plant cell contains many different and important functioning parts. The nucleus and nucleolus make up the main functioning parts of the plant cell. The cell wall surrounds the cell and gives it its shape and structure. The cell membrane, located inside the cell wall, allows elements to enter and leave the cell. The chloroplasts are important for turning light into food for energy.
