Plant cell functions are complex and serve different purposes. The different parts of the plant cells are responsible for functions that work together to enable the plant to obtain nutrients, change sunlight into food, pass forward genetic material, conduct cell division, store food, and maintain structural support. Each part of a plant cell plays a role. The cell wall provides the plant with rigidity. The cell membrane is a gel like substance that enables substances to enter and exit the cell. Chloroplasts in the cell contain chlorophyll. The plant cell engages in the process of photosynthesis with the absorption of sunlight into the chloroplasts. In the chloroplasts light is converted to energy or food. The energy is stored in the vacuoles located in the gel like substance called cytoplasm. The mitochondria has the job of converting glucose into energy. The nucleus serves as the coordinator of the activities and holds most of the plants genetic material that will be shared in mitosis. The plant cell must then function as a replicator through cell division which leads to the creation of one cell separating into two cells.
