The parts of the plant cell are as follows: Plants cell constitute of membrane bound nucleus and many cellular structures. These organelles carry out funct ions that are necessary for the proper functioning and survival of the cell. The cell orga nelles of the plant are enclosed by a cell wall and cell membrane.
Within each cell are a number of elements, such as mitochondria that converts sugars into energy the plant can use, and chloroplasts that contain the chlorophyll the plant uses in photosynthesis. But by far the largest portion of each cell is the vacuole, a space filled with water that ensures the cell maintains its shape.
