As the basic living part of a plant, the plant cell is involved in many physiological and structural activities. They range from synthesis of proteins and energy to maintaining structural integrity and tautness.
Various organelles (sub-cell parts) within the plant cell are dedicated to specific tasks. For instance, the cell wall provides support for the internal parts and protects them from external forces. The chloroplast is involved in photosynthesis. The mitochondria specialize in energy synthesis within the cell. The endoplasmic reticulum is used in the synthesis of ions and proteins, packaging them and storing them. The cell nucleus is the control center from which all the various cellular activities are coordinated.
