Plant Cells
Plant cells are the basic structures that make up a plant, and they are responsible for the plant's structure and its ability to photosynthesize. Plant cells are different from animal cells, as they have a tough, protective outer wall made of cellulose, as well as a large central vacuole for storage. Inside the vacuole, cells hold starch grains, pigments and other materials. Plant cells are also able to take up inorganic material for use in photosynthesis. Their cell walls provide protection from the external environment, and their organelles, such as chloroplasts, contain the green pigment chlorophyll, which is required for photosynthesis. Plant cells are important in the production of food and other materials needed for human life, and they are also essential for maintaining the environment by removing carbon dioxide and generating oxygen.
