The plant cell is a basic unit of life found in all plants. It is characterized by a rigid cell wall made of cellulose, which provides structure and support. Inside, plant cells contain organelles such as chloroplasts, which are responsible for photosynthesis, and a large central vacuole that stores water and nutrients. Plant cells also have a nucleus that houses genetic material, allowing for growth and reproduction. Unlike animal cells, plant cells do not have centrioles. The unique features of plant cells enable them to perform essential functions that support the life of the entire plant, contributing to processes like photosynthesis and growth.
