Cells are the basic units of life, which make up all living things. This idea forms the basis of the Cell Theory. Plant cells are larger because they contain all of these structures but have some unique structures like a cell wall, vacuole and chloroplasts.
All these specialised structures are called organelles. An organelle is a tiny structure inside an animal or plant cell that has a specific function or role.
