Cell Organelles

A cell is a tiny factory, and the organelles are its specialized stations. Each one has a job: storing instructions, making proteins, producing energy, or recycling waste. The diagram below shows the parts of an animal cell and a plant cell. Click any organelle to see its role, key facts, and what NEET typically tests about it.

Cells in life are messier and three-dimensional than the diagram above. This is a textbook simplification to help you learn the parts; real micrographs show overlapping, dynamic structures.
How to read this diagram. Click any organelle in the cell to see what it does and where it appears. Switch tabs to compare animal and plant cells, or open the Differences view to see only the organelles unique to each. Cells in real life are messier and three-dimensional; this is a tidy textbook view to help you learn the parts.
