This extension applies that lens specifically to Cell Structure and Organelles.
The cell is the basic structural and functional unit of life. Cells are studied under a microscope, and different organelles each do a specific job.
- Cell (plasma) membrane - controls what enters and leaves the cell (selectively permeable).
- Nucleus - contains DNA and controls all cell activities.
- Mitochondria - carry out cellular respiration to release energy.
- Ribosomes - the site of protein synthesis.
- Endoplasmic reticulum and Golgi apparatus - transport and package substances.
- Vacuole - stores cell sap; large and permanent in plant cells.
Plant cells have three extra structures: a cell wall (of cellulose, for support), chloroplasts (for photosynthesis), and a large central vacuole.
