Cell Organelles | Worksheet - Free Printable

- Nucleus: The nucleus is often called the brain, or control center, of the cell. It contains genetic material and is responsible for cell growth and reproduction.
- Chloroplast: Chloroplasts are where photosynthesis occurs in plant cells. Photosynthesis produces sugars that plants use for energy and growth. Chloroplasts contain a pigment called chlorophyll, which gives them a green color.
- Mitochondria: The mitochondria, also called the powerhouse of the cell, are where cellular respiration takes place. This is how the cell turns sugars into the cell’s energy supply.
- Cell Membrane: The cell membrane is the cell’s security guard. It forms the boundary that controls what enters and leaves the cell. It is semi-permeable, meaning only certain substances can pass through it.
- Cell Wall: The cell wall is the outer layer of a plant cell. It gives the cell strength and structure and serves as a protective barrier.
