Key terms
- Chloroplast
- A microscopic structure inside plant cells where photosynthesis takes place
- Chlorophyll
- The green substance inside chloroplasts that absorbs light energy
- Adaptation
- A special feature or characteristic that helps an organism function and survive in its environment
- Surface area
- The total area of an object's outer surface, which determines how much light a leaf can capture
- Variegated plant
- A plant with leaves containing pale or cream patches that have little to no chlorophyll
- Nucleus
- Controls the cell's activities and stores its genetic material
- Cytoplasm
- The jelly-like substance where most of the cell's chemical reactions happen
- Cell membrane
- Controls what moves in and out of the cell
- Mitochondria
- Where respiration releases energy for the cell
- Cell wall
- Strengthens and protects the cell — found in plant cells, not animal cells
- Vacuole
- Stores cell sap and keeps the cell firm — found in plant cells, not animal cells

What this lesson covers
How well do you know each one? Be honest: red means go back over it.
- Explain what an adaptation is and why leaves are adapted for photosynthesis
- Describe the plant cell structures involved in photosynthesis
- Explain the role of chlorophyll and where chloroplasts are concentrated in a leaf
- Explain why leaves are broad and flat, and how surface area affects light capture
- Explain why leaves are thin and how that helps gases move in and out
- Calculate or estimate the surface area of a leaf and explain why it matters
Test yourself

- Which part is found in plant cells but not in animal cells?
- Why do leaves look green to us?
