- 4. a organelle in plant cells where photosynthesis.
- 6. is good for plants to have the light of the sun and so it can make food.

- 9. starts when chlorophyll absorbs energy from sunlight. Photosynthesis happens in two steps.

Down
- 1. are water (H2O) and carbon dioxide (CO2).
- 3. dioxide enters plants from the air through stoma, small openings on their leaves.
- 5. contain chlorophyll, a green pigment that soaks up the radiant energy needed for photosynthesis directly from sunlight.
- 8. in the progress of photosynthesis the plant lets out oxygen for us to berth.
- 10. light-dependent reaction occurs, followed by the light-independent reaction.
