10. How do plants make food during the process of photosynthesis? • Plants make food by trapping sunlight and absorbing CO2 & water.

11. What part of the plant traps the sun’s energy? • The part of the plant that traps the sun’s energy is the chlorophyll in the leaves.

12. What are the jobs of the roots? • The roots jobs are to take in water, support the plant, absorb nitrogen compounds, and store glucose (to be used at night for energy).

13. Describe how Elodea and Duckweed are different? • Elodea has leaves and a stem. • Duckweed grows in fronds and floats on the surface.

14. What do Algae and Duckweed have in common? • Algae and Duckweed both have no leaves or stems.

16. How does Duckweed grow and reproduce? • Duckweed grows and reproduces by having buds attached to the fronds.

17. What problems does Duckweed cause when it thrives? • Duckweed can cause problems by blocking out the sunlight on the water’s surface.

18. What problems does Elodea cause when it thrives? • Elodea can cause problems by growing rapidly. This will clog waterways and drainpipes.
