Review Plants and photosynthesis before starting →Ideas to recall
- Photosynthesis uses light energy to build sugars from carbon dioxide and water.
- Chlorophyll absorbs light in chloroplasts.
- Stomata regulate gas exchange and water loss.
- Plants also perform cellular respiration.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.

Assessment Coverage & Question Outline
This assessment contains 5 multiple-choice challenge questions designed to evaluate core conceptual understanding and practical application of Plants and photosynthesis. Review the questions below to test your recall or use the interactive assessment above for real-time validation and detailed step-by-step explanations.
What does photosynthesis use to build sugars?
- A.Light energy, carbon dioxide, and water
- B.Oxygen and soil alone
- C.Only heat from the air
What is the role of chlorophyll?
- A.It pumps blood through the plant
- B.It absorbs light used in photosynthesis
- C.It breaks rocks into soil
What do stomata regulate?
- A.The number of roots underground
- B.The age of every plant cell
- C.Gas exchange and water loss from leaves
Do plants carry out cellular respiration?
- A.Yes, they use respiration to release usable energy from sugars
- B.No, only animals respire
- C.Only when no cells are alive
Why is water transport important to a plant?
- A.Water replaces the need for carbon dioxide
- B.Water is needed for photosynthesis, cell function, and moving dissolved minerals
- C.Water is converted directly into soil
