What is the purpose of a plant’s waxy covering?

• It makes the plant more difficult to digest

• It allows the plant to retain water.

• It reduces the risk of the plant burning during a wildfire

• It prevents rainwater from seeping into the plant.

A scientist is investigating photosynthesis using two leaves on a plant.

One leaf is covered with black paper while the other leaf is left

uncovered. The plant is placed in direct sunlight for several hours. The

scientist then tests for the presence of starch in each leaf. What are the

most likely results from this experiment?

• Both leaves will have experienced photosynthesis.

  .

• Both leaves will have been unable to experience photosynthesis

• The covered leaf will have experienced photosynthesis, while the

  uncovered leaf will not have

• The uncovered leaf will have experienced photosynthesis, while the

  covered leaf will not have.

Stomata involved in transpiration are most often found where on a plant?

• the flower

• the roots

• the underside of the leaf

• the top of the leaf

Which statement best explains the importance of respiration in a green

plant?

• It builds plant structure during transpiration.

• It releases energy for the plant to perform its functions

• It pumps water to the leaves of the plant

• It makes food and energy for the plant.

How do stomata help a plant maintain balance with their environment?

• by releasing energy

• by releasing excess food

• by releasing water vapor

• by releasing sunlight

What is the importance of transpiration in a green plant?

• to warm water to keep the plant hydrated

• to pump water and minerals throughout the stem and leaves of the

  plant

• to make food and energy for the plant

What is the relationship between photosynthesis and respiration?

• Respiration produces glucose, and glucose is required for

  photosynthesis

• Respiration requires sunlight, while photosynthesis does not.

• Photosynthesis produces oxygen, and oxygen is required for

  respiration.

• Photosynthesis produces water, while respiration does not
