Question

1. plants have structures that help perform many physiological processes that are required for the plants survival. which of the following statements correctly pairs a plants structure to its function?

a a plants leaves absorb water from the environment that can be used during the process of anaerobic respiration.
b a plants guard cells protect the plant from harsh environmental conditions, pests, and diseases that could harm the plant.
c a plants chloroplasts are responsible for producing the green pigment required to attract the pollinators necessary for fertilization.
d a plants stomata are responsible for allowing gases to exchange between the leaf and the environment during the process of photosynthesis.

Explanation:

• Option A: Roots, not leaves, absorb water. Anaerobic respiration is not the main use of absorbed water.
• Option B: Epidermal cells (not guard cells) protect the plant from harsh conditions, pests, and diseases. Guard cells control stomatal opening and closing.
• Option C: Chloroplasts are for photosynthesis (not for producing pigment to attract pollinators). Petals often have pigments for pollinator attraction.
• Option D: Stomata allow gas exchange (e.g., intake of \(CO_2\) and release of \(O_2\)) during photosynthesis.

Answer:

D. A plant’s stomata are responsible for allowing gases to exchange between the leaf and the environment during the process of photosynthesis.
