Question

level 4 q2 four identical plants are grown under different colored light bulbs. under which color will the release of oxygen gas be the slowest? a. blue b. orange c. green d. red a. blue b. orange c. green d. red

Explanation:

Plants contain chlorophyll, which reflects green light and absorbs other colors (blue, orange, red) for photosynthesis. Photosynthesis produces oxygen, so when light absorption is low (like for green light, as chlorophyll reflects it), the rate of photosynthesis and thus oxygen release is slowest.

Answer:

C. Green
