Question

4 multiple choice 20 points during photosynthesis, a plant requires carbon dioxide. how does the plant absorb the gas from the atmosphere? the plant absorbs carbon dioxide through the stomata on the leaves. the plant absorbs carbon dioxide through the roots in the soil. the plant absorbs carbon dioxide through the flowers. the plant absorbs carbon dioxide from the chloroplasts in the cells.

Explanation:

To determine how a plant absorbs carbon dioxide during photosynthesis, we analyze each option:

• Roots absorb water and minerals, not carbon dioxide from the atmosphere, so the option about roots is incorrect.
• Flowers are for reproduction, not gas absorption, so the flowers option is wrong.
• Chloroplasts are the site of photosynthesis (where reactions occur), not where carbon dioxide is absorbed from the atmosphere.
• Stomata are small openings on leaves that allow gas exchange, including the intake of carbon dioxide from the atmosphere.

Answer:

A. The plant absorbs Carbon Dioxide through the stomata on the leaves.
