Question

water is one of the required reactants for photosynthesis. it provides electrons that are energized by sunlight and used to make energy carriers like atp. where oo plants get the water they need for photosynthesis? a plants take in water from the air through their stems. b plants take in water from the soil through their roots. c plants take in water from the air through their leaves.

Explanation:

Plants absorb water for photosynthesis via their root systems from the soil. Stems don't take in water from air, leaves take in carbon dioxide (for photosynthesis) and release oxygen/water vapor (transpiration) but don't absorb water from air for photosynthesis, and the sun isn't a source of water for plants. So the correct way plants get water for photosynthesis is through roots from soil, matching option B.

Answer:

B. Plants take in water from the soil through their roots.
