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 do 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. d plants take in water from their leaves through the cuticle.

Explanation:

Plants have root systems that absorb water from the soil. Root hairs increase the surface - area for water uptake. Stomata are mainly for gas exchange, leaves don't take in significant water from air, and the cuticle is a waxy layer to prevent water loss rather than for water uptake.

Answer:

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