Question

in photosynthesis, why is water important? a b) c) d) it provides the carbon needed for sugar it prevents plants from using sunlight it dissolves oxygen into sugar it supplies electrons and hydrogen for making glucose

Explanation:

In photosynthesis, water is split during the light - dependent reactions. This supplies electrons to replace those lost by chlorophyll and also releases hydrogen ions. These hydrogen ions are used in the synthesis of glucose during the Calvin cycle. Carbon for sugar comes from carbon dioxide, water does not prevent plants from using sunlight, and oxygen is a by - product, not dissolved into sugar.

Answer:

D. It supplies electrons and hydrogen for making glucose
