Question

which is an important difference between light - dependent (l - d) and light - independent (l - ind) reactions in photosynthesis? the l - d reactions need co₂ and light energy, and the l - ind reactions needs water and o₂. the l - d reactions require light energy and water, and the l - ind reactions require atp, nadph, and co₂. the l - d reactions can only occur during daylight, and the l - ind reactions can only occur during the night. the l - d reactions need water and co₂, and the l - ind reactions need co₂ and light.

Explanation:

In photosynthesis, light - dependent reactions use light energy and water to produce ATP, NADPH, and release oxygen. Light - independent reactions (Calvin cycle) use ATP, NADPH, and CO₂ to fix carbon and produce carbohydrates. They don't require light directly.

Answer:

The L - D reactions require light energy and water, and the L - IND reactions require ATP, NADPH, and CO₂.
