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.

Answer;

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

Explanation;

-Photosynthesis is the process by which green plants use light energy from the sun, water and carbon dioxide to make organic molecules, such as simple sugars.

-The process takes place in two phases; light dependent stage and light independent stage.

-During light dependent stage light energy is used to break down water molecules into hydrogen ions and oxygen atoms.

-Light independent reactions uses CO2 and the ATP and NADPH from light dependent reactions to produce sugar/ glucose. ATP is used to provide the energy for sugar synthesis and NADPH is used for electrons in the reduction of Carbon Dioxide into sugar.
