Which option accurately describes the first two stages of photosynthesis?
a) stage 1: chlorophyll captures light energy. stage 2: light energy is converted to chemical energy.
b) stage 1: light energy is converted to chemical energy. stage 2: chloroplasts capture the chemical energy.
c) stage 1: the granum captures light energy. stage 2: the thylakoid converts it to chemical energy.
d) stage 1: the thylakoid captures light energy. stage 2: chlorophyll converts it to chemical energy.

Answer;

A) Stage 1: Chlorophyll captures light energy. Stage 2: Light energy is converted to chemical energy.

Explanation;

-Photosynthesis is the process by which green plants use energy from the sun, water and carbon dioxide to make organic compounds such as simple sugars together with release of oxygen.

-The process occurs in tow stages; light-dependent stage and light independent stage. During light dependent stage, chlorophyll absorbs sunlight and uses it to split water molecules into hydrogen ions and oxygen atoms. In the light independent stage carbon (iv) dioxide is fixed and the result is organic compound; the light energy is converted to chemical energy.
