Question

Which option accurately describes the first two stages of photosynthesis?




Stage 1: A chlorophyll electron enters the stroma. Stage 2: ATP becomes ADP and NADPH becomes NADP+.



Stage 1: The thylakoid captures light energy. Stage 2: Chlorophyll converts it to chemical energy.



Stage 1: The thylakoid membrane of a granum captures light energy. Stage 2: Water and oxygen provide an excited electron as an energy source.



Stage 1: Light energy causes an electron to enter an excited state. Stage 2: ADP becomes ATP and NADP+ becomes NADPH.

Answer 1

The answer is Stage 1: The thylakoid captures light energy. Stage 2: Chlorophyll converts it to chemical energy.

Photosynthesis is a process in which plant produce sugar and oxygen from water and carbon dioxide using the energy of sunlight. Cells of the green leaves contain chloroplasts. Thylakoids are the part of chloroplasts where the light-dependent reactions of the photosynthesis occur. They capture light energy, so chlorophyll inside the chloroplast can convert it to chemical energy.

Answer 2

I just took the quiz with my son. The answere was Stage 1: Chlorophyll captures light energy. Stage 2: Light energy is converted to chemical energy.
