photosynthesis take place in two stages. name the two stages and state whether in the chloroplast each takes place

Question

stage 1
stage2

Answer 1

Photosynthesis occurs in two main stages:

Stage 1: Light-dependent Reactions

• Location in Chloroplast: Thylakoid membranes
• Description: These reactions require sunlight and take place in the thylakoid membranes of the chloroplasts. Light energy is captured and converted into chemical energy in the form of ATP and NADPH. Water is split to release oxygen as a byproduct.

Stage 2: Light-independent Reactions (Calvin Cycle)

• Location in Chloroplast: Stroma
• Description: Also known as the Calvin cycle, these reactions do not require light directly and take place in the stroma of the chloroplasts. The ATP and NADPH generated in the light-dependent reactions are used to convert carbon dioxide into glucose.

Together, these stages allow plants to convert light energy into chemical energy stored in glucose, which can then be used for growth and metabolism.
