what does photosynthesis form in a leaf first?
Answers
the process plants use to produce food is photosynthesis.
the answer is food (food in the presence of starch=sugar) and oxygen.
The early stage of photosynthesis is composed of light-dependent activities. In the first phase, light energy is converted to the chemical energies ATP and NADPH (reducing power).
What is photosynthesis?A system of interconnected internal membranes called thylakoid membranes in a chloroplast performs the light activities of photosynthesis.
Each thylakoid membrane contains a large number of protein molecules as well as chlorophyll molecules. The term "photosystem" refers to collections of chlorophyll molecules.
Chlorophyll pigments are used by plants to absorb light energy, transform it into electrons, and then convey those electrons along a protein chain in the thylakoid membrane.
Therefore, light energy is converted to the chemical energies ATP and NADPH (reducing power).
