DENDROLOGY

Detailed explanation-1: -Chloroplasts and photosynthetic bacteria obtain high-energy electrons by means of photosystems that capture the electrons that are excited when sunlight is absorbed by chlorophyll molecules.

Detailed explanation-2: -Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.

Detailed explanation-3: -This energy is stored in the ATP molecule and it is subsequently used to synthesize carbohydrate in the dark phase of photosynthesis.

Detailed explanation-4: -Within these cells, organelles called chloroplasts use the carbon dioxide and water to carry out photosynthesis.
