Detailed explanation-1: -Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color. During photosynthesis, chlorophyll absorbs energy from blue-and red-light waves, and reflects green-light waves, making the plant appear green.
Detailed explanation-2: -Chlorophyll’s job in a plant is to absorb light-usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
Detailed explanation-3: -Answer and Explanation: The plant cell organelle that uses light energy to produce sugar is the chloroplast.
Detailed explanation-4: -Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. It is like a solar panel that changes sunlight energy into electric energy. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.
