AP BIOLOGY

Detailed explanation-1: -Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity.

Detailed explanation-2: -Chlorophyll is a molecule in chloroplasts that absorbs some of the energy in visible light. Energy from sunlight is absorbed and transferred along the thylakoid membrane. Water molecules are broken down and all oxygen is released.

Detailed explanation-3: -Carotenoids. Carotenoids are another key group of pigments that absorb violet and blue-green light (see spectrum graph above).

Detailed explanation-4: -Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color.
