Leaf
C
Stem
D
None of the above
Explanation: 

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: -Leaves are the main (but not only) organ responsible for turning sunlight into food. The green pigment found in most leaves absorbs sunlight, which is one of the important ingredients in the food-making process. This process is called photosynthesis. During photosynthesis, chlorophyll captures the energy of sunlight.

Detailed explanation-3: -Answer: chlorophyll is a only part in a leaf which absorbs light.

Detailed explanation-4: -Absorbing light energy Light absorption happens in the palisade mesophyll tissue of the leaf. Palisade cells are column-shaped and packed with many chloroplasts . They are arranged closely together so that a lot of light energy can be absorbed.
