Which of these is a plant organ responsible for absorbing light energy to make food?
A
leaf
B
stem
C
root
D
flower
Explanation: 

Detailed explanation-1: -There are many different types of pigments in nature, but chlorophyll is unique in its ability to enable plants to absorb the energy they need to build tissues. Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells. This is where photosynthesis takes place.

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: -Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color.

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.
