Which part of a plant takes in energy from the sun?
A
Flowers
B
Roots
C
Leaves
D
Veins
Explanation: 

Detailed explanation-1: -Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy. Not all the light energy from the sun is absorbed. Sunlight has many different colors in it. Chlorophyll usually absorbs red and blue light from the sun and reflects green light.

Detailed explanation-2: -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-3: -Leaves contain chlorophyll and are the sites of photosynthesis in plants. Their broad, flattened surfaces gather energy from sunlight while apertures on the their undersides bring in carbon dioxide and release oxygen.

Detailed explanation-4: -They capture the sun’s energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis. Leaves usually have a large surface so they can collect the most sunlight.

Detailed explanation-5: -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.
