What part does chlorophyll play in photosynthesis?
A
It transports sugar and water to a plants leaves
B
It captures the sun’s energy
C
It drinks water from the soil the plant is in.
D
It breathes in the carbon dioxide.
Explanation: 

Detailed explanation-1: -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-2: -Chlorophyll is the green colour pigment found in the leaves of plants. Chlorophyll plays a major role in photosynthesis. It helps in trapping the light energy from sun and convert it into chemical energy.

Detailed explanation-3: -Chloroplasts Capture Sunlight When light strikes chlorophyll (or an accessory pigment) within the chloroplast, it energizes electrons within that molecule. These electrons jump up to higher energy levels; they have absorbed or captured, and now carry, that energy.

Detailed explanation-4: -Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.

Detailed explanation-5: -In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
