Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Plants use energy from sunlight, water, and carbon dioxide to produce sugar. Which structure is found only in plant cells and helps plants capture energy from sunlight?
A
Vacoule
B
Nucleus
C
Cell membrane
D
Chloroplast
Explanation: 

Detailed explanation-1: -This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules. Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight.

Detailed explanation-2: -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.

Detailed explanation-3: -Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. It is like a solar panel that changes sunlight energy into electric energy. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.

Detailed explanation-4: -Inside the chloroplasts within leaves, light, water (H2O), and carbon dioxide (CO2) are transformed into energy and sugar (glucose). Using water, sunlight is converted into energy-storing molecules within the plant cells.
