Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle inside plant cells helps trap sunlight and produce food?
A
chloroplast
B
chromatin
C
cytoplasm
D
Golgi body
Explanation: 

Detailed explanation-1: -In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle-the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.

Detailed explanation-2: -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-3: -In eukaryotic cells these reactions occur in the organelle known as the chloroplast. In the chloroplast, chlorophyll is the pigment that absorbs the sunlight. Chlorophyll is typically packed into stacks of membranes (called grana); it is in the grana where some of the sunlight is absorbed.

Detailed explanation-4: -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-5: -Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy.
