Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which plant cell organelle converts sunlight into food?
A
Mitochondria
B
Lysosome
C
Chloroplast
D
Cell Wall
Explanation: 

Detailed explanation-1: -Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.

Detailed explanation-2: -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-3: -The cell part that converts food into energy is the mitochondria. The mitochondria is an organelle enclosed by two membranes.

Detailed explanation-4: -The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light-dependent reaction. The chlorophyll absorbs energy from the light waves, which is converted into chemical energy in the form of the molecules ATP and NADPH.

Detailed explanation-5: -Chloroplasts produce energy through photosynthesis and oxygen-release processes, which sustain plant growth and crop yield. As such, chloroplasts are responsible for the biosynthesis of active compounds such as amino acids, phytohormones, nucleotides, vitamins, lipids, and secondary metabolites [9].
