Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Chloroplasts in plant cells allow the plant to perform a function that animal cells cannot do. What is the main function of the chloroplasts?
A
manufacture chemical energy from food
B
remove waste materials by active transport
C
absorb light energy and make food
D
control the shape of the cell
Explanation: 

Detailed explanation-1: -The chloroplast’s job is to carry out a process called photosynthesis. In photosynthesis, light energy is collected and used to build sugars from carbon dioxide.

Detailed explanation-2: -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-3: -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].

Detailed explanation-4: -Chloroplasts are required for producing chlorophyll from sunlight. Animals are incapable of performing photosynthesis because they lack these structures; only plant cells and certain protists contain chloroplasts.

Detailed explanation-5: -Functions of Chloroplast Absorbs light energy and converts it into chemical energy. Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and is used for the synthesis of food in all green plants. Produces NADPH and molecular oxygen (O2) by photolysis of water.
