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 found in plant cells?
A
to absorb light energy and manufacture food
B
to remove waste materials by active transport
C
to manufacture chemical energy from food
D
to control the shape of the cell
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 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-3: -However, plant cells and animal cells do not look exactly the same or have all of the same organelles, since they each have different needs. For example, plant cells contain chloroplasts since they need to perform photosynthesis, but animal cells do not.

Detailed explanation-4: -AI Recommended Answer: If the chloroplasts of a plant cell are damaged, it will be unable to make food for the cell.
