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: -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-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: -More specifically, chlorophyll resides in the thylakoid membranes. The chlorophyll absorbs energy from sunlight, and it is this energy that drives the synthesis of food molecules in the chloroplast.
