CELL ORGANELLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The organelle that takes in sunlight and uses it for photosynthesis to give the cell energy. It is found only in plant cells.
A
Cytoplasm
B
Cell Wall
C
Chloroplast
D
Endoplasmic Reticulum
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 present in the cells of all green tissues of plants and algae. Chloroplasts are also found in photosynthetic tissues that do not appear green, such as the brown blades of giant kelp or the red leaves of certain plants.

Detailed explanation-3: -Chloroplasts contain green pigment called chlorophyll which helps in manufacture of food through the process of photosynthesis. Since, animals do not manufacture food so they do not need chloroplast. And hence, chloroplast is found only in plant cell.

Detailed explanation-4: -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-5: -Chloroplasts are organelles found in the broccoli’s cells, along with those of other plants and algae. They capture light energy and store it as fuel molecules in the plant’s tissues.
