Mitochondria are called the power house of the cell mainly because they:
AStore starch grains and lipid droplets
BProduce large numbers of ATP molecules
CSynthesise the green pigment chlorophyll
DMaintain the rigid shape of the cell
Answer & Solution
Correct answer: B. Produce large numbers of ATP molecules
1. Mitochondria are the main organelles of cellular respiration.
2. They produce a large number of ATP molecules, the energy currency of the cell.
3. Because of this ATP output they are called the power house of the cell.
4. Storage of starch is a chloroplast function, so that option is ruled out.
