Which cell organelles are present in greater numbers in cells with high energy demands?
a. nuclei
b. mitochondria
c. lysosomes
d. golgi apparatus

The correct answer would be option B.

Explanation:

Mitochondrion, also known as energy house of the cell, is a cell organelle mainly involved in the production of cellular energy, that is, ATP.

It is a double membrane-bound cell organelle which contains majority of enzymes involved in cellular respiration including ATP synthase.

All the metabolic processes involved in cellular respiration apart from glycolysis take place in mitochondria only. For example, Krebs cycle, oxidative phosphorylation, electron transport chain, chemiosmosis, et cetera.

Thus, mitochondria would be present in greater numbers in the cells which have high energy demands.
