GENERAL HISTOLOGY

Detailed explanation-1: -More number of mitochondria are found in actively dividing cells.

Detailed explanation-2: -For instance, cells that use a lot of energy tend to contain large numbers of mitochondria (the organelle responsible for harvesting energy from food). That’s why very active muscle cells are often full of mitochondria.

Detailed explanation-3: -Tissues and organs that need a lot of energy have large numbers of mitochondria in their cells. For example, liver cells and muscle cells contain a lot of mitochondria. Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells.

Detailed explanation-4: -Muscles require a large amount of energy to function. This is provided primarily by mitochondria in cells that consume a lot of energy. We therefore find more of these powerhouses of the cell in muscle cells than in other cell types with a lower metabolic rate.

Detailed explanation-5: -Nucleus: The nucleus is the most important organelle of the cell which controls all the cellular activity.
