Question

In terms of the shape and size of mitochondria, a considerable degree of variability is observed. The number of mitochondria per cell is variable depending on the

• A. Physiological activity of the cells
• B. Biochemical activity of the cells
• C. All of the above
• D. Morphology of the cells

Answer 1

The correct option is A Physiological activity of the cells

Number of mitochondria in a cell

Mitochondria are the cell organelles that are responsible for energy production.

These are dark brown sac-like organelles bounded by a double membrane.

They produce chemical energy in the form of $ATP$ by breaking down the energy-producing molecules like glucose.

Due to the fact that they produce energy, mitochondria are also known as the ‘Powerhouse of the cell’.

The number of mitochondria in a cell varies depending on the energy required by that cell or the physiological activity of that cell.

Hard working active cells have more number of mitochondria.

Final answer

(C) Physiological activity of the cells
