Question

The size of mitochondria in plant cell is

• A. 0.01-1.0 $\mu$m long
• B. 1-4 $\mu$m long
• C. 2-4 $\mu$m long
• D. 3.0-4.0 $\mu$m long

Answer 1

The correct option is B 1-4 $\mu$m long

Mitochondrion

Mitochondrion is a double membranous cell organelle found in the eukaryotic cells.

More than one mitochondria are found in the cells and their number varies depending upon the physiological activity of the cell.

It shaped is cylindriacl or sausage -like with the following dimensions:

• Diameter: 0.2-1.0 $\mu m$ (average 0.5 $\mu m$)
• Length :1.0-4.1 $\mu m$

It is the site of cellular respiration in the cell in which the energy is obtained from the food and converted in the much easily usable form, that is ATP molecules.

Final answer: c. 1-4 $\mu$m long
