Why is the cytoplasm of sperm cells very reduced, Biology

Assignment Help:

Why is the cytoplasm of sperm cells very reduced? Why do mitochondria of sperm cells concentrate in the base of the flagellum?

The decreased cytoplasm of sperm cells reduces the cell weight and gives a more hydrodynamic shape for the locomotion in fluids.

The high concentration of mitochondria at the base of the flagellum of the sperm cell is essential for the energetic supply of the flagellum (for it to beat and move the sperm cell).
