السؤال 77

A sperm cell needs ATP to power movement. Which structural description identifies the region adapted to provide much of this ATP?

A cellulose wall around the head
A chloroplast-rich tail tip
Many mitochondria in the midpieceالإجابة الصحيحة
A large vacuole beside the nucleus

الشرح

Many mitochondria are concentrated in the midpiece, where their ATP production can support movement of the nearby tail. The acrosome is located at the head and has a different role, so it is not the main mitochondrial region.
