Chapter 4: Problem 38

For each of the following questions, four choices have been provided. Select the correct alternatives. The part of sperm that contains mitochondria (a) Tail (b) Acrosome (c) Middle piece (d) Head

Short Answer

Expert verified
Answer: (c) Middle piece

Step by step solution

01

Eliminating options that do not contain mitochondria

Mitochondria are organelles that provide energy in cells through cellular respiration. We can eliminate options where mitochondria are not found. The acrosome contains enzymes that help the sperm to penetrate the egg and fuse with it, thus it does not contain mitochondria. The head of the sperm contains the male genetic material, also without mitochondria. This leaves the tail and the middle piece as potential options.
02

Identifying the correct part of the sperm containing mitochondria

The tail of the sperm helps it to swim towards the egg, however, it does not contain mitochondria. The middle piece of the sperm contains several mitochondria wrapped around the outer edge, which provide the energy required for the sperm's movement and function. Hence, the correct answer is the middle piece.
03

Answer

The part of the sperm cell that contains mitochondria is (c) Middle piece.
