What is the main function of a sperm cell?

To deliver male DNA to the female egg for fertilization.

What part of the sperm cell contains genetic information?

The nucleus.

What is the main component of the sperm tail?

Microtubules arranged in a flagellum.

What is the acrosome?

A cap-like structure at the head of the sperm that contains enzymes.

What cell organelle is abundant in the midpiece of the sperm?

Mitochondria.

What is the primary role of the enzymes in the acrosome?

To help the sperm penetrate the egg.

How is sperm mobility achieved?

Through the movement of the flagellum or tail.

What part of the sperm cell is primarily responsible for energy production?

The midpiece containing mitochondria.

What is the size comparison of a sperm cell to other human cells?

Sperm cells are among the smallest human cells.

What is the lifespan of a sperm cell once inside the female body?

Up to five days.

Why is the streamlined shape of sperm cells important?

It aids in efficient swimming towards the egg.

What gene is thought to be essential for sperm motility?

The CATSPER gene.

How many chromosomes does a normal human sperm cell contain?

23 chromosomes.

What is the significance of the sperm cell being haploid?

It contains half the number of chromosomes, essential for forming a diploid zygote after fertilization.

What happens during the capacitation of sperm?

Sperm undergo physiological changes that increase their motility and ability to penetrate the egg.
