Which process describes the creation of an egg (ovum) in the ovaries?

Oogenesis, unlike spermatogenesis, is a continuous process that occurs throughout a woman's life.

How many functional eggs are typically produced from each cell that undergoes meiosis during oogenesis?

Match each term with its description:

Which of the following characteristics describes an ovum?

The ______ and corona radiata are layers covering the ovum.

Match each characteristic with either sperm or ovum:

What is the primary advantage of sexual reproduction compared to asexual reproduction?

Sexuality and reproduction are synonymous terms in biology.

What term describes organisms, including humans, that develop inside the mother's body?

Male sex hormones, such as testosterone, are collectively known as ______.

Match the following components with their roles in the male reproductive system:

What is the function of Cowper's glands in the male reproductive system?

The primary function of the uterus is to produce eggs.

What is the collective term for the labia majora and minora, including the clitoris?

The ______ cycle refers to the changes that occur in the uterus to prepare for implantation.

Match each term with its appropriate definition or location:

How does the lack of genetic diversity in asexually reproducing species affect their ability to survive in changing environments?

What is the role of the acrosome in a sperm cell, and why is it essential for fertilization?

Explain how the structure of the seminiferous tubules in the testicles supports the process of spermatogenesis.

How do the secretions from the seminal vesicles contribute to the survival and function of sperm cells?

Describe the roles of the prostate gland and the Cowper's glands in facilitating successful fertilization.

What are the key differences between spermatogenesis and oogenesis in terms of timing and products?

Explain how the structure of the penis, including the corpora cavernosa and corpus spongiosum, enables it to perform its reproductive function.

What is the significance of the scrotum's location outside the body for sperm production?

Describe the relationship between the ovarian cycle and the uterine cycle, and their combined purpose in the menstrual cycle.

How does the epididymis contribute to the maturation and storage of sperm?

What are the primary differences between asexual and sexual reproduction, and what are the evolutionary implications of these differences?

Explain the role of meiosis in both spermatogenesis and oogenesis, and why it is essential for sexual reproduction.

How does the structure of the egg, including the zona pellucida and corona radiata, support the process of fertilization?

Describe the function of the vas deferens in the male reproductive system, and explain what happens during a vasectomy.

How do hormones, such as androgens, regulate the development and function of the male reproductive system?

What adaptations does sperm have that allow them to reach and fertilize an egg?

What are the advantages of sexual reproduction compared to asexual reproduction?

How do the male and female reproductive systems ensure that gametes (sperm and egg) meet for fertilization to occur?

Describe the process of spermatogenesis, including the roles of spermatogonia, meiosis, and maturation.

How is oogenesis different from spermatogenesis in terms of the number of gametes produced and the timing of the process?
