1.
A major male sex organ that produces and stores sperm.
Correct Answer
B. Testicle
Explanation
The testicle is the correct answer because it is a major male sex organ that produces and stores sperm. The testicles are responsible for the production of sperm cells, which are necessary for reproduction. They also produce testosterone, the primary male sex hormone. The testicles are located in the scrotum and are essential for male fertility and sexual function.
2.
A chemical or hormone produced by the testes that causes bodily changes during male puberty.
Correct Answer
B. Progesterone
Explanation
Progesterone is a hormone produced by the ovaries in females, not the testes. It plays a crucial role in regulating the menstrual cycle and preparing the uterus for pregnancy. It is not responsible for causing bodily changes during male puberty. Therefore, the correct answer is progesterone.
3.
A set of coiled tubes that connect to the vas deferens.
Correct Answer
B. Epididymis
Explanation
The epididymis is a set of coiled tubes that connect to the vas deferens. It is located on top of each testicle and serves as a storage and maturation site for sperm. Sperm produced in the testes travel through the epididymis, where they gain the ability to swim and fertilize an egg. From the epididymis, the sperm then continue their journey through the vas deferens and eventually reach the urethra for ejaculation. Therefore, the epididymis is the correct answer as it accurately describes the function and location of this structure.
4.
A muscular tube that transports sperm-filled semen.
Correct Answer
C. Vas deferens
Explanation
The vas deferens is a muscular tube that transports sperm-filled semen. It is responsible for carrying sperm from the epididymis to the urethra during ejaculation. The vas deferens plays a crucial role in the male reproductive system by allowing the sperm to be transported and released during sexual intercourse.
5.
Tiny male cell that unites with the female ovum to form a fertilized egg or zygote.
Correct Answer
A. Sperm
Explanation
A sperm is a tiny male cell that combines with the female ovum during fertilization to form a zygote or fertilized egg. Sperm is produced in the testes and stored in the scrotum. It is released during ejaculation and travels through the female reproductive system to reach the ovum for fertilization.
6.
A fluid that contains millions of sperm.
Correct Answer
C. Semen
Explanation
Semen is the correct answer because it is a fluid that contains millions of sperm. It is the reproductive fluid produced by males and is ejaculated during sexual intercourse. Semen provides a suitable environment for the sperm to survive and swim towards the egg for fertilization.
7.
The sac that holds the testes.
Correct Answer
A. Scrotum
Explanation
The scrotum is a pouch of skin that holds and protects the testes. It is located outside the body, hanging between the legs. The scrotum helps to regulate the temperature of the testes, keeping them slightly cooler than the rest of the body, which is important for the production of healthy sperm. Additionally, the scrotum can contract or relax to adjust the position of the testes, depending on factors such as temperature or sexual arousal.
8.
A process in which sperm laden semen leaves the male body.
Correct Answer
C. Ejaculation
Explanation
Ejaculation is the correct answer because it refers to the process in which sperm laden semen is expelled from the male body. Ovulation is the release of an egg from the ovary in females, while gestation is the period of pregnancy in which the fetus develops.
9.
These are responsible for carrying sperm filled semen from the male to the female's vagina.
Correct Answer
A. Penis and urethra
Explanation
The penis and urethra are responsible for carrying sperm-filled semen from the male to the female's vagina. The penis is the male reproductive organ that becomes erect during sexual arousal and allows for the insertion into the vagina. The urethra, on the other hand, is the tube that runs through the penis and serves as a passage for both urine and semen. Together, these structures enable the transfer of sperm from the male to the female during sexual intercourse.
10.
A gland that makes some of the parts of semen.
Correct Answer
C. Prostate
Explanation
The prostate gland is responsible for producing some of the components of semen. It is a small gland located below the bladder and in front of the rectum in males. The prostate gland secretes a fluid that helps nourish and protect sperm, contributing to the overall composition of semen.
