The testicles are held in

  1. Cowper's glands

  2. Ductus deferens

  3. Prostate gland

  4. Scrotum sac

D Correct answer
Explanation

The scrotum is a sac that hangs under the penis and holds the testes. It is divided internally into two halves by a membrane; each half containing a testis. It has an outer layer of thin, wrinkled skin over a layer of tissue which contains muscle.

Multiple choice

  1. male gametes

  2. female gametes

  3. Both 1 and 2

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Germ cells are the reproductive cells, which include both male gametes (sperm/pollen) and female gametes (eggs/ovules).

Multiple choice

Which of the following statements is/are incorrect?

a. Male gamete in animals is called sperm. b. Female gamete in animals is called ova. c. The cell which is formed by the fusion of the male and female gametes is called embryo.

  1. a, b and c

  2. a and b

  3. only a

  4. only b

  5. only c
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

This is the correct answer as this statement is incorrect. The cell which is formed by the fusion of the male and female gametes is called zygote. The zygote grows and develops to grow into a new baby and this baby in the early stages of its development is called an embryo.

Multiple choice

Which of the following statements is/are correct?

a. Testes make the male sex cells as well as the male sex hormone. b. The testes of a man lie in a small muscular pouch called the vas deferens outside the abdominal cavity. c. The sperms formed in testes come out and go into the tube called penis.

  1. a only

  2. b only

  3. c only

  4. a and b

  5. a, b and c

A Correct answer
Explanation

This is the correct answer as this statement is correct. Testes make the male sex cells called the sperm as well as the male sex hormone called testosterone.

Multiple choice

Amphimixis is

  1. fusion of sperm with egg

  2. fusion of pronucleus of sperm with egg

  3. not a kind of fusion

  4. fusion of diploid cells

  5. -
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

It is a sexual reproduction involving the fusion of two different gametes to form a zygote.

Multiple choice

Double fertilisation means the fusion of

  1. one male gamete with the egg and the other with the antipodal cell

  2. one male gamete with the egg and the other with the secondary nucleus

  3. one male gamete with the egg and the other with the synergids

  4. two male gametes with the egg

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Double fertilisation means the fusion of one male gamete with the egg and the other with the antipodal cell.

Multiple choice

The formation of egg and sperm is affected by

  1. LH

  2. FSH

  3. TSH

  4. MSH

  5. -
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

FSH is synthesised and secreted by gonadotropic cells of the anterior pituitary gland. It regulates the development, growth, pubertal maturation and reproductive processes of the body.

Multiple choice

Sertoli cells help in

  1. maturation of eggs

  2. maturation of sperms

  3. enzyme production

  4. ovulation

  5. -
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sertoli cells are somatic around which spermatids develop in the tubules of the testis.

Multiple choice

Maturation of sperm without penetration is called

  1. spermatogenesis

  2. spermiogenesis

  3. capacitation

  4. spermatid

  5. -
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Capacitation is a functional maturation of the spermatozoon. The changes take place through the sperm cell membrane in which it may be that receptors are made available through the removal of a glycoprotein layer.

Multiple choice

Secretions of epididymis, vas deferens, seminal vesicle and prostate are essential for

  1. only maturation of sperms

  2. maturation and motility of sperms

  3. only motility of sperms

  4. storage of sperms

  5. to kill the sperms
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sperms released from the seminiferous tubules are transported by the accessory ducts. Secretions of epididymis, vas deferens, seminal vesicle and prostate are essential for maturation and motility of sperms.
