Biology Quiz on Reproductive System

This state of adolescence is called –––––––.

• Independence

• Maturity

• Puberty

• Menstruation

Answer explanation

This state of adolescence is called puberty, which refers to the physical and hormonal changes that occur as a person transitions from childhood to adulthood, marking the onset of reproductive capability.

The tissue that provides nourishment to the embryo in the uterus is-

• Villi

• Oviduct

• Fallopian tube

• Placenta

Answer explanation

The placenta is the tissue that forms in the uterus during pregnancy, providing essential nutrients and oxygen to the developing embryo while also removing waste products. It is crucial for the embryo's growth and development.

––––– is the name of the age during which the reproductive organs of human males and females become functional, the gonads start producing gametes and sex hormones, and become mature towards human sex.

• Sexual reproduction

• Gametes

• Parthenogenesis

• Adolescence

Answer explanation

Adolescence is the developmental stage when human reproductive organs mature, gonads produce gametes and sex hormones, marking the transition to sexual maturity. This aligns with the question's description.

Which process of fusion sperm and ova results in the formation of a single structure called zygote?

• Fragmentation

• Fertilization

• Tissue culture

• Sexual reproduction

Answer explanation

The process of fertilization involves the fusion of sperm and ova, leading to the formation of a zygote, which is the first stage of development in sexual reproduction.

Sperms are produced in ––––.

• Ureter

• Testis

• Prostate gland

• Scrotum

Answer explanation

Sperms are produced in the testis, which is the male reproductive organ responsible for sperm production and hormone secretion. The ureter and prostate gland have different functions, while the scrotum houses the testis.

Why do men have testicles outside the body?

• Due to presence of spermatheca

• Sperm formation requires a lower temperature than normal body temperature.

• Sperm formation requires higher temperature than normal body temperature.

• Due to the special tissues found in parts of the stomach.

Answer explanation

Sperm formation requires a lower temperature than normal body temperature, which is why testicles are located outside the body. This cooler environment is essential for optimal sperm production and health.

........ serves as a nutritive tissue for growing embryo.

• Ovule

• Ovary

• Endosperm

• zygote

Answer explanation

The endosperm is the nutritive tissue that provides essential nutrients to the growing embryo in seeds, making it the correct answer. The ovule and ovary are parts of the reproductive structure, while the zygote is the fertilized egg.

Name the tube that originates from male testis and carries sperm into the body?

• Epididymis

• Seminiferous tubules

• Urethra

• Vas deferens

Answer explanation

The vas deferens is the tube that carries sperm from the epididymis into the body, specifically to the urethra for ejaculation. The other options do not serve this function.

Sperms are temporarily stored in the ……… .

• Vas efferens

• Epididymis

• Bladder

• Vas deferens

Answer explanation

Sperms are temporarily stored in the epididymis, a coiled tube located at the back of each testis. This structure allows for the maturation and storage of sperm before they are transported through the vas deferens.

Which of the following is a male reproductive part in human beings?

• Vas deferens

• Uterus

• Fallopian tube

• Ovary

Answer explanation

The vas deferens is a male reproductive part responsible for transporting sperm from the testes. In contrast, the uterus, fallopian tubes, and ovaries are female reproductive structures.
