Reproduction In Humans — Practice Quiz

Sperms

Step 1: In sexual reproduction, males and females produce special reproductive cells called gametes. Step 2: The male gametes are called sperms (or sperm cells). Step 3: The female gametes are called eggs (or ova). Step 4: A zygote is formed after a sperm fuses with an egg — it is not a gamete itself. Step 5: An embryo is a later stage of development after the zygote. So sperms is the correct answer.

Ovaries

Step 1: The female reproductive system has several organs, each with a specific function. Step 2: The ovaries are two whitish oval bodies located in the lower abdomen. Step 3: The function of the ovaries is to produce eggs (ova) — one egg is produced each month alternately by each ovary. Step 4: The uterus is where the embryo grows and develops. Step 5: Fallopian tubes carry the egg from the ovary to the uterus, and the vagina is the birth canal. So ovaries is the correct answer.

The embryo grows and develops here

Step 1: The uterus is a hollow, inverted pear-shaped muscular organ found in the pelvic cavity. Step 2: Its main function is to provide a safe place for the embryo to grow and develop during pregnancy. Step 3: Eggs are produced in the ovaries, not the uterus. Step 4: Fertilisation takes place in the fallopian tubes (oviducts), not the uterus. Step 5: Sperms are not stored in the uterus. So the correct answer is that the embryo grows and develops in the uterus.

Testes

Step 1: The male reproductive system has several organs. Step 2: Sperms are produced in the testes, which are located outside the abdominal cavity in a sac called the scrotum. Step 3: The scrotum is just a protective sac that holds the testes — it does not produce sperms. Step 4: The seminal vesicles produce a fluid that helps transport sperms. Step 5: The prostate gland produces an alkaline secretion added to semen. So testes is the correct answer.
