Reproductive System in Human

Reproductive System in Human

Grade 9th

​Reproduction

• ​Reproduction is the process by which new organisms (offsprings) are generated. A living organism does not need reproduction to survive, but as a species, they need that for continuity and to ensure that they are not extinct. 

• Reproduction => cell division

Multiple Choice

The two male reproductive organs that produce most of the fluids that make up semen are called

• Testes & Epididymis
• Seminal Vesicle & Prostate
• Vas Deferens and Urethra
• Scrotum and Penis

Multiple Choice

In order to interact best with the acidic environment of the vagina, the pH of semen is 

• also acidic
• alkaline

Multiple Choice

The bulbourethral glands (Cowper's glands) produce

• gametes
• acidic substances

• lubricating mucus 
• sperm

​Spermatogenesis

​Sperm movement

​

​Sperms pathway in male reproductive organ

Open Ended

Type the sperms pathway from testes to outside

​Female Reproductive System

​

Multiple Choice

What do ovaries contain?

• Pre-matured egg cells.

• Sperm

• Carbon dioxide

• All of them

Multiple Choice

What does it happen in the uterus?

• The develop of sperm.

• The implantation and develop of a baby.

• The creation of ova.

• All of them

Multiple Choice

Where does the fertilization take place in?

• Cervix

• Fallopian tubes

• Vagina

• Endometrium

Multiple Choice

Where does the fertilized egg gets implanted in?

• Vagina

• Fallopian tubes

• Uterus

• All of them.

Multiple Choice

Female organ in which egg cells and sex hormones are produced

• Ovary

• Fallopian Tube

• Uterus

Multiple Choice

Passage that leads from the uterus to the outside of the body.

• Cervix

• Ovary

​Oogenesis

​Spermatogenesis vs Oogenesis

Multiple Choice

How many secondary spermatocytes are produced after the first round of meiosis?

• 1

• 2

• 4

Multiple Choice

The primary spermatocytes and the spermatogonia each contain 46 chromosomes.

• True

• False

Multiple Choice

Which of the following is a correct sequence of cells in spermatogenesis?

• spermatogonium -> secondary spermatocyte -> primary spermatocyte

• primary spermatocyte -> spermatogonium -> secondary spermatocyte

• spermatogonium -> primary spermatocyte -> secondary spermatocyte

• none of the above

Multiple Choice

Oogenesis results in the formation of:

• 1 ovum; 3 polar bodies
• 2 ova; 2 polar bodies
• 1 ovum; 3 secondary oocytes
• 4 ova

Multiple Choice

What do you call the process in which the ovary releases a mature egg cell?

• menstruation

• oogenesis

• ovulation

• fertilisation

Multiple Choice

Oogenesis is the process in the ovary that results in the

production of female gametes. Which statement about

oogenesis in humans is false?

• Oogenesis begins before birth

• The process of oogenesis is completed when the egg cell

  is penetrated by sperm

• Oogenesis continues throughout the life of individual

• In oogenesis, unequal cytokinesis results in one single

  large daughter cell, which goes on to form the egg
