In human beings, a single matured egg is released into the____________ by one of the ovaries every month.

A
uterus

B
oviduct

C
testes

D
None of the above

Solution

The egg is matured and released by one of the ovaries into the oviduct every month in human beings.
A uterus is a part where the baby develops.
Testes are found in males and they produce sperms.
Therefore, the correct option is B.
Question 2
1 / -0

What purpose does the tail in a sperm serve?

A
To swim to the egg

B
To provide direction

C
To carry the genetic material

D
To provide nutrition

Solution

Answer:
The flagellum, also called the sperm "tail," is a slender lash-like appendage that protrudes from the cell body. By beating their tails, sperm cells swim to the female reproductive cell (oocyte) and fertilise it.
The sperm tail is made of protein fibers that contract on alternative sides, giving a characteristic wave like movement that drives the sperm through the seminal fluid, which also supplies additional energy.
The tail gives the sperm cell movement. It whips and undulates so that the cell can travel to the egg.
Question 3
1 / -0

What is the purpose of the reproductive parts in animals?

A
To facilitate the fusion of gametes

B
To produce gametes

C
To destroy gametes after fertilization

D
Both A and B

Solution

The main purpose of the reproductive parts in animals is to produce gametes and to facilitate the fusion of gametes so that reproduction can take place.
The correct option is C.
Question 4
1 / -0

Fill in the blank:

The parts of a sperm include a head, a ____________, and a tail.

A
middle piece

B
body

C
centrepiece

D
neck
Solution
- Apart from the head and the tail, a sperm consists of a middle piece.
- The head of the sperm contains the nucleus, the middlepiece is packed with mitochondria to provide energy for swimming and the tail moves like a propeller.
The correct option is A.
Question 5
1 / -0

Fill in the blank:
When sperms come in contact with an egg, _______________ of the sperms may fuse with the egg.

A
all

B
two

C
three

D
one

Solution

Millions of sperms are released by a male to fuse with the egg produced by a female, but only one of them finally fuses with the egg to form a zygote.
So, the correct option is D.
Question 6
1 / -0

The fusion of male and female gametes results in the formation of:

A
Zygote

B
Embryo

C
Sperm

D
Egg

Solution

The fusion of male and female gamete results in the formation of a zygote.
The zygote develops to form an embryo.
The correct answer is option A.
Question 7
1 / -0

What is the function of the jelly on the eggs laid by frogs?

A
To hold the eggs together

B
To provide protection to the eggs

C
Both A and B

D
None of the above

Solution

A layer of jelly holds the eggs together and provides protection to the eggs as the eggs are exposed to water movement, wind and rainfall.
So, the correct option is C.
Question 8
1 / -0

How do the sperms reach the egg during external fertilization in water bodies?

A
Eggs float to the sperms

B
Sperms randomly swim to the eggs using tail

C
Animals carry sperms to the egg

D
None of the above

Solution

In external fertilization, as the eggs are laid, the male deposits sperms over them. Each sperm swims randomly in water with the help of its long tail. The sperms come in contact with the eggs and this results in fertilisation.

So, the correct option is B
Question 9
1 / -0

Fill in the blank:
Unlike hen's egg, frog's egg is not covered by a ________ and it is comparatively very delicate.

A

Solution

Hen's eggs are covered by a shell while that of frogs are covered in jelly.
The correct option is A.
Question 10
1 / -0

What type of fertilization takes place in frog and fish?

A
External fertilization

B
In vitro fertilization

C
Internal fertilization

D
In vivo fertilization

Solution

The type of fertilization in which the fusion of a male and female gametes takes place outside the body of the female is called external fertilization. It is very common in aquatic animals such as fish, frogs, etc.
