Weekly Quiz Competition

Question 1
1 / -0

One of the minute cell which separates from the animal egg during maturation is known as

A
Primary spermatogonia

B
Secondary oogonia

C
Primary oogonia

D
Polar bodies

Solution

During maturation phase, the primary oocyte undergoes meiosis I Producing two haploid cells (n) the larger one is secondary oocyte and the smaller one is first polar body, meiosis II of secondary oocyte result in the formation of functional egg or ovum and a second polar body.
Question 2
1 / -0

Assertion: A chemical substance fertilizin is present in eggs.

Reason: It helps in maturation of embryo after fertilization.

A
If both Assertion and Reason are true and Reason is the correct explanation for Assertion

B
If both Assertion and Reason are true and Reason is not the correct explanation for Assertion

C
If Assertion is true and Reason is false

D
If Assertion is false and Reason is true

Solution

Fertilizin (Lilli, 1919) a chemical compound presents in eggs. It is glycoprotein which is composed of different kinds of amino acids and monosaccharides (glucose, fructose and galactose) according to the species. Due to the presence of fertilizin, the eggs are supposed to attract the sperms which contain a particular type of antifertilizin.
Question 3
1 / -0

The final event in the process of fertilization is

A
amphimixis

B
egg activation

C
fusion of gametes

D
organizational change in egg cytoplasm

Solution

Entry of sperm stimulates the secondary oocyte to start the suspended meiosis-II resulting in the formation of one ootid and 2-3 polar bodies. Ootid changes to become ovum, male and female pronuclei get mixed up. The process is called amphimixis.
Question 4
1 / -0

To oogamy, fertilization involves :

A
a small non-motile female gamete and a large motile male gamete

B
a large non-motile female gamete and a small motile male gamete

C
a large non-motile female gamete and a small non-motile male gamete

D
a large motile female gamete and a small non-motile male gamete

Solution

In oogamous type of sexual reproduction, the female gamete (ovum/egg) is big, passive while male gametes (spermatozoids) are smaller, active and motile
Question 5
1 / -0

Termination of gastrulation is marked by

A
Obliteration of archenteron

B
Closure of neural tube

C
Obliteration of blastocoel

D
Closure of blastopore

Solution

By the end of gastrulation, blastocoels will be Obliterated a and Neural tube will be developed.
Question 6
1 / -0

Which is the correct sequence in the development of man?

A
Fertilization, zygote, cleavage, morula, blastula, gastrula

B
Zygote, morula, blastula, differentiation

C
Fertilization, cleavage, gastrula, morula, blastula

D
Cleavage, zygote, blastula, morula, gastrula

Solution

The correct sequence in the development of man is as follows:
Fertilization > zygote > cleavage > morula > blastula > gastrula.
Question 7
1 / -0

Type of cleavage in fertilized egg depends on

A
Amount of yolk

B
Number of cells

C
Number of mitochondria in the sperm

D
Number of testes

Solution

The rate and nature of cleavage are much affected by factors like light, temperature, Moderate, amount of yolk, cytoplasmic organization, mitosis etc.
Question 8
1 / -0

The blastomeres in the blastocyst are arranged into an outer layer called

A
tonoplast

B
blastoplast

C
trophoblast

D
vitelline membrane

Solution

Trophoblasts are cells forming the outer layer of a blastocyst, which provide nutrients to the embryo and develop into a large part of the placenta.
