  1. Male gamete

  2. Female gamete

  3. Both male and female gamete

  4. None of these

C Correct answer
Explanation

A Barr body is the inactive X chromosome in female somatic cells. Since women have two X chromosomes, one is inactivated in each cell. Men (XY) and gametes (sperm/ovum) do not have Barr bodies.

Multiple choice

The joining of an egg cell and a sperm cell is called

  1. gestation

  2. adaption

  3. asexual

  4. fertilization
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Fertilization is the specific term for the union of a sperm cell and an egg cell to form a zygote. This is a fundamental step in sexual reproduction.

Multiple choice

What is meant by 'in vitro fertilisation'

  1. Asexual reproduction

  2. Embryo transfer

  3. Artificial insemination

  4. Process by which an egg is fertilised by a sperm 'in glass'

D Correct answer
Explanation

In vitro fertilization (IVF) is a medical procedure where an egg is combined with sperm outside the body, literally 'in glass' (petri dish).

Multiple choice

  1. more eggs means they are more likely to be fertilized

  2. more eggs increases the chances some offsprings will survive

  3. single laying eggs are actually more advantages

  4. there is no survival purpose to laying hundreds of eggs

What is acrosomal reaction?

  1. Contact of sperms with egg

  2. Digestion of zona pellucida

  3. Disintegration of acrosome

  4. Contact of acrosome and nucleus of egg
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The acrosomal reaction involves the release of enzymes from the sperm's acrosome, which digest the zona pellucida of the egg to allow fertilization.

Multiple choice

What is the primary function of the male gamete in sexual reproduction?

  1. Providing Nutrients

  2. Fertilizing the Egg

  3. Producing Energy

  4. Protecting the Embryo
Reveal answer Fill a bubble to check yourself
