Reproduction and Fertilization Quiz

What is fertilization?

• The process by which a zygote divides to form gametes.

• The union of haploid gametes to form a diploid cell.

• The division of a zygote into multiple cells.

• The process by which an ovum develops into an embryo.

What is the significance of fertilization in sexual reproduction?

• It increases genetic diversity.

• It initiates embryonic development.

• It restores the species number of chromosomes.

• It produces gametes for reproduction.

What is the resulting cell called after the union of sperm and ovum?

• Embryo

• Gamete

• Zygote

• Blastocyst

What is the main difference in motility between sperm and ova?

• Sperm are immobile, while ova can move on their own.

• Both sperm and ova are mobile and can move on their own.

• Sperm can move due to flagella, while ova cannot move on their own.

• Both sperm and ova are immobile and cannot move on their own.

Which is generally larger in size?

• Sperm

• Ova

• Both are the same size

• The size varies and cannot be determined

What are the two types of fertilization?

• Internal and External Germination

• External and Internal Fertilization

• External and Internal Pollination

• Internal Germination and External Fertilization

Where does external fertilization usually take place in animals?

• Inside the female's body

• Outside the female's body in water

• On land

• In the air

Which animals are most likely to use external fertilization?

• Most mammals and birds

• Most fish and many amphibians

• Reptiles and insects

• Primates and marsupials

What is a disadvantage of external fertilization?

• Sperm always meets the egg

• Eggs are protected from predators

• Temperature or pH change cannot kill them

• Eggs or developing offspring may get eaten by other animals

Why do animals that use external fertilization release many eggs and sperm?

• To increase the chances of fertilization

• Because it is easier to produce them in large numbers

• To feed other animals

• To create a display for attracting mates
