Question

Which of the following is not true about internal fertilization?

• A. The fusion of gametes occurs within the body
• B. Internal fertilisation occurs in amphibians
• C. Sperms are produced in large numbers
• D. In angiosperms, non-motile male gametes are carried to female gamete by pollen tubes

Answer 1

The correct option is B Internal fertilisation occurs in amphibians

In internal fertilization, fusion of gametes occurs within the body of the female. Sperms are generally produced in large numbers whereas the egg production is significantly reduced.

In amphibians, fertilisation is external and takes place in water.

The male gametes in flowering plants (angiosperms) are non-motile and are carried to the egg by pollen tubes.
