Assertion : Earthworm show cross fertilisation. Reason : Earthworm is hermaphrodite
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Earthworm are hermaphrodite which means both male and female reproductive organs are present in the same individual. Selffertilization will not occur because the testes mature earlier than the ovaries, Such a condition is called Protandry. Self fertilization will not occur also because of the relative position of opening of male and female reproductive organs(gonopores).

In female earthworms, how many ovaries are present
1 One pair of ovary
2 Two pair of ovary
3 Only testis are present
4 One ovary
Explanation:
In female earthworms, one pair of ovaries is found attached at intersegmental septum of \({\rm{1}}{{\rm{2}}^{{\rm{th}}}}\) and \({\rm{1}}{{\rm{3}}^{{\rm{th}}}}\) segements. Ovarian funnels are present beneath the ovaries which continue into the oviduct join together and open on the ventral side as a single female genital pore on the \({\rm{1}}{{\rm{4}}^{{\rm{th}}}}\) segment.

Which of the following structures in Pheretima is correctly matched with its functions?
1 Setae - defence against predators
2 Typhlosole - storage of extra nutrients
3 Clitellum -secretes cocoon
4 Gizzard-absorbs digested food
Explanation:
In earthworm, Clitellum secretes a mucus cocoon in which eggs are deposited. Cocoons are necessary to protect the eggs.
