Cnidarians and ctenophores share which of the following characteristics?
1 Tissue level of organisation
2 Metagenesis
3 Cnidocytes
4 Comb plates
Explanation:
Both cnidarians and ctenophores are diploblastic with tissue level of organisation. Metagenesis and cnidocytes are absent in ctenophores. Comb plates are absent in cnidarians.

Metagenesis refers to
1 Occurrence of a drastic change in form during post embryonic development
2 Presence of a segmented body and parthenogenetic mode of reproduction
3 Presence of different morphic forms
4 Alternation of generation between asexual and sexual phases of an organism
Explanation:
The alternation between the sexual and the asexual phase within the same species during the life cycle of a plant or animal. Example. Metagenesis in Obelia.

Assertion : Coelenterates are diploblastic. Reason : Coelenterates contain mesoglea in between ectoderm and endoderm.
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:
Coelentrates are diploblastic animals. Endoderm and ectoderm are the two germinal layers present and in between them an undifferentiated layer called mesoglea is present.

Statement A : Cnidarians are a great nuisance to the humans swimming in the sea Statement B : They can sting and even paralyse people swimming in sea
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Cnidarians like Jellyfish are the most frequent stingers in sea waters. They are a nuisance as they sting people taking a bath or swimming in the sea.Their stings penetrate human skin and introduce the toxins which produce the pain and even cause paralysis. .
