Answer 2

• Tissue level of organisation is shown by phylum cnidaria and ctenophora of kingdom animalia.

• Phylum Cnidaria is also called coelenterata .

• Example of coelerenterates are physalia, aurelia, gorgonia.

• Example of ctenophora is ctenoplana and pleurobrachia.

• They show tissue level of organisation, which means, the cells are grouped to form specific tissue.

• But those tissues do not get aggregated to form organs.

• The cells of the tissue perform specific function as a whole.

• This phlum shows division of labour. The functions of the organism are divided among its cells.

• The members of this phylum may be sessile or free living. They exhibits two forms called polyp and medusa.

• Some members of cnidarians exhibit alternation of generation called metagenesis.
