Question

explain body plan of phylum Coelenterata

Answer 1

Hello mate.

Thanks for asking this question.

Your answer is =>

The body plan of all Coelenterata animals is Radially Symmetric.

We consider them as when they are used for experiment , their body can be radially cut into equal and identical pieces.

the several planes can be passed through the common point on the body of coelenterates and hence these are considered as Radially Symmetrical animals.

# Coelenterates are one of the simplest among the most complex animals.

# Body of coelenterates contains two germinal layers called as Epidermis and Gastrodermis.

# Between these two layers , there is a non-cellular Jelly like substance which is called as MESOGLEA or Mesohyle.

# Few of the coelenterates are assymetrical during their Larval stages.

# Body of Coelenterates contains Thread like Tentacles around the mouth at the Hypostome region to contain the Nematocytes which are the characteristics structures of Phylum Cnidaria or Coelenterata.
