Answer:

Porifera:-   The

work porifera means organisms having holes. These are non motiles animals

combined to some solid support. There are holes of ‘pores’, on the whole body. These

causes a canal system that helps in circulating water throughout the body to

bring in food and oxygen.

  These animals

are covered with a hard outside layer or skeleton. The body texture involves

quite minimal differentiation and division into tissue. They are generally

known as sponges, and are generally present iin marine habitats. Euplectelea,

sycon and spongilla are some examples of porifera.

 

Coelenterata:- These

are animals found in water. They show large body design differentiation. There is

a cavity within the body. The body is formed of two layers of cells: one forms

cells on the outside of the body, and the other forms the inner lining of the

body.

Some of these species

found in colonies (corals), whereas others have a solitary like – span (hydra).

Jellyfish and sea

anemones are examples of Coelenterata.
