Question

why phylum consists of organisms with
cellular level of organisation?​

Answer 1

Answer:

phylum porifera

Explanation:

That is because poriferans are multicellular organisms but there is no distinct relationship between the cells so as to perform any co-ordinated function. In other words, cells in poriferans don’t form any tissues. They are just cellular aggregates where there is no division of labour. Or you can say every cell is upto itself for its life processes. They can’t even be called colonies as colonies have a division of labour.

Answer 2

Phylum porifera they are sponges they have aggregation on cells but don’t perform same functions
