Question

Metazoa is characterised by
A)Unicellular animals
B)Colonial animals
C)Multicellular animals
D)Multicellular decomposers

Answer 1

Hint: Metazoa are contemplated monophyletic, significance that all organisms advanced from a familiar ancestral form. As a faction, they indicate an advancement from multi celled organisms behaving more like provinces with quasi-independent cells, to more highly formulated creatures in which cells conspire to form tightly organized tissues and components.

Complete answer:
Before we discuss the correct option, let us know a little more about Metazoa. Animals can be subdivided into two limbs. The Choanozoa are unicellular marine protists that periodically shape colonies. The rest of the creatures - including birds, fish, amphibians, snakes and mammals - are all multicellular and are collectively pertained to as the Metazoa.

Option C: Metazoa is a faction that encompasses all multicellular animals and physiques distinguished into tissues and organs. They have a digestive compartment lined with specialized cells. They possess cells with a core and a cell coating. They are heterotrophic and employ oxygen for power catabolism. This is the correct option.

Hence, the correct answer is option (C)

Note: Metazoa is a faction of multicellular animals comprising amphibians, fish, snakes, birds, and mammals. However, sponges are not assumed as metazoans. They are a basic shape of metazoans developed from choanozoa that are unicellular marine protists occasionally shaping colonies. Sponges exhibit a single cell-level of the group and do not formulate nerves or muscles as seen in a formal metazoan. Also, metazoans are monophyletic as they are formulated from a single forefather.
