Question

multi cellular animals without tissue are include in the sub kingdom​

Answer 1

Explanation:

Kingdom Animalia consists of organisms that range from the simplest of the animal forms to the most complex.

Currently 1.7 million living organisms are known to science. Out of these 1.2 million are animals and about 0.5 millions.

Hence the correct answer is option D.

Answer 2

Answer:

The subkingdom Parazoa includes multicellular organisms having less-specialized cells than in the Metazoa. It includes the phylum Porifera (sponges) and the organisms under this phylum lack tissues with a mass of cell embedded in a gelatinous matrix. Jellyfishes belong to the phylum Cnidaria and they do not belong to this subkingdom.

So, the correct option is 'animals lacking tissues and organs'.
