Question

How are the criteria for deciding divisions in plants different from the criteria for deciding the subgroups among animals?

Solution

Criteria for deciding divisions in plants are:-

(i) Differentiated/ Undifferentiated plant body

(ii) Presence/ absence of vascular tissues

(iii) With/without seeds

(iv) Naked seeds/ seeds inside fruits

Criteria for deciding subgroups among animals are:-

Kingdom Animalia is divided into two major groups on the basis of the presence or absence of a notochord.

Non-chordates do not possess a notochord, while all members of the phylum chordates possess a notochord.

Non-chordate is further divided into subgroups on the basis of the following features:-

On the basis of the above features, non-chordates are divided into the following subgroups: Porifera, Coelenterate, Platyhelminthes, Nematodes, Annelids, Molluscs, Arthropoda, and Echinodermata.

All members of the phylum chordate possess a notochord. However, some animals such as Balanoglossus, Amphioxus, Herdmania, etc. have a notochord, which is either absent or does not run the entire length of the animal’s body. Therefore, these animals are kept in a separate sub-phylum called Protochordata, and the rest of the chordates are included in the sub-phylum vertebrata. The members of the sub-phylum vertebrata are advanced chordates. They are divided into five classes: Pisces, Amphibian, Reptilia, Aves, and Mammalia.
