Question

According to the hierarchy of classification, arrange the following terms in proper sequence.
Planate, Cryptogamae, Thallophyta.
A. Cryptogamae - Plantae - Thallophyta
B. Plantae - Thallophyta - Cryptogamae
C. Plantae - Cryptogamae - Thallophyta
D. Thallophyta - Plantae - Cryptogamae

Answer 1

In biological classification, taxonomic rank is basically the level of a group of organisms (a taxon) in a taxonomic hierarchy. The 7 taxonomic ranks, in the ascending order, are :- Kingdom, Phylum/Division, Class, Order, Family, Genus, Species.

Complete Answer:
Plantae - Kingdom Plantae includes all the plants. They are multicellular and eukaryotic.
1. Cryptogamae - Cryptogams are comparatively less evolved. They produce spores, for reproduction.
The divisions that are included under this are - Pteridophyta, Thallophyta, and Bryophyta.
2. Thallophyta - are a group of non-motile organisms, grouped together on the basis of similarities in their characteristics; but they share uncommon ancestors. They were previously categorized as the sub-kingdom of the Plant Kingdom.
According to the hierarchy and the information mentioned above, the sequence of classification is-
kingdom, sub kingdom, division.
So, as per this, because the Kingdom is Plantae; the Sub-kingdom is Cryptogamae; and the Division is Thallophyta; thus, Option c) is the Correct option.

Thus, the correct option is C) Plantae - Cryptogamae - Thallophyta.

Note: Thallophyta are found mostly in wet or moist places; due to the absence of “true roots” and vascular tissue.
1. Plantae - are non-motile, autotrophic, and reproduce asexually by vegetative reproduction.
2. Cryptogamae- hidden reproduction, showing that no seed is produced.
