Which of the following is not common in Funaria and Selaginella ?

Options

A. Archegonium
B. Embryo
C. Flagellate sperms
D. Roots

Answer

D

Explanation

(d) Roots are not the common structure in Funaria and Selaginella. Funaria (moss) and Selaginella (pteridophytes) can be related with the presence of archegonium, embryo, flagellated sperms. In Funaria, the plant is attached to the substratum by means of root-like structures called rhizoides, which are multicellular, branched, have oblique cross wall. In Selaginella, special leafless positively geotropic structures called rhizophores arise fromthhe stem at the point of branching. Rhizophore resembles the stem in some characters and roots in other characters and was regardedas organ-sui-genesis (organ of independent origin).
