Question

Match items in column $I$ with those in column $II$.
Select the correct answer from the following.

(a) Floridean starch	(i) Metasequoia
(b) Rhizophore	(ii) Cycas
(c) Living fossil	(iii) Selaginella
(d) Coralloid root	(iv) Rhodophyceae

• A. a(ii),b(iii),c(i),d(iv)
• B. a(iv),b)(i),c(iii),d(ii)
• C. a(iv),b(iii),c(i),d(ii)
• D. a(i),b(ii),c(iii),d(iv)

Answer 1

The correct option is C a(iv),b(iii),c(i),d(ii)

Rhizophores arise from angle meristems located at shoot branch points in many species of Selaginella. The living fossil in reference is the Dawn Redwood, Metasequoia glyptostroboides. The coralloid roots contain symbiotic cyanobacteria (blue-green algae), which fix nitrogen. Floridean starch is a type of storage glucan found in glaucophytes and in red algae (also known as rhodophytes), in which it is usually the primary sink for fixed carbon from photosynthesis. So the correct option is ' a(iv),b(iii),c(i),d(ii)'.
