Question

Identify the parts labelled as A and B in the given figure of Equisetum and select the correct option.

• A. (A) - Strobilus, (B) - Rhizome
• B. (A) - Sporophylls, (B) - Tuber
• C. (A) - Sporangia, (B) - Rhizome
• D. (A) - Sporophyte, (B) - Tuber

Answer 1

The correct option is A (A) - Strobilus, (B) - Rhizome

In Equisetum, plant body is differentiated into stem, leaves and roots. Adventitious roots develop in whorls over the nodes of rhizome. Aerial branches develop terminal strobili. In E. arvense, there are two types of aerial branches, green sterile and brown fertile. Terminal strobili occur only on fertile branches.

So the correct option is A.
