Question

Incipient heterospory is linked with organism bearing one of the following.

• A. Glumes
• B. Ligule
• C. Scutellum
• D. Coleoptile

Answer 1

The correct option is B Ligule

Heterospory is the production of spores of two different size and sex. When the spores of different sizes are found in the same sporangium but the size of spore do not correspond to the sex is known as incipient heterospory. Each leaf of Selaginella bears on its upper surface near its base a small membranous, tongue like outgrowth called ligule. The presence of ligule and incipient heterospory is used to group certain taxa in certain phylogeny.

So, the correct answer is option B.
