Question

In which one of the family, formation of endosperm doesn't take place?

• A. Orchidaceae
• B. Cactaceae
• C. Ranunculaceae
• D. Malvaceae

Answer 1

The correct option is A Orchidaceae

Orchidaceae is the family of flowering plants which has a very peculiar fragrance. The seeds lack the endosperm and receive the nutrients for development by entering into a symbiotic relationship with mycorrhizal basidiomycetous fungi. No endosperm formation takes place in the members of Orchidaceae, Podostemonaceae and Trapaceae families.

So, the correct answer is option A.
