Question

Endosperm formation is suppressed in family

• A. Orchidaceae and Podostemaceae
  
• B. Gramineae
• C. Liliaceae
  
• D. Cyperaceae

Answer 1

The correct option is A Orchidaceae and Podostemaceae


Endosperm suppression

Endosperm formation is suppressed in orchids that belong to the family of Orchidaceae and river weeds of the family Podostemaceae.

These members of the family Podostemaceae produce non-albuminous seeds due to lack of double fertilisation, which is a characteristic unique to this family. The flowers undergo single fertilisation and hence endosperm formation is suppressed in the seeds.

Final answer
c. Orchidaceae and Podostemaceae.
