Question

Process of formation of megaspores from the megaspore mother cell is termed as _________.
1. Sporulation
2. Microsporogenesis
3. Megasporogenesis
4. Apomixis

Answer 1

Correct Answer - Option 3 : Megasporogenesis

The correct answer is Megasporogenesis.

• The process of formation of megaspores from the megaspore mother cell is called megasporogenesis.

• In flowering plants, the megaspore is produced inside the nucellus of the ovule.
• During megasporogenesis, the megasporocyte or megaspore mother cell undergoes meiosis to produce initially four haploid cells i.e. the megaspores.
• After megasporogenesis, the megaspore develops into the female gametophyte i.e. the embryo sac in a process termed megagametogenesis.
