Question

Describe the process of megasporogenesis.

Answer 1

Dear Student.
Please find below the solution to the asked query.

Megasporogenesis
 
Megasporogenesis   is the process of formation of megaspores in the angiosperms.
The   megaspore mother cell   (MMC) gets converted into megaspores by the process of megasporogenesis.
 
The MMC is large and contains a dense cytoplasm and a prominent nucleus. It undergoes meiosis to produce four  megaspores.
 
In most flowering plants, only one megaspore is functional while the other three degenerate.
 
The single functional megaspore develops into the female gametophyte.  

Hope this information will clear your doubts about the topic.

Answer 2

Megasporogenesis refers to the formation of megaspores in the seeds of the plants. Under this process, nuclear division occurs with the formation of seven-celled eight nucleated embryones. All these nuclei are arranged in such a way that the top three are known as antipodal cell and thereafter the three cells help to form egg (egg + 2 Synergrids) apparatus.
