Question

To form four fully developed polygonum type of embryosac in the angiosperm total number of meiosis and mitosis division required:

• A. $4,12$
• B. $1,3$
• C. $4,4$
• D. $1,12$

Answer 1

Answer: (A)

$4,12$

In angiosperms, for the formation of one embryosac, 1 meiosis takes place in the megaspore mother cell. And subsequently 3 mitotic divisions occur for the development of the 7 celled 8 nucleated structure. So, to form four fully developed polygonum type of embryosac in angiosperm the total number of meiosis and mitosis division generation required are (1*4=4 and 3*4=12) respectively.

So, the correct option is '4,12'.
