Question

To form four fully developed polygonum type of embryosacs in angiosperms, total number of meiosis and mitosis divisions generations required are respectively

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

Answer 1

The correct option is 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 1x4=4 and 3x4=12 respectively.
