Question

Which of these processes are necessary for the complete development of male gametophyte from pollen mother cell?

• A. One meiotic and two mitotic divisions
• B. One meiotic cell division and one mitotic cell division
• C. Two meiotic cell division and one mitotic cell division
• D. Two mitotic cell divisions

Answer 1

Answer: (A)

One meiotic and two mitotic divisions

One meiotic and two mitotic divisions will result in complete development of male gametophyte from pollen mother cell. Each pollen mother cell on meiosis gives rise to 4 microspores or pollens which is the beginning of male gametophytic generation.
