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

Answer 1

The correct option is B One meiotic & one mitotic divisions

The grass is a monocot plant. Essential sporogenous cell offers ascend to microspore mother cells or dust mother cells. Each MMC on decrease division offers to ascend to 4 microspores or dust and this arrangement of microspores or dust is called microsporogenesis. Karyokinesis is of progressive sort.
