  • Read the following statements and find out the incorrect statements. a. Ovules generally differentiate a single megaspore mother cell (MMC) in the chalazal region of the nucellus. b. The MMC undergoes reduction division and produces four megaspores. c. In a majority of angiosperms, one of the megaspore is degenerated while the other three remains functional. d. The nucleus of the functional megaspore divides mitotically three times and form 2-nucleate, 4-nucleate and later 8-nucleate stages of the embryo sac. e. These mitotic division are strictly free nuclear, that is, nuclear division are immediately followed by cell wall formation.

    The microspores, as they are formed, are arranged in a cluster of four cells- the microspore tetrad. As the anthers mature and dehydrate, the microspores dissociate from each other and develop into

    Assertion: During embryogenesis, cell division increase the number of cells in the developing embryo. Reason: During embryogenesis, cell differentiation helps groups of cells to undergo certain modification to form specialised tissues and organs to form an organism.
