Microspore mother cell forms

Megasporogenesis is defined as the process of formation of megaspores from the megaspore mother cell (MMC). MMC is a diploid cell This process occurs inside the nucellus of the developing ovule. Ovules generally differentiate a Megaspore mother cell/s in the micropylar region of the nucellus.

Read the following statements and find out the incorrect statements. a. Ovules generally differentiate 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 follwed by cell wall formation.

In the developing ovule of most of the Angiosperms , megaspore mother cell is situated within the nucellus

Assertion : The megaspore mother cell divides mitotically to produce four spores Reason : Megaspore mother cells are diploid and megaspore is haploid.
