Read the following statements and identify the incorrect statements.
(I) Ovules generally differentiate a single Megaspore Mother Cell (MMC) in the chalazal region of the nucellus.
(II) The MMC undergoes reduction division and produces four megaspores.
(III) In a majority of angiosperms, one of the megaspore gets degenerated while the other three remains functional.
(IV) 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.
(V) The mitotic division are strictly free nuclear, that is nuclear division are immediately followed by cell wall formation.
Choose the correct answer from the options given below.
Text Solution
Verified by ExpertsD
Statements I, III and V are incorrect and these can be corrected as
Ovules generally differentiate a single Megaspore Mother Cell (MMC) in the micropylar region of the nucellus.
In a majority of angiosperms, one of the megaspore remains functional, while the other three degenerate.
The mitotic division are strictly the nuclear, that is nuclear divisions are not immediately followed by cell wall formation.
