Solution
The correct option is A True In seed plants, the ovule ("small egg") is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: The integument(s) form its outer layer(s), the nucellus (or remnant of the megasporangium), and female gametophyte (formed from haploid megaspore) in its centre. Matureovulesi.e. megasporangia in angiosperms are mainly of fivetypes. The principle of classification is based on thepositionof the micropyle, chalaza and hilum with regard to one another and also to the placenta.
