Detailed Solution

The place where sporopollenin is absent is referred to a the germ pore. 

 In angiosperms, the megasporangium (also known as the ovule) usually contains only one meiocyte, which undergoes meiosis to produce four haploid megaspores.

In some plant families such as Rosaceae, Leguminosae, and Solanaceae, pollen grains can remain viable for several months, which means they are capable of fertilizing the ovules over a longer period of time.

The vegetative cell of the pollen grain contains a large, central, and irregular shaped nucleus.

In castor, the endosperm is not completely consumed during embryo development, and it persists in the mature seed.
