If the diploid (2n) number of chromosomes in an angiospermic plant is 16, what will be the number of chromosomes in its endosperm and antipodal cells?

OR

State the reason why pollen grains lose their viability when the tapetum in the anther is malfunctioning.

If the diploid (2n) number of chromosomes in an angiospermic plant is 16, than the number of chromosomes in it’s endosperm would be 3n which is 3 X8 = 24 and the number of chromosomes in antipodal cells would be 2n which is 2X 8 = 16.

OR

Tapetum present in the anther nourishes the developing pollen grain,if the tapetum is malfunctioning the tapetum would not produce viable male gametes.
