In angiosperms, the cells of embryo sac are
1 Diploid
2 Haploid
3 May be haploid or diploid
4 Triploid
Explanation:
Generally each ovule has a megaspore mother cell that undergoes meiosis to form four haploid megaspores. Three of them degenerate and one divides to form the embryo sac. Thus,the embryo sac and its cells are haploid too.

In an angiosperm the reproductive parts are
1 Stamen
2 Carpel
3 Both 1 and 2
4 Petals
Explanation:
Unlike the gymnosperms where the ovules are naked, in the angiosperms the seeds are enclosed in fruits.

The diploid sporophyte is dominant in life cycle of
1 Eucalyptus
2 Sunflower
3 Chlamydomonas
4 Both 1 and 2
Explanation:
In the life cycle of angiosperms, the sporophyte is dominant plant body. Eucalyptus and Sunflower are both angiosperms.

Which of the following is incorrect with respect to angiosperms?
1 Megaspore - Haploid
2 Endosperm - triploid
3 Pollen grain - Haploid
4 Egg cell - diploid
Explanation:
Egg cell is haploid. It fuses with the male gamete (n) to form a diploid zygote.
