Q1 · Reproduction in Lower and Higher Plants (Class 12) · EASY
In a typical angiosperm, the embryo sac is 8-nucleate and 7-celled. Which of the following cells contains two nuclei?
Q2 · Reproduction in Lower and Higher Plants (Class 12) · MEDIUM
During microsporogenesis in angiosperms, a diploid microspore mother cell undergoes meiosis to produce four haploid microspores. The arrangement of these microspores is typically:
Q3 · Reproduction in Lower and Higher Plants (Class 12) · MEDIUM
In double fertilization in angiosperms, one male gamete fuses with the egg cell and the other fuses with the two polar nuclei. If the male gametes are haploid (n) and the egg cell is haploid (n), what is the ploidy of the endosperm in a typical angiosperm where polar nuclei are also haploid?
