BIOXII02: SEXUAL REPRODUCTION IN FLOWERING PLANTS

341900 In a fertilized embryo sac, the haploid, diploid and triploid structures are

1 Synergid, zygote and primary endosperm
nucleus
2 Synergid, antipodal and polar nuclei
3 Antipodal, Synergid and primary
endosperm nucleus
4 Synergid, polar nuclei and zygote

341901 Identify the Correct statement

1 Normal type of embryo sac is 8 nucleated
and 7 celled structure
2 Embryo sac contain 7 nuclei formed by
division of megaspore mother cell
3 Megaspore mother cell divides by mitosis
to give rise to 4 haploid megaspores
4 Nucleus of functional megaspores
undergoes 3 meiotic divisions to form 8
nuclei
