If the diploid number of a flowering plant is 36. What would be the chromosome number in its endosperm
1 36
2 18
3 54
4 72
Explanation:
Endosperm is formed after fusion between a haploid male gamete and diploid secondary nucleus. Thus, endosperm has triploid nucleus; which will have three times the number of chromosomes as in a haploid nucleus. Here, 2n = 36. Therefore, 3n = 54.

In angiosperms, the embryo sac posseses
1 Egg apparatus
2 Synergids
3 Central cell
4 All of these
Explanation:
Each embryo-sac has a three-celled egg apparatus – one egg cell and two synergids, three antipodal cells and two polar nuclei.

Statement A : In angiosperms, male and female gametophytes may not form in one flower. Statement B : Angiosperms are an exceptionally large group of plants occurring in wide range of habitats.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
In angiosperms, male or female gametophyte may or may not form in the same flower depending on whether the flower is bisexual or unisexual.

Eight nucleated female gametophyte is found in
1 Bryophytes
2 Gymnosperms
3 Angiosperms
4 Pteridophytes
Explanation:
Embryo sac is the female gametophyte in the angiosperms. It is 7-celled and 8-nucleate structure.
