The ploidy of gymnosperms endosperm is n that is haploid that is it is made up of haploid chromosome. The ploidy of angiosperm endosperm is 3n that is triploid .
What is the chromosome number in its primary endosperm nucleus?
Since it is observed that the haploid chromosome number in the case of Saccharum is n = 40 so its primary endosperm nucleus (3n) will also have 120 chromosomes.
Is a seed haploid or diploid?
The embryo is diploid (2n), the endosperm (food reserve) is haploid (n), and the seed coat is diploid (2n).
What is endosperm and its types?
In angiosperms the endosperm is a special tissue which is formed as a result of vegetative fertilization, triple fusion or fusion of a male gamete with diploid secondary nucleus of the central cell. … Depending upon the mode of its formation, angiospermic endosperm is of three types— nuclear, cellular and helobial.
What is the ploidy of ovary?
(a) Ovary- It is the female part of the plant and the female organ of flowers that has ovules. The ovules develop into seeds upon fertilization. It is diploid (2n) in structure.
