Is Synergids is diploid?

Is Synergids haploid or diploid?

Synergids are the two nuclei in the embryo sac of flowering plants that are closely associated with the oosphere or egg cells, to form the egg apparatus. They are haploid.

What is the ploidy of synergid?

Answer: Embryo developed from the synergid ishaploid as the ploidy of the synergid is haploid. Embryo developed from the nucellus is diploid as the ploidy of the nucellus is diploid.

Is antipodal cell diploid?

haploid (iii) Antipodal? … diploid Since, all these cells three cells (synergid, polar nuclei and antipodals are) formed by mitosis from the functional megaspore, they are haploid (n). Egg cell fertilizes with the male gamete to form a diploid zygote.

What are Synergids cells?

Synergid cells are two specialized cells that lie adjacent to the egg cell in the female gametophyte of angiosperms and play an essential role in pollen tube guidance and function. … The synergids are also essential for the cessation of pollen tube growth and release of the sperm cells.

What is meant by Synergid?

: one of two small cells lying near the micropyle of the embryo sac of an angiosperm.

Is pollen grain haploid or diploid?

Pollen grains mainly represent the male part of the reproductive process in plants and trees. After the formation of the four haploid microspores occurs it fuses to form pollen grain and the development of the pollen grain walls starts. Hence pollen grain is a haploid structure.

What is the ploidy of antipodal cell?

DNA content in differentiated antipodal cells has been determined by a cytophotometric analysis; in the case of a mature embryo sac, the ploidy of antipodal cells varied from 8 to 32C.
