Is the embryo sac diploid?
As ploidy is a concept of genetics which refers to the number of chromosomes occurring inside the nucleus of a cell. So the ploidy of the embryo sac is haploid.
Is an embryo sac haploid or diploid?
In angiosperms , the embryo sac represents the female gametophyte that derived from the megaspore mother cell through meiosis, that is why it is haploid.
|Question||In an angiosperm the embryo sac is haploid , zygote is diploid and endosperm is triploid. Justify giving reasons for each stage.|
Which of the following structure is diploid?
MMC: The full form is megaspore mother cell, this is diploid cells in the plants, which undergo meiotic division and form four haploid cells called megaspores. So it is the correct answer.
Is the embryo sac haploid?
In angiosperms, each cell of the embryo sac is haploid.
How is embryo sac diploid?
In agamospermy, the embryo sac is diploid because it is formed without meiosis.
Why is an embryo sac diploid sometimes?
Why is an embryo sac diploid in agamospermy ? Embryo sac is diploid because it is formed without meiosis i.e reduction division. The diploid cells divide and form embryo sac giving rise to a diploid sac.
Which is true about embryo sac?
gametophyte of angiosperms (called the embryo sac) is tiny and contains only a few (typically eight) nuclei; the cytoplasm associated more or less directly with these nuclei is not partitioned by cell walls. … …in this group as the embryo sac, develops from the parent spore while it is still retained in the sporangium.
Which of the following structure is not diploid?
Endosperm is a nutritive tissue and it is triploid.
Is ovum is a diploid structure?
Both gamete and egg cell are haploid and result in the formation of diploid zygote.
Which structure is diploid in angiosperms?
The structures that are haploid and diploid in angiosperms
The haploid structures are the male gametophyte and the female gametophyte, while the diploid structure is the zygote, which is formed by the combination of two male and female gametophytes.
