endosperm tissue of angiosperms has what ploidy level
Endosperm About 70% of angiosperm species have endosperm cells that are polyploid.[4] These are typically triploid (containing three sets of chromosomes), but can vary widely from diploid (2n) to 15n.[5]
Seed Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the seed coat from the integuments of the ovule.
Ovule After fertilization, the nucellus may develop into the perisperm that feeds the embryo. In some plants, the diploid tissue of the nucellus can give rise to the embryo within the seed through a mechanism of asexual reproduction called nucellar embryony.
Tissue (biology) In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue.
