This occurs when two sperm nuclei reach the interior of a female gametophyte, where one sperm will fertilise the egg cell to form a zygote, whereas the other usually fuses with the binucleate central cell, forming a primary endosperm cell, effectively constituting an organism separate from the growing embryo. Approximately 70% of angiosperm species have polyploid endosperm cells which are typically triploid (containing three sets of chromosomes), but can vary widely from diploid(2n) to 15n.
Global air circulation cells move air "clockwise in the Northern hemisphere and counterclockwise in the Southern hemisphere".

Other characteristics used are the cell structure that is whether prokaryote or eukaryote, absence or presence of cell wall, presence or absence of other organelles, cellularity may also be used such as whether unicellular or multicellular, and lastly the mode of nutrition such as whether heterotrophs or autotrophs, e.t.c
