Ukwahlula-hlulwa kwe-cell

Ukwahlulwa-hlulwa kwe-cell kuxa i-cell enye nengunozala wezinye ii-cell yahluke kubini nangaphezulu sithi ezo zii-daughter cells. Ukwahlulwa-hlulwa kwe-Cell kuyinxalenye yokwenzeka kwe-cell cycle. Zimbini iintlobo-ntlobo zokwahlulwa-hlulwa kwe-cell Kwi-eukaryotes: yi-vegetative division, apho intshontsho le-cell ngalinye lifana nqwa nonina i-cell engunozala ke ukutsho. Oku kwahlulahlulwa kwe-cell kwaziwa ngokuba yi-(mitosis), kunye ne-reductive cell division, apho inani lee-chromosomes ezifumaneka kwintshontsho le-cell (daughter cells) liphungulwa ngenani eliyihafu kwelo lazo liphelele, ukuze kwenzeke ii-haploid gametes leyo ke kuthiwa yi-(meiosis). Xa kusenzeka i-Meiosis kuphuma ii-four haploid daughter cells ezine ngokuthi zenze umjikelo omnye we-DNA replication ize ilandelwe kukwahlula-hlulwa okwenzeka kabini:
