It featured at least one centriole and cilium, sex (meiosis and syngamy), peroxisomes, and a dormant cyst with a cell wall of chitin and/or cellulose. In turn, the last eukaryotic common ancestor gave rise to the eukaryotes' crown group, containing the ancestors of animals, fungi, plants, and a diverse range of single-celled organisms.
This passage describes a cell that has at least one centriole and cilium, undergoes sexual reproduction (meiosis and syngamy), contains peroxisomes, and possesses a dormant cyst with a chitin or cellulose cell wall. The last common ancestor of all eukaryotes gave rise to the group of organisms that includes animals, fungi, plants, and many single-celled organisms.
