(yoo-karr-ee-oht or yoo-karr-ee-ət)
.
(a eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within ‘membranes’)
(‘eukaryotes’ belong to the taxon eukarya or eukaryota)
(the defining feature that sets ‘eukaryotic cells’ apart from ‘prokaryotic cells’ (‘bacteria’ + ‘archaea’) is that they have membrane-bound organelles, especially the nucleus, which contains the genetic material and is enclosed by the nuclear envelope)
(the presence of a nucleus gives eukaryotes their name, which comes from the greek εὖ (eu, “well” or “true”) and κάρυον (karyon, “nut” or “kernel”))
(‘eukaryotic cells’ also contain other ‘membrane-bound organelles’ such as ‘mitochondria’ and the ‘golgi apparatus’)
(in addition, ‘plants’ + ‘algae’ contain ‘chloroplasts’)
(‘eukaryotic organisms’ may be ‘unicellular’ or ‘multicellular’)
(only ‘eukaryotes’ form ‘multicellular organisms’ consisting of many kinds of ’tissue’ made up of different ‘cell types’)
(‘eukaryotes’ can reproduce both asexually through ‘mitosis’ and sexually through ‘meiosis’ + ‘gamete fusion’)
(in ‘mitosis’, 1 cell divides to produce 2 ‘genetically identical cells’)
(in ‘meiosis’, ‘DNA replication’ is followed by 2 rounds of ‘cell division’ to produce 4 ‘daughter cells’ each with half the # of ‘chromosomes’ as the ‘original parent cell’ (or ‘haploid cells’))
(these act as ‘sex cells’ (‘gametes’ – each ‘gamete’ has just 1 ‘complement’ of ‘chromosomes’, each a unique mix of the corresponding pair of ‘parental chromosomes’) resulting from ‘genetic recombination’ during ‘meiosis’)
(the domain ‘eukaryota’ appears to be ‘monophyletic’, and so makes up one of the 3 domains of life)
(the 2 other domains (‘bacteria’ + ‘archaea’), are ‘prokaryotes’ and have none of the above features)
(‘eukaryotes’ represent a tiny minority of all living things)
(however, due to their much larger size, eukaryotes’ collective worldwide biomass is estimated at about equal to that of ‘prokaryotes’)
(‘eukaryotes’ first developed approximately 1.6 – 2.1 billion years ago (during the ‘proterozoic eon’))
