Develop some hypotheses explaining why only eukaryotic cells have evolved into multi-cellular organisms.

Prokaryotic cells are structurally simple. They are found lone(prenominal) in single-celled and colonial organisms. Eukaryotic cells nurse organelles with their ingest membranes. one-celled eukaryotic organisms are very diverse, provided some(prenominal) colonial and multicellular forms alike(p)ly exist. The get-go of eukaryotic cells plausibly evolved or split off from Archeans, which declare attri simplyes of both prokaryotes ( group O haters, e.g. bacteria), but also contain genes that are more like what youd image in eukaryotes (oxygen lovers e.g. plants and animals). The first eukaryote cells probably lived near oxygen producing stromatolites. Indicators fire that precursors evolved a 2.6 billion years ago--a billion years in the lead the oldest fossil cells. Early single celled eukaryotes probably include amoeba, dinoflagellates, and ciliates (pictured blossom down to the decent). They bulge food by surrounding and riveting it, or through mouth-like op enings, or some other means. Some have internal skeletons cysts.The cysts are found fossilize, but of course you affect a microscope to see them. Eukaryotes are bigger than prokaryotes and were bigger right from the beginning. They needed to be larger to handgrip new move: a nucleus, gene DNA package, and organelles. intent evolved in the sea. It stayed there for the majority of the history of earth. The first fossilized evidence of multi-cellular cells goes anchor to about 1.5 billion years ago.

thither was a scathe to pay for the advantages gained from specialization--death. Prokaryotes cells didnt die--they continued to live by splitting and forming ! both clones. Only environmental hazards like existence eaten or physically destroyed killed them. However, when eukaryotic cells grouped unneurotic and specialized, the cells gave up the might to reproduce by division and began dying. The first replicating molecules were most potential RNA. RNA is a nucleic acid similar to DNA. In testing ground studies it has been shown that some RNA sequences have catalytic capabilities.
