Document Summary

B(cid:272) (cid:271)a(cid:272)teria do(cid:374)"t have (cid:373)ito(cid:272)ho(cid:374)dira, all the fu(cid:374)(cid:272)tio(cid:374)s that are perfkr(cid:373)ed ike respiration, occurs in the cyctoplasimic memberane, function is more complex. Inside are ribosomes, highly organized, like a machine and things working in an efficient manner. Its gonna be exposed to a whole lot of stresses. In their environments, they are subject to many stresses and stressors. Prokaryotes used for bacteria and archea mainly exist as free-living organisms. Osmotic stress changes salt concentration drawn out, The pili, are like sex organs move dna, Any cell has a cytoplasmic membranes, and controls in and out of in and out of. The mitochrondria are the organelle for energy generation in eukaryotics and archea (cid:373)e(cid:373)(cid:271)ra(cid:374)e, there"s a ge(cid:374)o(cid:373)e, viruses do(cid:374)"t have ri(cid:271)oso(cid:373)es, we have a cytoplasm. Conponents: dna genome, ribosomes, cytoplasm, a cytoplasmic memberane, a thick. Going back to structure, theres a chain of 50 layers, they are linked in all kinda ways.
