Document Summary
According to morphology (aka form science): species fall into two broad categories: prokaryotes, eukaryotes. Organisms fall into 3 broad domains: bacteria- prokaryote, archaea- prokaryote, eukarya- eukaryote. Bacterial cells were thought to be very simple but are actually very highly organized prokaryotic cells. Plasma membrane chromosomes ribosomes cell walls some prokaryotes have flagella inner membranes (where photosynthesis occurs) Plasmids- circular dna found in prokaryotes/bacteria that also consists of proteins. Dna part of the plasmid provides genetic information. Protein part of the plasmid provides structural support for the dna. Supercoiling- when dna in prokaryotes coils on itself with the help of enzymes. Nucleoid- a region of the cell in prokaryotes that contains its genetic information. Represe(cid:374)ts (cid:1006)(cid:1004)% of the (cid:272)ell"s total (cid:448)olu(cid:373)e. Organelles- membrane bound compartments inside the cell that contain enzymes or structures that are specialized in a specific function. Bacterial organelles perform the main tasks: storing calcium ions, holding magnetite.
