Biology

nucleus, most are multicellular, larger than prokaryotic cells, Eukarya cells

Bacteria, Archaea, Eukarya

plasma membrane, single chromosome, ribosomes (synthesize proteins), stiff cell wall

one supercoiled circular chromosome, plasmids (small supercoiled, circular DNA molecules)

all contain ribosomes, internal photosynthetic membranes, membrane closed organelles, cytoskeleton

membrane bound internal compartments

flagella, most have a cell wall (bacteria and archaea cell walls are a rough, fibrous layer that surrounds the plasma membrane)

large and highly organized, surrounded by a double bounded membrane nuclear envelope, information storage and processing

membrane bound tubes and sacs studded with ribosomes, interior is called the lumen, new proteins- folded and processed in lumen

no ribosomes, synthesizes enzymes, phospholipids, fatty acids

series of stacked flat membranous sacs-cisternae, processes- sorts- ships proteins synthesized in RER, vesicles carry materials to and from

non-membranous, subunits containing RNA molecules and proteins, attached to the RER or free in cytosol, protein synthesis

globular organelles bound by a single membrane, center of oxidation

single membrane bound structures- 40 different digestive enzymes, in animal cells,digestion and waste processing

large membrane bound structure, used for storage of water and/or ions

Two membranes; inner- cistae, inside inner- mitochondria matrix, have own DNA, ATP production

plant and algal cells, photosynthesis, outside vesicles is the stroma, vesicles called thylakoids-grana

Fungi (chitin), algae and plants (cellulose) have a stiff outer cell wall,

consists of the SER+RER+golgi apparatus, protein+lipid synthesis

Actin filaments, Intermediate filaments, microtubules
