eukaryotes

true nucleus and organelles, more complex then prokaryotes
4 kingdoms of eukaryotes
- protist-algea & protozoa
- fungi-
- animal -helminths
unicellular or mulitcelular
- protoza-always uni
- fungi/algea-both
- helminth-multi
eukaryotes cytoplasm

bilayer of phospholipids with protein molecules embedded

contains sterols

selectively permeable
eukaryotic nucleus
- sperated from the cytoplasm by a nuclear envelope
- filled with nucleoplasm
- contains nucleolus
- has chromatin
endoplasmic reticulum
- passageway in the cell
- series of tunnels
- RER
- proteins synthesized on the ribosomes shunted into the cavity of the RER and held for later packaging and transport
ser
Smooth enplasmic reticulum
- detoxification in some cells-liver
- synthesis and storage of nonprotien macromolecules
golgi apparatus
- the packaging machine
- sent from the endoplasmic reticulum to golgi body for modification and packaging before sent to final desitination
contain a stack of cisternaee
mitochondria
- energy generator
- generates the bulk of energy
- contains prokaryotic sized 70S ribosomes
chloroplast

photosynthesis machines

double memebranes

stroma surrounds the thylakoids
ribosome

protien synthesizers

composed of large and small subunits of RNA and protein

larger 80S variety
cytoskeleton
- flexible framework
- anchors organelles
- 2 types microfilament and microtubles
