-
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
