monomers and polymers
what do lipids have
Carbon hydrogen oxygen
saturated unsaturated
saturated

cell theory¿
all living things are made from cells
cells arise from other cells
cells provide the basic structure for all living things
eukaryotic¿
cells contain nucleus and membrane bound organelles (multicellular or unicellular)
prokaryotic¿
cells do not contain a nucleus or membrane bound organelles (unicellular organisms)… bacteria
autotrophic¿
makes their own food
heterotrophic¿
organism must consume (eat) its food
is bacteria prokaryotic or eukaryotic
prokaryotic
domain of bacteria?
archaea or bacteria
kingdom of bacteria?
archaebacteria or eubacteria
3 basic shapes of bacteria
cocci- round
bacilli- rod
spirilla- spiral
reproduction of bacteria?
binary fission (asexual)
function of bacteria
- decomposers (helps to return nutrients to the soil)
- human body (digests food, fight off bad bacteria, make vitamins)
- food (cheese,yogurt,sourdough bread…etc,)
are protists eukaryotic or prokaryotic
eukaryotic
how does amoeba move?
moves by stretching out its cytoplasm (pseudopodia)
is amoeba autotrophic or heterotrophic?
heterotrophic
what domain and kingdom does amoeba belong to
domain- eukarya
kingdom- protista
how does euglena move
moves with a whip-like tail (flagella)
is euglena autotrophic or heterotrophic?
