-
what does eukaryotic mean?
the cell contains a nucleus
-
how is fungi different than other plants?
fungi don't make their own food, they get it from other organisms
-
how are fungi cells different than animal cell
fungi cells contain cell walls
-
does fungi include yeast and mold?
yes fungi include some yeast and mold
-
true or false? mold is typically a multi-cellular organism
true
-
how does fungi, mold and yeast reproduce?
by sexual and asexual spores
-
?how does yeast reproduce
asexually by budding
-
true or false? protozoa are single celled eurokyotes?
true
-
true or false protozoa are similar to animal cells in their nutritional needs?
true
-
what are the 3 types of locomotion?
-
define pseudopodia
pseudopodia are extentions that flow in the direction of travel
-
define cilia
cilia are short numerous protrusions that vibrate to propel the protozoa
-
define flagella
flagella are long extensions, few in number and longer than cilia
-
how does protozoa reproduce?
asexually
-
where do protozoa typically live?
in fresh water but can live in animals where they cause disease
-
what are algae?
uni and multicellular photosynthetic organisms
-
how do Algae obtain their nutrients?
by photosynthesis, they make their own food
-
what are some examples of Algae?
seaweed and kelp
-
where can one expect to find Algae?
in freshwater ponds, streams, lakes and oceans
-
what does prokaryotic mean?
organism lacks nuclei
-
what are the bacteria cell wall composed of?
cell wall is composed of a polysaccharide called Peptidoglycan
-
do Archaea have Peptidoglycan walls?
no, instead their wall is composed of other polymers
-
does bacteria and Argae reproduce asexually?
yes
-
are bacteria and argae smaller than eurokyotic cells?
yes, they are smaller than eurokyotic cells
-
true or false?
Archaea are often isolated from extreme environments such as highly saline mono late in california, acidic hot spring and oxygen depleted mud?
true
-
true or false?
Archaea is known to cause disease?
false, they have not been known to cause disease
-
a few bacteria produce disease because they derive their food from the host and produce toxic waste. On the other hand Algae do not cause disease, why not?
because they produce their own food via photosynthesis
