polyphyletic, monophyletic
|
|
|

|
two of the earliest lineages of protists. contain parasitic members that can infect humans
|
|
|
euglenoids
|
can be photosynthetic, have an eyespot that helps guide them
|
|
|
trypanosomes
|
flagellated protozoans
two species that cause african sleeping sickness and chagas disease |
|

T. vaginalis
|
STD that can cause damage to reproductive system
|
|
|
Giardiasis
|
caused by Giargia lamblia, causes intestinal problems by drinking contaminated water
|
|

formaniferans
|
hard exterior, calcareous material, peppered with tiny holes through which they catch food, primary component of ocean sedimants
|
|
|
paramecium
|
ciliate that lives in aquatic environments, relies on contractile vacuoles to make sure that it doesn't drown. transmited through contaminated water
|
|
|
plasmodium
|
an infamous apicomplexan that causes malaria=. it is transferred through a specific type of mosquito that draws blood from individual, gametes then from zygotes and develop into infectious stages.
|
|
|
euglena gracilis
|
photosynthetic, flagellated
|
|
|
trypanosoma brucei
|
flagellated, african sleeping sickness, biting insects infected
|
|
|
dinoflagellates
|
red tide, flagellated, gonyaulax
|
|
|
chrysophytes
|
include yellow-green algae, golden algae and diatoms.
|
|
|
xanthophylls and fuxanthins
|
except in yellow-green algae, these block the green color of the chorlophyll in algae and diatoms.
|
|
|
diatoms
|
have external overlapping shells of silica
|
|
|
brown algae
|
include giant kelp that serve as platforms for ecosystems. commercial source of ALGINS, which are thickening agents
|
|
|
Oomycotes
|
ancient nonphotosynthetic stramenophiles. most are water molds but some are downy mildew which were responsible for the irish potato famine
|
|
|
red algae
|
very similar to cyanobacteria. AGAR is extracted from cell walls to be used as gelling agent.
|
|
|
green algae
|
more complex-store carbs as starch, some photosynthesis and have cellulose in walls but are aquatic
|
|
|
amoebas vs. slime molds
|
both can be predatory that move with pseudopods and have mitosis and cytoplasmic division. slime molds can form a multinuclear plasmodium, or can be multicellular masses
