trypanosoma cruzi îs a
parasite that leads to chagas disease
tryponosoma cruzi requires
insect host often the triatomine bug also known as the kissing bug
trypanosoma cruzi can cause
heart damage but individuals may remain asymptomatic for years
tryponosama cruzi attacks the heart so ppl will have
severe anemia
what r characteristics of euglenids?
have one or two flagella that emerge from a pocket at one end of the cell
What does euglena have and what does it to?
has plastids and performs photosynthesis in light but moves around in search of food using its flagellum at night
the “sar” clade is a highly diverse group of protists defined by
DNA similarities
SAR stands for
stramenopiles, alveolate, and rhizarians
what do stramenopiles include?
some of the most important photosynthetic organisms on earth
a characteristic of stramenopiles:
most have hairy flagellum paired with a smooth flagellum
stramenopiles ex:
diatoms, golden algae, and brown algae
a characteristic of (stramenopiles) diatoms:
are unicellular algae with a unique 2 part, glass like wall of silicone dioxide
diatoms function:
remove carbon dioxide from the atmosphere thru photosynthesis the carbon dioxide is then converted into oxygen gas which is released into the atmosphere.
stramenopiles- golden algae are named for
their color which results from their yellow and brown carotenoids
the cells of golden algae are typically
bioflagellated, with both flagella near one end
all golden algae are— and some r —-
photosynthetic and some are mixotrophs
(straemnopiles). golden algae MOST r—— but some r —-
unicellular, colonial
(straemonopiles) brown algae are —, all r —-, most r —-
the largest and most complex algae, all are multicellular and most are marine
brown algae ex:
seaweed
brown algae function:
uses chlorophyll to absorb sunlight and convert it into energy in the form of sugars thru photosynthesis and releases oxygen as a byproduct which is essential for the aquatic life
kelps
giant seaweed and live in deep parts of the ocean
brown algal seaweeds have plant like structure:
holdfast,stipe,blade
holdfast
rootlike, which anchors the alga
stipe
stemlike, which supports the leaf like blades
