Chapter 28 Protists Flashcards
Paramecium motility
many cilla
amoeba motility
pseudopod (fingers that can change shape)
Euglena motility
Flagellum
Protist
any eukaryote that is not a plant, animals or fungi
purpose of cytoskeleton
provides structural support for eukaryotic cells
Multicellular protists function
biological functions are carried out by organs
Unicellular protists
carry out the same bioloical function
Photoautotrophs
use sunlight to provide energy to snthesize their food
heterotrophs
can not make their own food instead they ingest other organisms
mixotrophs
capable of both photosynthesis and heterotrophy
endosymbiosis
relationship between two species which one organism live inside the cell or cells
Plastids
double membrane organelle found in cells of plants and algae
plastids gave rise to
red and green algae
secondary endosymbiosis
heterotrophic eukaryotic cell engulfed a photosynthetic eukaryotic cell which survived inside the heterotrophic cell
symbiotic protist
live alongside other species
photosynthetic protists
use energy from the sun to convert CO2 to organic compounds
Parasites of the genus Tryoansoma evade immune responses through
Frequently changing their surface proteins
Locomotion in protists
cilla, flagella, pseudopodia, and undulating membrane
What group is characterized by cells that have more than one nucleus
Ciliates
What group includes photosynthetic unicellular organisms with flagella and contractile vacuoles
Euglenids
What group of protists its though to be closely related to animals
Chanoglagellates
What is important about Diatoms?
Due to the structure of the cell walls they can withstand pressure equal to the pressure under each leg of a table supporting an elephant
green algae is divided into what two groups?
chlorophytes and charophytes
What protists were once categorized as fungi due to their multicellular filaments?
Oomycetes
The holdfast of brown algae functions in
anchoring the algae
What group includes parasitic unicellular organisms specialized in penetrating host cells
Apicomplexans
What group includes species that are toxic to humans?
Dinoflagellates
What is the name of the protist is responsible for the Irish potato famine?
Phytophthora infestans
Which organisms are capable of producing a red tide
Dinoflagellates
