Unicellular eukaryotes chapter 11 Flashcards
What are micro tubules
internal structure to cilia and flagella
what are intermediate filaments
limit cell stretching and support the plasma membrane
What are microfilaments
form the cell cortex and are very important in cell movement and shape change
What are chemoautotrophs
Autotrophs that get their energy by inert chemical compounds
What are photoautotrophs
autotrophs that get their energy by photosynthesis
How is phagocytosis defined
Lysomes
How is trogocytosis defined
Entamoeba bites off pieces of host cells
How is Saprozoic defined
pinocytosis of dissolved nutrients (straw)
What is osmoregulation
The maintenance of constant osmotic pressure in the fluids of an organism by the control of water and salt concentration
What is encystment
Cyst form inside
What is excystment
cyst form outside
How is the Clade Metamonada defined
Basal bodies and flagella generally groups of 4, many parasitic or endosymbionts, multiple phyla within this
How is the phylum euglenozoa defined
Nucleoli remains present during cell division
EX: Euglena - free living, Trypanosoma – parasite, african sleeping sickness
How is the clade of Alveolata defined
Presence of Alveoli (membrane bound sacs) beaneth cell membrane
EX: Dinoflagellata, Ciliophora, apicomplexa
How is the phylum ciliophora defined
Covered in cilia at some point in life cycle
generally larger than others
most free living
EX: Paramecium, stentor
How is Phylum Dinoflagellata defined
Commonly have two flagella
about half of them are photoautotrophic
many are bio-luminescent
Body naked or covered by cellulose lates or valves
How is phylum apicomplexa defined
All endoparasites
have an apical complex
How is phylum foraminifera defined
Shelled amoebas with slender pseudopodia
Most test are many chambered and made of calcium carbonate or aggregates
How is the phylum radiolarians defined
Shelled amoebas with test of silicon or strontium
In the water column, and mostly live in shallow water
How is the phylum amoebozoa defined
Both naked and shelled amoebas, some flagellated
Includes: Slime molds, amoeba proteus, Entamoeba histolytica
How is the phylum Opisthokonta defined
Usually 1 posterior flagella
paraphyletic since animal and fungus own kingdoms
choanoflagellates: solitary or colonial cell that are most likely sister taxon to animals
