kingdom prostista Flashcards
what were Protists the first of, and what did they evolve from?
they were the first eukaryotes and evolved from prokaryotes
What did the internal membranes evolve from
folded cell membrane of ancestral prokaryotic cells
Protista are major producers for what ecosystem
aquatic ecosystem
where is seaweed protista used in?
cosmetics, toothpaste, and paints
what are parasitic pathogens?
example
Malaria, beaver fever
what is the Cell structure of Protista
unicellular or multicellular, most do not have cell walls
Eukaryote
explain locomotion for Protista
some demonstrate locomotion
what is the mode of reproduction for protist?
Asexual binary fission or sexual conjugation
what is the mode of nutrition for Protista
heterotrophic and autotrophic
what is the classification method of Protista?
Classified based on nutrition
define Euglenoids
-unicellular,
-1-2 flagella needed for moving
-, they are autotroph
Define ciliates
Unicellular, many Celia, no cell walls, heterotrophs
define apicomplexa
heterotrophs, unicellular, no cell wall, are parasites of animals and cause malaria
what is plasmodium vivax
an infectious disease transmitted through anopheles mosquito bites
where do parasites in Pasmodiim vivax travel and what happens when the rupture?
-travel trough blood stream to liver.
- when they rupture they release parasites that infect red blood cells
define Diatoms
Autotrophs
move by gliding
hard outer glass like shell
Define Amoebas
Heterotrophs
unicellular
move with pseudopods (extension of cytoplasm)
define algae
autotrophs
multicellular
live in colonies
celll walls of cellulose
Are protists producers and consumers
-they’re producers and consumers
explain climate changing affecting protists
warm acidic waters interfere with them making protective shells
Explain the ASEXUAL reproduction in kingdom Protista
One cell forms, two daughter cells by binary fission
explain the SEXUAL reproduction in kingdom Protista
two cells exchange portions of nuclei via conjugation
in protist amoeba what does the gas exchange go through
CELL MEMBRANE
How does gas exchange occur?
by the diffusion of CO2 and O2
