|
Sporozoans move by
|
no movement
|
|
Animallike zooflagellates use - to move
|
flagella
|
|
Most zooflagellates reproduce - by - and -
|
asexually by mitosis and cytokinesis
|
|
Some zooflagellates reproduce sexually, such as
|

paramecia
|
|
cilia grouped into rows and bundles and beat in a regular pattern
|
paramecia
|
|
paramecia use - for feeding and movement
|
cilia
|
|
short, hair-like projections that propel a cell
|
cilia
|
|
non motile, parasitic complex life cycles with more than 1 host
|
soprozoans
|
|
attaches, penetrates, and lives as a parasite in a host cell

Trichonympha, dig. systems of termite
|
|
plantlike protists are commonly called..
|
"algae"
|
|
chlorophyll a, b, absorb (different/same) wavelengths of light
|
different
|
|
accessory pigments absorb light at (different/same) wavelengths than chlorophyll, giving algae a (variety/same) colors
|
different, variety
|

cavities in the cytoplasm that are speicalized to collect water
|
contractile vacuoles
|
|
allows paramecia to exchange genetic material with other individuals
|
conjugation
|
|
cytoplasm of cell streams into the pseudopod and the rest of the cell follows
|
amoeboid movement
|
|
animallike protists that use pseudopods for feeding and movement
|
sarcodines
|
|
members of the phylum sarcodina move via temporary cytoplastic projections
|
pseudopods
|
|
very small, bottle-shaped structures used for defense
|
trichocysts
|
|
"working library" of genetic information- a site for keeping multiple copies of most of the genes that hte cell needs in its day to day existence
|
macronucleus
|
|
contains a "reserve copy" of all the cell's genes
|
micronucleus
|
|
an indentation in one side of the organism
|
gullet
|
|
waste materials are emptied into the environment when the food vacuole fuses with a region of the cell membrane called
|
the anal pore
|
|
absorb light at different wavelengths than chlorophyll
