|
Are eukaryotes animals? Why or why not?
|
No, they are animal-like because they lack a cell wall (like plants), have at least one motile stage in the life cycle, and most ingest their food.
Almost all modern day eukaryotes have mitochondria and are aerobic (use oxygen) |
|
|
What do protists live?
|
Anywhere there is moisture!
Marine, freshwater, soil, inside animals, etc |
|
|
How do protists feed?
|
Heterotrophic- phagocytosis (engulf visible particles), pinocytosis (take in fluid droplets by a process of channel formation)
|
|
|
How can protists reproduce?
|
Asexual: binary fission (dividing into two identical organisms), multiple fission (more than two created all at once), budding (a little guy grows up into an identical organism)
Sexual: conjugation followed by fission |
|

Habitat: Feeding: Locomotory structures: Reproduction: |
Identify: Phylum Euglenozoa (Euglena)
Habitat: freshwater Feeding: photosynthesis Locomotory structures: flagella Reproduction: binary fission |
|
|
Identify: Phylum Apicomplexa (Gregarina)
Habitat: Feeding: Locomotory structures: Reproduction: |
Identify: Phylum Apicomplexa (Gregarina)
Habitat: parasites of many animals Feeding: absorb nutrients Locomotory structures: none! Reproduction: complex life cycle inlcudes several hosts, asexual and sexual reproduction |
|
|

Habitat: Feeding: Locomotory structures: Reproduction: |
Identify: Phylum Euglenozoa, Subphylum Kinestoplasta (Trypanosoma)
Habitat: Human host Feeding: absorbs nutrients Locomotory structures: fagella and undulating membrane ***responsible for african sleeping sickness, spread by tsetse fly! |
|
|
Identify: Apicomplexa (Plasmodium)
Habitat: Feeding: Locomotory structures: Reproduction: |
Identify: Apicomplexa (Plasmodium)
Habitat: humans and mosquitos Feeding: absorption Locomotory structures: none! Reproduction: two stages: sexual in mosquito and asexual in human host |
|
|
Identify: Ciliophora (Paramecium)
Habitat: Feeding: Locomotory structures: Reproduction: |
Identify: Ciliophora (Paramecium)
Habitat: freshwater Feeding: phagocytosis Locomotory structures: cilia Reproduction: conjugation then fission |
|
|
Identify: Phylum Ameba (Amoeba)
Habitat: Feeding: Locomotory structures: Reproduction: |
Identify: Phylum Ameba (Amoeba)
Habitat: Everywhere Feeding: Phagocytosis Locomotory structures: pseudopodia Reproduction: binary fission |
|
|
What is osmoregulation and how do you identify it?
|
rids an ameoba of excess water
the contractile vacuole (a clear bubble w/o particles) swells with fluid and then pops and disappears. |
|
|
What are foraminiferans?
|
marine amebas that secrete a skeleton of one or more chambers with long delicate pseudopodia that extend through the pores
|
|
|
What are heliozoans?
|
actinopod amebas...look like a sunburst
|
|
|
What are radiolarins?
|
marine actinopod amebas...w/ a transparent skeleton of silica
|
|
|
What is a pellicle? what type of protist has it?
|
protective but flexible body covering found on a euglena
|
