Chapter 19 Protist Kingdom Lab Flashcards
What are the 3 main groups of protists?
- Protozoans
- algae
- fungus like
Eukaryotes are
Unicellular
used in certain unicellular protists; used in locomotion and/or in feeding by engulfing food
Pseudopods
No cell wall
Protozoans
Free living or parasite
Protozoans
Consumers
Protozoans
Habitat is aquatic
Protozoans
Protozoans habitat is
Aquatic
What are examples of Protozoans
- Amoeba
- paramecium
- dinoflagellates
Shapeless, aquatic, shape changing
Amoeba
Amoebas get around by this
Pseudopods
Protozoans-Animal like
Grouped by movement
- pseudopods
- cilia
- flagella
- parasites
Microscopic, hair-like projection on the surfaces of some cells and of certain organisms.
Cilia
Long, slender, threadlike, whiplike extension of certain cells or unicellular organisms used mainly for movements
Flagella
How do amoebas eat?
Feeding structures:
- food vacuole
- digestive enzymes
- diffusion
Collect excess water from inside the cell and gets rid of it
Contracting vacuole
Reproduction of amoeba
-asexual reproduction (binary fission)
- inflammation of the large intestine
- diarrhea and vomiting
- caused by an amoeba
Dysentery (an illness)
Fresh water ciliate (uses cilia)
Paramecium
Can go through asexual and sexual
Paramecium
It has 2 nucleus, micronucleus and macronucleus
Paramecium
How do paramecium eat?
Feed on bacteria
How does paramecium eat when the feed on bacteria?
- food enters oral groove
- moves to the food vacuole
- anal pore
Paramecium reproduction through asexual creates
Identical organisms
Paramecium reproduction through conjugation (sexual) does what
- Exchanges genetic information
- Not identical-adds diversity
