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
Protozoans locomotion uses
Flagella
Causes African sleeping sickness and spread by tsetse fly
Trypanosoma
Protozoans-sporozoans locomotion
Parasitic
Protozoans ; sporozoans reproduce though
Spores
Causes malaria
-Spread by a mosquito
Plasmodium
Drug used to treat malaria
Quinine
Attaches to and spins it’s cilia to create a vortex (water movement)
Vorticella
Malaria matures in the
Liver
Euglena- 2nd group in protist are
Both plant like and animal like
Contain chlorophyll and move by flagella
Euglenoids
Eyespot, chloroplasts, flagellum
Euglena
Plant like protists
Algae
Euglena has
- Eyespot
- chloroplasts
- flagellum
Does have an eyespot but can’t see, does recognize light
Euglena
Photosynthetic
Algae
Multicellular and unicellular
Algae
Algae is classified by pigments which are
- red
- brown
- green +
What are examples of algae
Volvox
Diatoms
Spirogya
Float in water
Diatoms
Photosynthesis but unicellular
Diatoms
Silica shells
Diatoms
What are diatoms commercial value
- insulating materials
- abrasives
- ceramics
- filtering
Insulating materials, abrasives, ceramics, filtering
Diatoms
Move by two flagella
Dinoflagellates
Autotrophs
Dinoflagellates
Green glow and red tides
Dinoflagellates
Most freshwater
Green algae
Food source is plankton
Green algae
Freeliving, colony, filament, volvox top, spirogyra bottom
Green algae
Green algae is (5 things)
Freeliving
colony
filament
volvox top
spirogyra
bottom
A free floating green alga
Desmid
Pediastrium
Green alga
Exists as a thread
Filament
Visible slime mass
Plasmodium
Moves, no cell membrane, many nuclei
Plasmodium
Grow damp organic matter-decompose
Slime molds
Form a stalk, release spores
Slime molds
Reproduces asexually by making spores
Slime molds
