Test 1 - Protists Flashcards
Where is Eukaryotic DNA contained?
The nucleus
How are Eukaryotic cells generally different from prokaryotes? (Physically and internal)
The cells are larger and more complex
Cells that engulfed other cells that already had chloroplasts. What algae is an example of this?
Secondary endosymbiosis
Brown algae
Algae: Single unattached cells
Unicellular algae
Algae: grows in chains of cells
Filamentous algae
Algae: clusters of cells
Colonial or multicellular algae
How does green algae capture and store energy?
Uses chlorophyll to capture, storing in the form of starch
Green algae cell walls contain:
Cellulose like those of plants
Can be unicellular, filamentous or multicellular
Green algae
Filamentous or multicellular, grows in marine waters or intertidal zones
Red Algae
Red Algae used in the production of Nori
Porphyra
Red Algae used in ice cream and cosmetics
Chondrus crispus
Brown algae has different cellular organizations EXCEPT for
Unicellular and colonial
Algae that lives in marine OR freshwater environments and have a hard shell made of silicon dioxide.
Diatoms
Having two flagella
Dinoflagellates
Protozoans are animal like protists that are heterotrophs. They can also be classified as:
Phagotrophs
Osmotrophs
How do Phagotrophs eat?
Feeds by engulfing other organisms
How do Osmotrophs feed?
Absorbs dissolved organic compounds through osmosis
Characteristics of Amoebas
Have wide, rounded pseudopods called lobopods
Phagotrophs
They produce shells made of calcium carbonate. What are their shells called?
- Foraminiferans
Fora - mini - ferans - Tests
Ciliates have many cilia. What are they used for?
To capture food and movement
A unique characteristic of Parabasalids
They have flagella and no mitochondria
Red pigments in red algae are called
Phycobillins
How would you recognize the difference between a male conceptacle and a female conceptacle.
Females have oogonia which are larger than the male antheridia.
In Laminaria, what is the function of the blade?
Photosynthesis
Describe the shape of Amoebas.
Irregularly shaped with pseudopods in different positions
Make a disease caused by Trypanosomes
African sleeping sickness
What kingdom contains pseudomurein
Archaebacteria
What kingdom contained peptidoglycan
Bacteria
