9B Flashcards
What is a microscopic organism that floats near the oceans surface and is a food source for many marine animals?
Plankton
What causes malaria?
Plasmodium
Give 5 characteristics of an Amoeba
1) protozoan
2) consumer
3) protist
4) eukaryotic
5) moves with pseudopods
Give 5 characteristics of Euglena
1) performs photsynthesis
2) consumer and producer
3) eukaryotic
4) protist
5) has chloroplasts
Give 5 characteristics of a paramecium
1) protozoan
2) consumer
3) eukaryotic
4) protist
5) reproduces by conjugation
Give 5 characteristics of a Spirogyra
1) performs photosynthesis
2) eukaryotic
3) protist
4) has chloroplasts
5) reproduces by conjugation
What two organisms are protozoans?
Amoeba and Paramecium
Which organisms perform photosynthesis?
Euglena and Spirogyra
Which organisms are consumers?
Amoeba, Euglena and Paramecium
Which organisms are Eukaryotic?
Amoeba, euglena, paramecium and Spirogyra
Which organisms are protist?
Amoeba, euglena, paramecium and Spirogyra
Which organisms have chloroplasts?
Euglena and Spirogyra
Which organism moves by pseudopods?
Amoeba
Which organisms reproduce by conjugation?
Paramecium and Spirogyra
What are the two main groups of Protists
Protozoans and Algae
Which group of Protists are are more animal like and give two examples?
Protozoans: paramecium and amoeba
Which group of Protists are plant like and perform photosynthesis? Give two examples
Algae: Spirogyra and Euglena
How does the paramecium obtain its food?
Invagination: paramecium has an oral groove with cilia to tap food. Breaks off to form a food vacuole that digests the food. Undigested food is transported out
How does the amoeba obtain its food?
Pseudopods surround and then digest the food
What are the 3 ways protozoans move?
Flagella: whiplike long hair
Cilia: small hairlike projections: paramecium
Pseudopods: bulge in cytoplasm: Amoeba
Are Protists unicellular or multicellular?
They can be both
What is unicellular?
They can live on their own or in a colony
What is multicellular?
Can’t live on their own. Live in groups and perform a specific task.
How do algae move?
Most are unable to move except Euglena which has flagella
How does the Spirogyra reproduce?
Asexually through mitosis called fragmentation
AND
Sexually by conjugation
How does the Amoeba reproduce?
Asexually through mitosis and cytokinesis
How does the paramecium reproduce?
Asexually
AND
Sexually through conjugation: oral grooves join, nuclear material is shared giving each one a new set of genes and then they separate
