Protozoans
They eat ________, _____, and other _________.
bacteria; algae; protozoans
What are unicellular, animal-like organisms and are larger that bacteria?
Protozoans
What can be found in both salt water and freshwater habitats?
Protozoans
Protozoans are divided into four main groups based on the way they move. Theses four groups are the __________, ________, ___________, and __________.
sarcodines; ciliates; flagellates; sporozoans
They are protozoans that move by means of pseudopodia. What is this?
Sarcodines
What are cytoplasmic extensions that are often called “false feet”?
Pseudopodia
What are these protists that have shell-like outer coverings?
Sarcodines
The most common sarcodine is _______. They are found in freshwater habitats and they move by means of pseudopodia.
Amoeba
They also use pseudopodia to get food. They are sensitive to bright light so they thrive in dark places.
Amoeba
What are these protozoans that move by means of cilia?
Ciliates
_____ are small hair-like projections outside the cell _______. They may cover the entire surface of a ciliate or maybe concentrated in certain areas.
Cilia; ciliates
What is the most common and interesting example of a ciliate?
Paramecium
What are protozoans that move by means of their ________ or whip-like structures?
Flagella; Flagellates
________ enable them to move in watery environments.
Flagella
What are some of the diseases the flagellates can cause?
African sleeping sickness
Some flagellates are _________.
Parasites
What is the flagellate that is both an autotroph and a heterotroph?
Euglena
It is a tiny, oval-shaped organism with one pointed end and one rounded end. What is this?
Euglena
The Euglena has an _______, a reddish structure that is sensitive to light. It tends to move towards areas where there is enough light because it uses light energy to make its own food.
Eyespot
What forms spores, which are tiny reproductive cells?
Sporozoans
Most __________ have complicated life cycles.
Sporozoans
What have no means of moving and are carried from place to place by their hosts?
Sporozoans
What can develop into a mature sporozoan?
Spore
What is the most common sporozoan?
Plasmodium
What is the organism that causes malaria?
Plasmodium
Plasmodium is carried by the _________ mosquito.
Anopheles
What happens when a carrier mosquito bites a person?
The mosquito injects its saliva into the bloodstream of the person. The plasmodium travels to the person’s liver, where it forms spores. Spores invade red blood cells, where they grow and multiply, and eventually destroy the cells by bursting to cause the release of more spores into the blood.
_________ ________, also known as _____, are autotrophs, they make their own food.
Plantlike protists; algae
What are capable of photosynthesis like plants?
Algae
_________ ________ lack true stems, roots, or leaves that plants have.
Plantlike protist
Algae are ______________ _________ just like plants.
Photosynthetic Organisms
They form a diverse group of organisms whose sizes range from single-celled, like _________ to many-celled forms like the giant kelps.
Chlorella
What thrives in freshwater, and in marine environment?
Algae
Among the plantlike protists, the ___ _____ and _____ _____ are the closest relatives of land plants.
Red Algae; Green Algae
What are reddish plantlike protists with thousands of known species?
Red Algae
These are commonly known as “seaweeds”. What is this?
Red Algae
What includes the chlorophytes and charophytes?
Green Algae
What mostly live in freshwater habitats and other inhabit marine and terrestrial habitats?
Chlorophytes
The ______-____ ________ include the _____ _____ and the _____ _____.
Fungus-like protists; Slime molds; Water molds
Fungus-like protists have ____ _____ and are capable of forming spores, structures that they use for reproduction.
Cell walls
What vary considerably in size because while some of them measure a a few centimeters, others can be as big as several kilometers?
Slime molds
What is a common slime mold that forms tufts on the outside of rotting logs?
Stemonitis
What is also called as ‘dog vomit mold,” forms yellow crusts on decaying wood?
Fuligo
What molds live in water or in moist environments?
Water molds
Where do fungi and water molds differ?
Cell walls
Water molds have cell walls made of _________, while the cell walls of fungi consists of ______.
Cellulose; Chitin
These are a common problem to farmers because they can be parasitic on farm animals and crops. What is this?
Water molds
What water mold makes the stems and roots of the infected potatoes turn to black slime?
Phytophthora infestans
