| A(n) _____ is a unicellular photosynthetic alga with a unique, glassy, cell wall containing silica. | diatom p585,  |
| _____ are short cellular appendages specialized for locomotion, formed from a core of nine outer doublet microtubules and two inner single microtubules ensheathed in an extension of the plasma membrane. | Cilia p584,  |
| Under the old five kingdom system, the ____ kingdom included all eukaryotic organisms that couldn't be classified as plants, animals, or fungi. Under the new three domain system, advances in molecular biology have made scientists realize that _____ should actually be broken down into several kingdoms with some possibly being placed back into the plant, animal or fungal kingdoms. Therefore, _____ is an informal term used to describe mostly unicellular organisms that are not plants, animals, or fungi. | protist (the answer for all of the blanks) p575 |
| ______ is a type of diplomonad that causes severe diarrhea and is often picked up by drinking untreated water from rivers or lakes contaminated with feces containing the parasite in the dormant cyst stage. | Giardia (This is often the cause of sickness on camping trips when water is not filtered or boiled.) pp578&580 |
What type of protist is pictured below?,  | Diatom (Diatoms, with their glass walls, are a major component of both oceans and lakes. They come in a wide variety of shapes. It's estimated that there are 100,000 living species. When they die, they form sediments called diatomaceous earth, which is used commercially in pool filtration systems. They play a major role in the carbon cycle by removing carbon dioxide through photosynthesis. When they die and sink to the bottom, they tend not to decompose well, so the carbon stays out of the carbon cycle) p585, |
| A type of protozoan that moves by means of cilia is called a(n) _____. | ciliate (The paramecium in the picture below is a classic example of a ciliate. If you look closely, you can make out the small hairlike cilia.) p584,  |
| The protozoan pictured below is a(n) ______., | paramecium p584, |
| Protists that are animal-like in that they capture and consume food are called _______. | protozoans p551 |
| A(n) ______ is a unicellular photosynthetic alga with two flagella situated in perpendicular grooves in cellulose plates covering the cell. | dinoflagellate (The alga that causes red tide is a dinoflagellate. Some dinoflagellates are bioluminscent which means that they can glow in the dark.) p582,  |
The protist pictured below is called a(n) _____.,  | euglena (a common freshwater alga) p581, |
| Photosynthetic protists are commonly called _____ and can be either unicellular or multicellular. | algae p576 |
| Algae and photosynthetic bacteria that drift passively in the pelagic zone of an aquatic environment are called ____. | phytoplankton p582 |
| A short cellular appendage specialized for locomotion, formed from a core of nine outer doublet microtubules and two inner single microtubules ensheathed in an extension of plasma membrane. | cilium (The plural is cilia. The key word here is short. Otherwise it could be a flagellum) p584 |
| A type of protozoan characterized by great flexibility and the presence of pseudopodia is called a(n) _____. | Amoeba p589,  |
| _______ are cellular extensions of amoeboid type cells used in moving and feeding. | Pseudopodia p589,  |
| The most common type of multicellular seaweeds, including kelp, are classified as _____ algae. | brown (The giant kelp in this kelp "forest" are brown aglae.) p586,  |
| The term _____ refers to mostly microscopic organisms that drift passively or swim weakly near the surface of oceans, ponds, and lakes. | plankton (Some larger organisms such as multicellular floating seaweed, most jellyfish, and the Mola Mola fish are classified as plankton also. The fish is classified as plankton because it is not a strong enough swimmer to swim against ocean currents.) p582 |
| The type of protists that are believed to have given rise to true plants are called _______. | green algae p590 |
| Algal blooms of certain types of dinoflagellates cause a phenomenon called ______ in which toxins produced by these algae cause massive fish kills. | red tide p583,  |
| An explosive growth in the population of algae is known as a(n) ________. | algal bloom p583 |
| Red tide is caused by a neurotoxin released by a type of ________., | dinoflagellate p583,  |
| One type of entamoeba is a parasite that causes _______ which causes people to get life-threatening diarrhea from drinking contaminated water. | amebic dysentery (This is the third leading cause of death due to parasites after malaria and schistosomiasis.) p596 |
The _______ shown below is an example of a colonial organism, meaning that it is a colony of individual cells that work together.,  | Volvox p579, |
What is "A" in the picture of this euglena below?,  | flagellum p581,  |
| What is "D" in the picture of this euglena below?, | contractile vacuole (used to get rid of water that is continually entering the cell in the freshwater hypotonic environment) p581, |
| What is "E" in the picture of this euglena below?, | nucleus p581, |
| What is "F" in the picture of this euglena below?, | chloroplast p581, |
What is "A" in the picture of this paramecium below?,  | cilia p584,  |
| What is "B" in the picture of this paramecium below?, | food vacuoles p584, |
| What is "G" in the picture of this paramecium below?, | contractile vacuole (Contracts to squeeze water out of the cell so that it doesn't explode due to being in the freshwater hypotonic environment.) p584, |
