MD 3 Protista

Information from Module 3: Kingdom Protista

QuestionAnswer
Pseudopod "False Feet" a temporary, foot-like extension of a cell, used for locomotion or engulfing food
Nucleus Region of a eukaryotic cell that contains the cell's main DNA
Vacuole Membrane-bounded "sac" within a cell
Ectoplasm Thin, watery cytoplasm near the plasma membrane of some cells
Endoplasm Dense cytoplasm near the interior of some cells
Pellicle Firm, flexible coating outside the plasma membrane
Flagellates Protozoan that propel themselves with a flagellum
Chloroplast Organelle containing chlorophyl for photosynthesis
Chlorophyll Pigment necessary for photosynthesis
Eyespot Light-sensitive region in certain protozoa
Symbiosis Close relationship between 2+ species where at least one benefits
Mutualism Relationship between 2+ organisms of different species where all benefit
Commensalism Relationship between 2 organisms of different species where one benefits and the other is neutral
Parasitism Relationship between 2 organisms of different species where one benefits and the other is harmed
Cilia Hairlike projections extending from the plasma membrane and are used for locomotion
Macronucleus controls metabolism
Micronucleus controls reproduction
Plankton tiny organisms that float on water
Zooplankton tiny floating organisms that are eigher small animals or protozoa
Phytoplankton
Thallus Body of a plant-like organism not divided into leaves, roots, or stems
Algal Bloom When algae take over their habitat and water appears the same color as algae
Carotenoids Yellowish pigment
Cellulose Substance (of sugar) common in cellwalls of main organisms
Filaments Colonies of chainlike threads
Diatomaceous earth Cell wall remains of dead diatoms clumped together
Holdfasts Special structure used by an organism to anchor itself
Sessile colony Colony that uses holdfasts to anchor itself to an object
Red Tide dinoflagellate bloom in Nutrient-rich water
Describe Phylum Sarcodina No standard body shape, uses pseudopods to engulf prey, forms cysts to survive life-threatening conditions, Entaemoeba hystolytica causes dysentery
Describe Genus Euglena Phylum Mastigophora, Flagellates, many habitats, autotrophic+saprophytic, pellicle, photosynthetic (Chloroplast and Clorophyll), eyespot, reproduce asexually
Describe Genus Volvox Phylum Mastigophora, photosynthetic, colonial, 2 flagella, sexual reproduction
Describe Genus Trypanosoma Phylum Mastigophora, carried by tsetse fly and infect humans with African sleeping sicknes, or help termites digest cellulose
Describe Genus Paramecium Phylum Ciliophora, macronucleus, micronucleus, oral groove, gullet (becomes food vacuole), oral pore, anal pore, asexual reproduction as well as special congugation
Describe Genus Stentor Phylum Ciliophora, trumpet-shaped, creat micro-current to sweep food into gullet
Most Ciliates are... ...not pathogenic, except for Balantidium Coli, which causes dysentery and is animal parasite
Describe Phylum Sporoza All 30,000 species are parasitic, form spores
Describe Genus Plasmodium Causes malaria through mosquitoes, alternation of generations
Alternation of Generation sometimes engage in reproduction that forms sporesad sometimes in reproduction that does not (Plasmodium)
Describe Phylum Chlorophyta "Green Algae", cell walls of celllulose
Describe Genus Chlorella Phylum Chlorophyta, individuals, photosynthesis, have mutalistic symbiosis
Describe Genus Desmid Phylum Chlorophyta, simple colonies/individual, usually mirror images
Describe Genus Spirogyra Phylum Chlorophyta, spiral chloroplasts, colonies of filaments
Describe Phylum Chrysophyta Greatest producers of oxygen, called diatoms, cell walls of silicon dioxide, convert food into oil,
Describe Genus Dynobyron Phylum Chrysophyta, alge that form colonies with holdfasts (sessile colony)
Describe Phylum Pyrrophyta Dinoflagellates (two flagella), marine waters, walls of cellulose, Gymnodinium brevis cause red tides
Describe Phylum Phaeophyta Multicellular (exception to Protista), "brown algae", alginic acid or algin
Describe Genus Macrosystis Phylum Phaeophyta, kelp
Describe Genus Fucus Phylum Phaeophyta, rockweed, air bladders
Describe Phylum Rhodophyta Red algae, multicellular, Genus Corallina and Hildenbrandia
Things about ALL Protista Composed of eukaryotic cells and designed by God
Characteristics of Protozoa Individuals, heterotrophic, have locomotion
Characteristics of Algae Colonies, autotrophic, just float (no locomotion)
Examples of Phylum Mastigophora Genus Euglena, Volvox
Examples of Phylum Ciliophora Genus Paramecium, Stentor

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
