Term
what are in the kingdom of protista?
Definition
algae, kelp, slime molds, and paramecia
Term
protista?
Definition
kingdom that includes mostly unicellular, eukaryotic organisms that are not plant, fungi, or animals
Term
history of protist?
Definition
they represent the landmark of evolution on the earth, because they were the first eukaryotic species that were responsible for prokaryotic evolution(plants). They are ancestors to plants, animals, and fungi.
Term
chanoflagellates?
Definition
protist that maybe simlar to forerunners of animals
Term
what features define kingdom Protista?
Definition
nucleus(macro or micro) and other cell membrane-bounded organelles. Macro deals with more day to day functions metabolism and development function. Micro-reproduction
Term
where do protist live?
Definition
free-living: in oceans, lakes, rviers and ponds. Some live off fugi, aniamls, or are parasites to plants and animals ANYTHING WITH MOISTURE
Term
protist ecologically and economically important?
Definition
ecologically:algae produces much of 02 on earth. economically: cause suffering and deaths in animals and plants which cost millions of dollars for research
Term
protist: algae?
Definition
general term that refers to any photosynthetic to protist that live in water. phototsynthetic pigment are yellow, gold, brown, red, and green.
Term
dinoflagellates?
Definition
are characterized by two flagella of different lengths. One propels the cell in a whirling motion. Also have cellulose plates.
Major component of plankton(which is eaten by jellyfish, corals, sea anemones, or giant claims) which provide carbohydrates to their host animals. Some are bioluminesecent, producing flash lights in tropical waters. Some a re parasites
Term
red tide?
Definition
results from a sudden population explosion, or "bloom" of dinoflagellates that turn the water red, orange, or brown. Ususally occurs when nutrients content of the water increses. Toxins from dinoflagellates may become concentrated in the tissuses of clams, scallops, oyster, and mussels. Which can cause a person to get posioning.
Term
motility of protist?
Definition
Many flagella and cillia, locamotion is used to capture food.
Term
osmoregulation contractule vaccule?
Definition
is hypersomic, the water around is hyposomtic, contracle vacolue squeezes water out of the protist.
Term
nutrtion of protist?
Definition
holotrophic-eat the whole thing. corroprate with an organism mutalistic relationship
Term
animal like protist reproduction?
Definition
use conjagation exchange in nucli
Term
varitey in animal-like protist?
Definition
trypanosoma, parabasalid, diplodmand,euglena
Term
euglenoids?
Definition
related to euglena. are unicellular flagellates with elongated cells that primarly inhabit fresh waters. Most have long whiplike flagellum uses in locomtion and short flagellum ghat does not extend from cell.
Term
golden algae?
Definition
photosynthtic quantic protsit with two flagella and carotenoid accessory pigments
Term
diatoms?
Definition
are primarly unicellular algae with two-part silica walls that confer varietY ornate shapes(pennate(glide in grove, are at the bottom sausage like.) centric(base in food chian and circular)Have glass shells which accumulate on the oceans floor, and make sediment on rocks. Also useful in pools fliters, polish, and toothpaste(make things shiny).
Term
red algae?
Definition
similar to green algae in that they store carbohydrates as a modified form of starch, have cell walls containing cellulose, and produce chlorophlly a. Because it can be red or brown it also has phycocyanin and phycoerythin like cyanobacteria. have no flagella or cillia GLIDE. the cell wall contains agar which used to make jelly substances in canned meat or ice cream, also gels in electropharsis
Term
brown algae?
Definition
Most complex and largest protists. Olive green to brown. Reproduce by means of spores, each with two flagella. Seaweed and Kelp are underwater forests. MULTICELLULAR. Algin comes from it's cell walls help thicken substances such as ice cream, candies, dressings. ARE DIATOMS
Term
green algae?
Definition
most plant like of the protist. Use chlorophyll a and b, use starach as a storage carbohydrate, and cell walls contain cellulose. Have alternative generations, with alternating multicellular haploid(gametophyte) and diploid(sporophyte) phases in their life cycle. Live in fresh water and testrial habitats, only 10% live in marrine. many are unicellar, colonial(DEPEND ON EACHOTHER), and multicellular. filamentous(chain like series of cells)XANTHOPHYLL, a&b CAROTENE. 90% IN FRESHWATER, 10% IN MARININE
Term
pink snow?
Definition
green algae, light intensity can destroy cell walls, so they use caryotenes,
Term
water molds?
Definition
no photosynthesis, some produce a filmentous feeding structure similar to those of fungi. Live with fungi, cell walls are chitin, characteristic of walls in fungi. live in damp habitats. Single, amoeboid cells and as large masses that behave as one multicellular organism. PARASITES OF ANIMALS AND PLANTS. POTATO FAMINE. exoenzymes-able to get food AND SAPATROPHIC-LEAVE OFF DEAD THINGS
Term
plsamodial slime mold?
Definition
consist of plasmodium, a mass of thousands of diploid nuclei enclosed by a single cell memebrane. yellow blobs engluf bacteria and other microoganisms. ASEXUAL. in times of drought form stocks of sprongia that produce resistant haploid spores until favorable condition return, and germinate spores and form haploid cells.
Term
protozoa?
Definition
unicellular protists that shares some characteristics of animals, including heterotrophy and usually motility(through cilla and fillia) Some free-living some parasites. most asexual some sexual
Term
amoeboid protozoa?
Definition
produce cytoplasmic extensions know as pseudopodia(false feet), which are important to locomotion and capturing food via exoenzymes(engulfing)
Term
flagellated protozoa?
Definition
live in termites stomach, they also include euglenoids and dinoflagellates, Can cause diseases by living in woman and cause discharge and can cause dirreah
Term
ciliates?
Definition
are common protozoe with complex cells, mostly unicellular, are characterized by abundant hairlike cilia. Propel through water. Cilia also sweep food(bacteria, algae, and other ciliates) into the cell's gullet. A food vacuole then surrounds and transports the captured meal inside cell. In some species, a permanent anal pores releases the wastes. Contractile vacuoles pump excess water out of the cell. Most free living like parmecium.
Term
foraminiferans, or forams?
Definition
ancient marine group of mostly marinen amoeboid protoza with complex, brilliantly colored shells made primarily from calcium carbonante. Live on ocean floor and White Dover Limestone.
Term
responsiveness?
Definition
pH and electricity
Term
examples protist?
Definition
malaria, toxoplasma, hikers dirreha, african sleeping sickness,
Term
reefs?
Definition
2nd in diversity next to rainforest, phyloplankton, eaten by zooplankton, eaten by fish
Term
malaria?
Definition
has vertebrae host and envertebrae host; hides in liver cells, only female mosquito; DDT to get rid of mosquitos
Term
toxoplasma?
Definition
singled celled parasite, dinoflagellets
Term
types of water mold?
Definition
downey mildew of grapes, potatoe faminie
Term
radiolarans?
Definition
make flint diatoms
Term
Unicellular?
Definition
nucleus in center, cellulose walls, starch in chloroplast
Term
