by characteristics that resemble those of fungi, plants and animals
How are protists often classified ?
flagella,cilia, or pseudopodia
How do protists move?
binary fission, multiple fission, conjugation
List three ways that protists reproduce :
protist
an organism that is classified as a member of the kingdom Protista
binary fission
a form of asexual reproduction in single celled organisms by which one cell divides into two cells
multiple fission
a form of cell division that produces more than two cells
conjugation
an exchange of genetic material that occurs between two temporarily joined cells
pseudopodium
a retractable, temporary cytoplasmic extension that functions in food injection and movement in certain amoeboid cells
amoeboid movement
a characteristic movement of protozoa that occurs because of the formation of pseudopodium
cilium
a hairlike structure arranged in tightly packed rows that projects from the surface of some cells
pellicle
a protective envelope of nonliving material that covers many protozoans
oral groove
a depressed region in the mouth of some ciliate protozoans, such as parameciums
gullet
an opening into which the mouth pore opens
anal pore
an opening in which wastes are eliminated
contractile vacuole
an organelle that accumulates water and then releases it periodically to maintain somatic pressure
macronucleus
the larger of two types of nuclei found in some protozoans
micronucleus
the smaller, reproductive nucleus found in some protozoans
flagellum
a long, hairlike structure that grows out of a cell and enables a cell to move
pellicle, oral groove, mouth pore, gullet
name the key characteristics of each phylum of animal like protists
algae
autotrophic eukaryotic organisms that convert the sun’s energy into food through photosynthesis but do not have roots, leaves, or stems
gametangium
a cell or organ that produces gametes
phytoplankton
organisms that float near the surface of marine or fresh water and that are the basic source of food in many aquatic ecosystems
diatom
a unicellular alga that has a double shell that contains silica
bioluminescence
the production of light by means of a chemical reaction in an organism
red tide
a population explosion of certain marine dinoflagellates that causes the water to turn red or red brown color and contain poisonous alkaloids
euglenoid
a flagellated unicellular algae
fruiting body
a part of a plant, fungus, or protist that produces seeds or spores
water mold
a funguslike protist that is composed of branching filaments of cells
plasmodial slime molds
a type of protist that has amoeboid cells, flagellated cells, and a plasmodial feeding in its life cycle
cellular slime molds
a type of protist that lives as an individual haploid amoeboid cell that gathers with other such cells in a dense structure called a pseudoplasmodium
algal blooms
a vast increase in the concentration of algae and cyanobacteria in a body of eutrophic water
alginate
a polysaccharide derivative of alginic acid that is found in brown algae and that has many industrial uses including thickening agent in foods and a dental impression agent
agar
a gel like polysaccharide compound used for culturing microbes
diatomaceous earth
a soft, fine, porous deposit that is composed mainly of the skeletons of diatoms
sporozoite
a sporozoan that has been released from the oocyst and is ready to penetrate a new host cell
merozoite
the infective stage of the plasmodial life cycle,infects red blood cells of the host organism
gametocyte
a cell that is not differentiated and that develops into a gamete
produce oxygen,recycle materials, form food webs
