Acellular slime mold mold that forms into a plasmodium
Algae often unicellular--can grow in large groups--kelps and seaweeds--major part of phytoplankton--most are motile due to flagella--cell walls composed of cellulose
Amoebas protazoans--pseudopodia--move by crawling--
ATP (adenosine triphosphate)--the cells energy storage chemical
Cellular slime mold mold which grows as a group of individual cells
Chlorophyll found in algea--uses energy from the sun to convert carbod dioxide and water into carbohydrates and oxygen--captures photons of light and transfers energy to mitochondria that produce ATP
Chloroplasts organelles that contain chlorophyll--
Ciliates protazoans with cilia--cilia beat coordinately--cilia near the oral cvity propel food to the oral opening
Cyst protazoans that are resting/dormant--more resistant to drying, low temps, or scarcity of food--reminiscent of bacterial endospores--not heat stable & do not survive for weeks/months
Diatoms algae that produce a silicon structural matrix that settles to the bottom of the ocean when the organisms die--skeletons are tiny porous rocks
Flagellates (flagella)--motility appendages of protozoans--use their organelles of motility for locomotion and food gathering--
Photosynthesis when energy from sunlight is used to convert carbon dioxide and water into carbohydrates
Phytoplankton (phyto--plant--plankton--drifting)--algae are a major part of this--free-floating masses found in the worl's saline waters--produce more oxygen than all Earth's forests--form the basis for marine food chain
Plasmodium a collection of cells that are fused together--each one grows larger as the nuclei divide
Protists include a broad grouping of eukaryotes other than plants, animals, and fungi--includes algae, protozoa, and slime molds--all protist cells exhibit same functions--rigid cell walls made of polysaccharides or rock salts--
Protozoans unicellular protists that lack photosynthetic ability--identified microscopically by locomotion apparatus, general shape/size, # of nuclei, & presence of cyst forms--most in water--abundant in soil and in/on animals and plants
Slime mold not considered fungi--produce spors and grow in fungi habitats--several have flagella/pseudopodia--fungi are nonmotile--reclassified as protists--molds form fruiting bodies/collections of cell material that rise above area of growth & form spores
Sporozoites protozoans with no motility appendages--do not make spores--produce and infectious form called sporozoites--
Trophozoite vegetative/growing form of protozoan--
