T or F All organisms need a carbon and a energy source
True
100
The purple/green photosynthetic bacteria, light energy, organic carbon source
PhotoHeterotrophs
100
Movement of water from high to low concentration across a semipermeable membrane
Osmosis
100
Molecules move form HIGH to LOW concentration "down a concentration gradient" ; No ATP energy is spent
Passive Transport
100
Ingestion of solid particles or whole cells; cell membrane extends & engulfs the particle, enters cell in a vacuole.
Phagocytosis
200
Heterotrophs- organic carbon source (usu glucose)
Autotrophs- inorganic carbon source (usu CO2)
Carbon Source
200
The majority of heterotrophs; glucose or organic compounds are used for getting BOTH chemical energy and a carbon source
ChemoHeterotrophs
200
solutions that have identical concentrations of solute
Isotonic
200
Movement from high to love concentration; continues until movement in both directions are EQUAL
Simple Diffusion.
200
Liquids- oil or molecules in solution enter; projection from the membrane (microvilli) surround the fluid and bring it into cell in a vesicle
Pinocytosis
300
Photo- light as energy source
Chemo- chemical energy source
Energy source
300
Decomposers-feed on dead organic matter, free living (ex. bacteria and fungi)
Saprobes
300
Solutions with GREATER solute concentration; cell loses water..shrinks (plasmolysis)
Hypertonic
300
Transported substance binds to a carrier protein; carrier proteins bind/transport only a single type of molecule. (glucose, amino acids, sugars)
Facilitated Diffusion
300
Optimal <15 degrees C (cold) ex. ocean, snowfield
Psychrophiles
400
Photosynthesis; converts light energy into chemical energy, inorganic carbon source into organic carbon source
PhotoAutotrophs
400
Live on or in the body of the host- parasites benefit/host harmed; Are pathogens (ex viruses, bacteria, fungi) live in isotonic
Parasites
400
Solutions with LESSER solute concentration; cell gains water..swollen (Turgid, it may lyse)
Hypotonic
400
Move UP or AGAINST the concentration gradient (low to high); requires ATP & carrier protein. Uses this to concentrate nutrients inside (Sugars,amino acids)
Active Transport
400
Optimal 15-30 degrees C (grow slowly in cold) ex. food spoilage in fridge
Psychrotrophs
500
Chemical energy can be organic or inorganic; inorganic carbon source (bacteria/archaea)
ChemoAutotrophs
500
2 main categories that obtain their organic nutrients differently
Saprobes and Parasites
500
Bacteria that can live in very high salt environments (hypertonic)
Halophillic
500
Transport of large molecules, particles, or liquids across the membrane.
Bulk Transport (endocytosis)
500
Optimal 20-40 degrees C; most common type of microbe, causes food spoilage (can survive/multiply) most likely to cause human disease.
