Form and Function Flashcards
Autotrophic
takes energy from the sun
Heterotrophic
take energy from molecules
Prokaryotic
single celled
Eukaryotic
many celled
Vertebrates
animals with spine
Cytoskeletal
Having no cell walls
Surface area ratio
surface area doubles then the volume triples
Surface function
Gas and ion exchange with the outside
Basal metabolic rate
How much ATP an animal uses at rest, empty stomach, normal temperature and normal humidity
Oxidizing
Measuring the amount of oxygen being used per ml per hour per gram of body rate
Small animal advantages
Larger surface-to-volume ratio, less oxygen needed, less energy needed
Small animal disadvantages
Spend more energy to keep everything under control, slight changes make a bigger difference
Large animal advantages
Less gas exchange, better at maintaining set point, more stable internal environment
Large animal disadvangates
Smaller surface to volume ratio, more food required, more cells
Adaptations to increase surface
Folding, branching, flattening,
