Self-evaluation• Figure out your grade without extra credit

and compare to the grade with it. Any surprises?

• Did you spend the time that you needed on the test?

• Did imposing a time requirement make you more likely to slow down and check your work? Why or Why not?

• How did you prepare for this test? How will you prepare next time?

Adaptation

  Response of an organism in order to survive in environment

  Organisms well adapted tend to survive better than those who are maladapted

  Can involve coloration, physical structures, behaviors, etc.

Plant Tropisms • Phototropisms-growth toward light• Because of Auxin-hormones that collect on the dark side of

the plant to elongate dark-side cells• Thigmotropism-growth in response to touch• Gravitropism-growth of stems upward, roots downward

– Because of amyloplasts-cells with starch grains that collect to “tell” the plant which way is up (like the otoliths in your ears)

• Chemotropism-growth of pollen tube• Nastic Movements-viewable movements in response to

stimuli–Thigomonastic: touch–Nyctinastic: daily light cycles (sunflowers

follow the sun)

Plant Hormones

• Auxins-cause cells to grow, stop sprouting/spreading and hold fruit to the plant until ripe

• Gibberellins-cause germination and growth of seedlings, increase fruit size, and can promote flowering 

   Ethylene-Ripens fruit   Abscisic Acid (ABA)-promotes dormancy,

blocks growth, stops effectiveness of other hormones

Animal Behavior

• Most behaviors of animals revolve around meeting the needs of these characteristics:

• Food gathering, protecting self, protecting young, Mating, rest, can you think of others?

• Many behaviors are adapted to the environment, just as physical characteristics are.

• Instincts (innate behaviors)are genetically inherited. Organisms exhibit them at birth.

• Reflexes are quick responses to stimuli, which the organism doesn’t think about or control.

• Learned Behaviors are acquired throughout an organism’s lifetime.

Examples of behavior

• Territory defense • Courtship• Hierarchies• Migration• Conditioning (Ivan Pavlov and his dogs)• Cooperation• Parental Care• Imprinting (Konrad Lorenz)• Why do these behaviors exist?

Rhythmic Behaviors • Circadian Rhythm-pre-programmed sleep/wake cycle in

animals• –Exists in spite of light/dark cycles• –Usually 24-hour cycle• –Controls cellular behavior as well as organismal behavior• –Also called a diurnal rhythm         Also called biological clocks• Annual Rhythms-like circadian rhythms but occur over the

course of a year         Includes estivation (summer inactivity) and hibernation

(winter inactivity)         Also includes tidal or lunar rhythms-behavior changes in

animals because of tides or moon cycles (interrelated)         Migration is also included

Plant Rhythms

• Photoperiodism-response of plants to varying amounts of daylight during yearo Works because of phytochrome-a pigment that

absorbs light and tells the plant whether or not there is light

o Short-day plants-flower in fall when there is less light

o Long-day plants-flower in spring when there is more light
