______

II. Seasons, night-length and plants.

2.A.1.d.2.IE Reproduction and rearing of offspring require free energy beyond that used for maintenance and growth. Different organisms use various reproductive strategies in response to energy availability. IE: Seasonal reproduction in animals and plants; Life-history strategy (biennial plants)

2.C.2.a.IE Organisms respond to changes in their external environments. Organisms respond to changes in their environments through behavioral and physiological mechanisms. IE: Photoperiodism and phototropism in plants.

2.E.2.a.1 In plants, physiological events involve interactions between environmental stimuli and internal molecular signals. Phototropism, or the response to the presence of light.

2.E.2.a.2 Photoperiodism, or the response to change in length of the night, that results in flowering in long-day and short-day plants.

2.E.3.b.1 In phototropism in plants, changes in the light source lead to differential growth, resulting in maximum exposure of leaves to light for photosynthesis.

2.E.3.b.2 Inphotoperiodism in plants, changes in the length of night regulate flowering and preparation for winter.

IV. Feedback

2.C.1.a.IENegative feedback mechanisms maintain dynamic homeostasis for a particular condition (variable) by regulating physiological processes, returning the changing condition back to its target set point. IE: Plant responses to water limitations.

2.C.1.b.IE Positive feedback mechanisms amplify responses and processes in biological organisms. The variable initiating the response is moved farther away from the initial set-point. Amplification occurs when the stimulus is further activated which, in turn, initiates an additional response that produces system change. IE: Ripening of fruit.

2.D.2.c.IE Homeostatic control system in species of microbes, plants and animals support common ancestory. IE Osmoregulation in aquatic and terrestrial plants.

2.D.4.a.IE Plants and animals have a variety of chemical defenses against infections that affect dynamic homeostasis. Plants, invertebrates, and vertebrates have multiple, nonspecific immune responses. IE: Plant defenses against pathogens include molecular recognition systems with systemic responses; infection triggers chemical responses that destroy infected and adjacent cells, thus localizing the effects.

3.D.2.b.IE Cells communicate over short distances by using local regulators that target cells in the vicinity of the emitting cell. IE: Plant immune response.
