All Flashcards
What is environmental sensing?
The ability of organisms to detect and respond to environmental changes, crucial for survival and reproduction.
What is photoperiodism?
A plant's response to day length, regulating growth and flowering.
What is phototropism?
A plant's growth towards a light source to maximize photosynthesis.
What is taxis?
Directional movement of an animal towards or away from a stimulus.
What is kinesis?
A change in an animal's movement rate or direction in response to a stimulus.
What is the fight-or-flight response?
A physiological reaction to danger, preparing the body for action through adrenaline release and increased heart rate.
What is the effect of increased adrenaline release during the fight-or-flight response?
Increased heart rate and preparation of the body for action.
What is the effect of photoperiod on plant flowering?
It regulates the timing of flowering in plants based on day length.
What is the effect of communication within a species?
Protection of individuals, warning of danger, and increased survival rates.
What is the effect of natural selection on environmental responses?
Favors behaviors that increase survival and reproductive success.
What is the effect of cooperative behavior on fitness?
Increases fitness for individuals and populations involved.
What are the differences between behavioral and physiological mechanisms in environmental response?
Behavioral: Actions taken in response to environment (e.g., migration). Physiological: Internal changes like gene expression, hormone release (e.g., fur color change).
What are the key differences between taxis and kinesis?
Taxis: Directional movement toward or away from a stimulus. Kinesis: Change in movement rate/direction in response to a stimulus.
What are the differences between nocturnal and diurnal activity?
Nocturnal: Active at night (e.g., bats). Diurnal: Active during the day (e.g., lions).
Compare short-day and long-day plants in terms of flowering.
Short-day plants: Flower when days are short. Long-day plants: Flower when days are long.
