Behavioural Adaptations (HSC SSCE Biology): Flashcards

Actions in response to stimuli that help organisms survive

Pressure in plant cells keeping vacuoles full, pushes cell wall

Leaves fold inward quickly (defensive)

Lives in nitrogen-poor soils; needs nutrients esp. nitrogen

Animals whose body temp influenced by ambient temperature

State of much reduced activity during prolonged cold periods

$13^\circ\text{C}$ to $44^\circ\text{C}$

Animals that maintain relatively constant body temperature

Lick wrists where blood vessels near skin; evaporation cools

One stands guard, warns others of threats while group feeds
