Adaptation Flashcards
What are adaptations
An inherited characteristic that helps an organism to survive long enough to reproduce more successfully in its changing environment and can either be structural or behavioural
What are Behavioural Adaptations
Ways an organism act to help them survive in their environment. For example, migration, hibernation, warning calls, mating dances, hunting in packs
What are Structural Adaptations
Actual body parts or coloration that help an organism survive in their environment. For example, camouflage, mimicry, bent hind legs, sharp teeth and claws, body structures
Behavioural Animal Adaptations
Migration Hibernation Living in groups Tool use Playing dead Calling Threatening gestures
Structural Animal Adaptations
Camouflage/ Colouration Mimicry Bent hind legs Eye location Teeth sharpness
Define Physiological Adaptation
Internal systematic responses to external stimuli in order to help an organism maintain homeostasis
Behavioural Plant Adaptations
Tropism
Dormancy
Gravitropism
Phototropism
What is tropism
movement of a plant toward or away from a stimulus. Toward is called positive, away is called negative
Define Dormancy
Many plants go dormant in the winter. Fall is the time of year when plants are preparing for dormancy
Define Phototropism
When the plant senses light and the shoots (stems & leaves) grow toward the light source. This is a positive tropism because the plant is growing toward the stimulus
Define Gravitropism
When growth of a plant changes in response to direction of gravity
