7.1.3 Adaptations

• Match the type of adaptation with its definition:

  Structural ↔️ Physical features of an organism

  Behavioral ↔️ Actions or responses of an organism

  Physiological ↔️ Internal processes of an organism
• Adaptations allow organisms to thrive in their habitats by helping them obtain food, avoid predators, and reproduce successfully.


  True
• What is the purpose of thick, waxy leaves in desert plants?

  Reduce water loss
• What physiological adaptation allows cacti to survive in dry climates?

  Minimal water photosynthesis
• A bear hibernating in winter is an example of a behavioral adaptation.


  True
• Behavioral adaptations are actions or responses that help an organism survive.

  True
• Behavioral adaptations in plants include leaves that fold up at night to reduce water loss.

  True
• Birds migrating south for warmer climates is an example of a behavioral adaptation.

  True
• The internal processes that allow desert animals to conserve water are examples of physiological adaptations.
• What are adaptations?

  Survival and reproduction traits
• What is an example of a structural adaptation?

  Camel's hump
• What is an example of a structural adaptation in plants?

  Cactus thick stem
• Order the following examples of behavioral adaptations in plants:

  1️⃣ Leaves fold up or close at night

  2️⃣ Flowers open and close at specific times
• What is the primary role of adaptations in an organism's life?

  Survive and reproduce
• Match the type of adaptation with its example:

  Structural ↔️ Camel's hump

  Behavioral ↔️ Bear hibernating

  Physiological ↔️ Cactus storing water
• The ability of a cactus to store water in its stems is a physiological adaptation.
• The ability of cacti to photosynthesize using minimal water is a physiological adaptation.
• The ability of desert animals to conserve water is a physiological adaptation.
• Adaptations help an organism survive and reproduce in its environment. environment

• A plant closing its leaves at night is an example of a behavioral adaptation. behavioral
• Match the type of adaptation with its plant example:

  Structural ↔️ Thorns on stems

  Behavioral ↔️ Flowers open and close

  Physiological ↔️ Photosynthesis with minimal water
• A camel's hump, which stores fat, is an example of a structural adaptation.
• What is a structural adaptation?

  Physical feature for survival
• What structural adaptation do desert plants have to reduce water loss?

  Thick, waxy leaves
• What structural adaptation do arctic animals have to stay warm?

  Thick fur
• Why is thick fur a crucial structural adaptation for arctic animals?

  Keeps them warm
