Answer Key

1. Structure is the physical appearance of an organism, examples might include and animals legs or plants roots.
2. Answers will vary, students should describe the structures of a horse and dog in terms of size, features, materials and location.
3. A bats wing and a whale’s tale are similar in that they both are used for motion.
4. Function is that something does. Examples should describe how the structure is used.
5. Examples should describe the two structures in terms of size, features, materials and location.
6. Function is what something does. Examples should describe how the structures are used.
7. Answer may vary:

1. Chew food, attack/defense
2. Flight, motion
3. Gather nutrients, anchor plant
4. Function
5. Growth, survival, behavior, reproduction.
6. Roots absorb nutrients, leave produce food, stem provides support for growth.
7. Hide protects against the environment and provides camouflage, claws and teeth for defense, eyes spot danger
8. Flowers attract pollinators, seeds pass along genes to next generation
9. Legs provide movement for migration, reacts to the environment, communicates with others.
10. Structures
11. Claws to gather food, mouth and teeth to chew food, legs to chase food
12. Spines to protect against foragers, thick skin to protect the plant, stem to hold water.
13. Physical features attract a mate, sex organs pass along genes to next generation.
14. Leaves grow towards the light, Stems react to the environment
15. Internal
16. Answers will vary but should describe internal functions that support movement such as muscles, nerves, bones, heart, ect.
17. Transport system, roots
18. Brain, muscles
19. Vocalizing (communication), hibernating
20. Seeds, reproductive parts
21. Internal, external
22. Digestive system, heart, lungs
23. Poison, storing extra water
24. Growing towards light, losing their leaves.
25. Reproductive organs
26. Sight, smell, hearing, touch & taste
27. Specialized receptors send specific information to the brain. The nose sends information about smells.
28. Bees are able to see ultraviolet light because they have specialized receptors.
29. Plants react to their environment by reacting when touched to protect themselves and by growing towards the sunlight.
30. Specific
31. Sensory integration is the combining of all the information received from the senses and it’s processing to make sense of the information.
32. Heightened
33. Eyes, ears, nose, tongue. They send specific information and feedback.
34. Plants respond to the sunlight by growing towards it through phototropism.
35. The brain decodes all the messages from receptors and makes sense of the information.
36. Different
37. Neurons and nerves
38. The lower part of the brain (brain stem) routes information to the correct region of the brain.
39. Actions are sent out from the brain.
40. Reflexes are automatic and do not require any thought, while actions require thought.
41. Information moves over a series of neurons and nerves.
42. The brain not only receives signals from all over the body, it also sends out signals to the rest of the body.
43. Instincts are something you are innately born with, such as the ability to breathe or eat.
