Plant And Animal Adaptation

  1. 1. Plant and animal adaptations<br />Science 6<br />Mrs. Marlene Torres<br />
  2. 2. An adaptation is… a change in an organism that help it survive and reproduce in its environment.<br />This changes are produce as a response to changes in the environment and occur at cellular level.<br />Adaptations<br />
  3. 3. Adaptations<br />Tropism… is the response of an organism toward or away from a stimulus.<br />Remember:<br />Stimulus is something that produce a response of an organism.<br />
  4. 4. Tropisms in plants<br />Phototropism – response toward light<br />Hydrotropism – response toward water<br />Gravitropism – response to gravity<br />
  5. 5. Phototropism<br />Plants react to sunlight <br /> as a response to carry out photosynthesis.<br />
  6. 6. Auxins<br />This are chemicals that can stimulate parts of a plant, to make it grow quickly or slowly.<br />
  7. 7. Phototropism<br />
  8. 8. Hydrotropism<br />Plants response to <br /> moisture and look <br /> for the availability <br /> of water.<br />
  9. 9. Plants response to gravity.<br />This response can be either positive or negative.<br />Positive Gravitropism -Roots grow down <br />Negative Gravitropism –<br /> Stems grow upward against gravity.<br />Gravitropism<br />
  10. 10. Other adaptations in plants<br />Dessert plants can store water from one rainfall to survive years of drought.<br />Carnivorous plants are meat eating plants that have adaptive structures to capture and digest insects.<br />
  11. 11. Some plants can produce secretions or oils, like the poison-ivy plant. If you pull it out from the ground may cause a severe rash.<br />Thorns are another <br /> kind of adaptation <br /> of plants.<br />Other adaptations in plants<br />
  12. 12. Camouflage<br />An appearance that makes something look like its surrounding; could be its shape or color.<br />Example:<br /> Color Camouflage <br /> -Chameleon<br /> Shape Camouflage <br /> -Stick bug<br />
  13. 13.
  14. 14. Mimicry <br />An adaptation in which the animal is protected against predators by its resemblance to another animal. <br />It looks like, but it’s not!!<br />
  15. 15. Mimicry<br />To its shape<br />To its color<br />
  16. 16. Adaptations to colder climates<br />Insulation – refers to a material that does not conduct heat well.<br />Examples:<br />Birds – feathers<br />Whales – blubber<br />Some mammals - fur<br />
  17. 17. Animals must be able to get rid of excess heat.<br />In desserts we can found:<br />Fennec – have huge ears that provide a large surface area from which heat can escape.<br />Camels – Their humps are made of fat, so they can live off this stored fat when food is scarce.<br />*Other animals dig themselves to escape the heat of summer or the cold winter in the dessert.<br />Adaptations to Hot Climates<br />
  18. 18. The Fennec<br />
  19. 19. Animals can respond by instinct or with the help of a learned behavior.<br />An instinct… is an inherited behavior that is done automatically.<br />An instinct can not be learned.<br />Examples: Feed, built nests, attract mates, defend themselves.<br />Behaviors and Migration<br />
  20. 20. Everything that we done because we learned it, observing or assisted by someone else.<br />Examples :<br />In humans In other animals:<br />Share  Hunting<br />Be organize<br />Cooperate<br />Learned behavior<br />
  21. 21. Migration<br />Means to move from one place to another.<br />Reasons:<br />Availability of food<br />Changes in climate<br />Mating <br />Give birth<br />
  22. 22. Migration<br />Most birds and some insects migrate to warm climates during the fall season. <br />At this time of the year the temperature drops and the food available is reduced.<br />
