1. Plant and animal adaptations Science 6 Mrs. Marlene Torres

2. An adaptation is… a change in an organism that help it survive and reproduce in its environment. This changes are produce as a response to changes in the environment and occur at cellular level. Adaptations

3. Adaptations Tropism… is the response of an organism toward or away from a stimulus. Remember: Stimulus is something that produce a response of an organism.

4. Tropisms in plants Phototropism – response toward light Hydrotropism – response toward water Gravitropism – response to gravity

5. Phototropism Plants react to sunlight as a response to carry out photosynthesis.

6. Auxins This are chemicals that can stimulate parts of a plant, to make it grow quickly or slowly.

7. Phototropism

8. Hydrotropism Plants response to moisture and look for the availability of water.

9. Plants response to gravity. This response can be either positive or negative. Positive Gravitropism -Roots grow down Negative Gravitropism – Stems grow upward against gravity. Gravitropism

10. Other adaptations in plants Dessert plants can store water from one rainfall to survive years of drought. Carnivorous plants are meat eating plants that have adaptive structures to capture and digest insects.

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. Thorns are another kind of adaptation of plants. Other adaptations in plants

12. Camouflage An appearance that makes something look like its surrounding; could be its shape or color. Example: Color Camouflage -Chameleon Shape Camouflage -Stick bug

14. Mimicry An adaptation in which the animal is protected against predators by its resemblance to another animal. It looks like, but it’s not!!

15. Mimicry To its shape To its color

16. Adaptations to colder climates Insulation – refers to a material that does not conduct heat well. Examples: Birds – feathers Whales – blubber Some mammals - fur

17. Animals must be able to get rid of excess heat. In desserts we can found: Fennec – have huge ears that provide a large surface area from which heat can escape. Camels – Their humps are made of fat, so they can live off this stored fat when food is scarce. *Other animals dig themselves to escape the heat of summer or the cold winter in the dessert. Adaptations to Hot Climates

18. The Fennec

19. Animals can respond by instinct or with the help of a learned behavior. An instinct… is an inherited behavior that is done automatically. An instinct can not be learned. Examples: Feed, built nests, attract mates, defend themselves. Behaviors and Migration

20. Everything that we done because we learned it, observing or assisted by someone else. Examples : In humans In other animals: Share  Hunting Be organize Cooperate Learned behavior

21. Migration Means to move from one place to another. Reasons: Availability of food Changes in climate Mating Give birth

22. Migration Most birds and some insects migrate to warm climates during the fall season. At this time of the year the temperature drops and the food available is reduced.
