Plant and animal adaptations allow organisms to survive and reproduce in their environments. Adaptations occur at the cellular level in response to environmental changes. Some key plant adaptations include phototropism (response to light), hydrotropism (response to water), and gravitropism (response to gravity). Animal adaptations include camouflage to blend in with surroundings, mimicry to resemble other organisms for protection, and insulation or fat storage to regulate body temperature in hot and cold climates. Migration allows some species to track availability of food and favorable climates throughout the seasons.

1. Plant and animal adaptationsScience 6Mrs. 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. AdaptationsTropism… 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 plantsPhototropism – response toward lightHydrotropism – response toward waterGravitropism – response to gravity

5. PhototropismPlants react to sunlight as a response to carry out photosynthesis.

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

7. Phototropism

8. HydrotropismPlants 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 plantsDessert 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. CamouflageAn 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. MimicryTo its shapeTo its color

16. Adaptations to colder climatesInsulation – refers to a material that does not conduct heat well.Examples:Birds – feathersWhales – blubberSome 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

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  HuntingBe organizeCooperateLearned behavior

21. MigrationMeans to move from one place to another.Reasons:Availability of foodChanges in climateMating Give birth

22. MigrationMost 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.
