1. Plant Adaptations

2. Common Plant Parts
There are more than half a million different types of plants, and even though they look different, they all have some common parts.
Most plants have:
roots
stems
leaves
flowers
seeds

3. Common Plant Parts
Plants also have adaptations that make it easier for them to live in their environment.

4. obtaining food Root functions
Act as anchors to keep the plant in the ground.
Take in water an minerals from the soil.
Some roots store food.

5. obtaining food Root adaptations
Roots must adapt to many different environments
Spread out and create a shallow root system
Grow a deep tap root
Grow above ground to support the tree
Store food for later use

6. obtaining food Leaf functions To gather sunlight for photosynthesis
To absorb some water and carbon dioxide
To protect the plant
Leaves have many shapes and sizes, all depending on the environment and how much sunlight the plant needs.

7. obtaining food
To gather sunlight for photosynthesis

8. movement Plant can move in response to some stimuli. gravitropism
thigmotropism
phototropism
hydrortopism

9. protection Stem functions
Hold the plant upright and support the leaves
Carry water, minerals and food around the plant
Defend the plant against consumers

10. protection Stems and trunks must adapt to many different environments
Rigid and made of bark
Flexible and not made of bark
Have xylem to carry water and food around the plant
Defenses against consumers

11. reproduction Flower functions Attract pollinators
Contains the reproductive parts of the plant

12. reproduction Attract pollinators
Mimics a female insect to attract a male insect
Attract pollinators
Smells like rotten meat to attract flies
Smells sweet to attract bees

13. reproduction
Seed functions
Protect the seedling
Help the seed to move

14. reproduction Help the seed to move Projectile-seeds thrown from plant
Burrs-stick to animals
Dispersal by water
Dispersal by wind
Seeds pass through a digestive track

15. 3 Need-to-Know Examples of Internal Adaptations
Hollow bones in Birds
Gills in Fish
Xylem in Plants

16. Hollow Bones in Birds

17. Hollow Bones in Birds

18. Hollow Bones in Birds Internal Structure: Hollow Bones Function:
Hollow bones is just one of the advantages birds have gained through evolution. This makes them light, and a light body allows them to fly faster, using less energy.
It takes a lot of energy to fly. The more a bird weighs,
the more energy it takes to fly.
Eagles, for example, have a lightweight frame that gives them maximum strength with the least possible amount of weight.
In fact, the weight of an eagle's skeleton is only half a pound.

19. Gills in Fish

20. Gills in Fish Internal Structure: Gills Function:
Gills are the respiratory organs of fish.
First, a fish swallows water through its mouth. Then the water flows over the gills.
The gills take out oxygen from the water which passes back out of the fish.
The oxygen is then absorbed through the capillaries into the blood stream of the fish.

21. Xylem In Plants

22. Xylem In Plants

23. Xylem In Plants Internal Structure: Xylem Function:
Part of a plant's vascular system that transports water and minerals from the roots to the rest of the plant and furnishes support.
The xylem makes up the major part of a stem or root and the wood of a tree.
The xylem consists of special water-conducting
tissues made up mostly of several types of narrow,
long, hollow cells.

24. Internal Adaptations of an Archer Fish

25. In the quiet waters of the Orient, there is an unusual fish known as the Archer fish. It is unlike any other fish in that it finds its prey outside of the water.
The archer fish are known for their habit of preying on land-based insects and other small animals by literally shooting them down with water droplets from their specialized mouths.

27. Adaptation and Environmental Change
If an organism’s environment changes, the characteristics that it has inherited will determine if it can adapt and survive.
pandas cannot adapt well to new environments
coyotes easily adapt to any environment
