1. Heredity and Function We have looked at genetics
We have identified plants and animals using their structures
Now, we will look at how genetics and function can effect adaptations

2. Heredity and Function
What are some genetic traits or adaptations we may see in animals over several generations.
What are some genetic traits or adaptations we may see in plants over several generations.

3. Structure and Function
The structure and function of plant
parts show evidence of adaptation.
Examples Include:
Defenses against consumers
Ways to attract pollinators
Seed dispersal to ensure survival

4. Adaptations Look at the four “cards” on your desk
Think about what each one means
Read the following statement:
The process that best allows a species or population of organisms to survive is _____________________________
Think about the statement, and choose which card you think best answers that question.

5. Plant Adaptations

6. Survival
As you watch this presentation, focus on how variations, adaptations, or behaviors enhance a plants’ survival.
Include:
Roots Seeds
Stems Phototropism
Leaves Geotropism
Flower

7. Structure and Function
Comparing structure and function of parts and
behaviors helps us understand why variation is
necessary.
Structure is the form of an organism’s parts.
Example: A pedal is structured like
a landing strip for insects.
Function is what that part does.
Example: The function of a petal is to attract insects.

8. Plant Adaptations
What are some plant structures that help the plant survive?
List at least 3

9. 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

10. Obtaining Food/Nutrients
All plants must find and take in nutrients
food
carbon dioxide
water

11. Roots must adapt to their different environments.
Structure and Function:
Roots act as anchors to keep plants grounded.
Roots take in water and minerals from the soil through tiny root hairs.
Some roots can store food.

12. Roots
Some roots spread out along the ground in search of water in places where it rains often.
