1. Bell Work:
Grab a Life: Plants video questions sheet off of the front table.
Get out your homework or get it out of the basket and be ready to grade.

2. Objective:
SPI Analyze structural, behavioral, and physiological adaptations to predict which populations are likely to survive in a particular environment.

3. Prior Knowledge How have plants survived on Earth for so many years?
What are some of the struggles plants face in obtaining daily needs like sunlight, water, space, etc.

4. Life: Plants
Today we will learn how plants have adapted to survive environmental pressures.
Be prepared to:
Describe how specific species of plants have adapted to survive in their habitats.

5. BELL WORK Grab one of each sheet off of the front table.
Define the following terms. Be sure to include what it is, what instrument you use to measure it, and in what units of measurement.
MASS-
WEIGHT-
VOLUME-
DENSITY-

6. OBJECTIVE:
OBJECTIVE: Analyze structural, behavioral, and physiological adaptations to predict which populations are likely to survive in a particular environment.

7. Plant Adaptations

8. Types of Adaptations
Structural adaptations are traits that are part of the plant’s structure (external).
Behavioral adaptations are the way something acts naturally or by instinct.
Physiological adaptations is when a  plant may change its interior body parts chemically. (internal)

9. Structural Adaptations
Adaptations to get food
Leaves and stems absorb energy from the sun.

10. Behavioral Adaptations
Adaptations to get food
Plants lean or grow towards the sun.
Roots grow down into soil.
Vines climb up trees to catch sunlight.

11. Behavioral Adaptations
Adaptations to get food
Plants like the Venus fly trap, trap insects for food.

12. Structural Adaptations
Adaptations to get water and nutrients
Roots soak up water and nutrients from soil.

13. Behavioral Adaptations
Adaptations to get water and nutrients
Desert flowers can stay dormant for months, only coming to life when it rains.

14. Structural Adaptations
Adaptations for reproduction
Brightly colored flowers with nectar attract pollinators such as birds, bees and insects.

15. Structural Adaptations
Adaptations for reproduction
Sweet fruit attracts animals that spread seeds far away.
Some seeds are shaped to catch the wind.

16. Behavioral Adaptations
Adaptations for reproduction
Plants drop seeds to grow new offspring.

17. Structural Adaptations
Adaptations for defense
Spines and thorns protect plants from predators

18. Structural Adaptations
Adaptations for defense
Poison Ivy and Poison oak have toxins that give predators a painful itchy rash.

19. Plant Adaptations for different Biomes

20. Desert Adaptations
Small leaves or spines on desert plants conserve water.
Thick waxy skin holds in water.
Roots near the soils surface soak up rain water quickly before it evaporates.

21. Grassland Adaptations
Deep roots help plants survive prairie fires.
Narrow leaves lose less water than broad leaves.
Flexible stems bend in the wind.

22. Tundra Adaptations Small plants grow close to the ground for warmth.
Dark colored flowers absorb heat from the sun.
Fuzzy stems provide protection from wind.

23. Rainforest Adaptations
Smooth, slippery bark keeps vines from killing trees.
Slide shaped leaves lets rain run off so fungus doesn’t grow on plants.

24. Temperate Forest Adaptations
Thick bark protects trees and dropping leaves in winter conserves water and nutrients during cold winters.

25. Water Adaptations Flexible stems move with water currents.
Floating seeds spread offspring.

26. DISCUSSION
What is a structural or behavioral plant adaptation that allows it to get water and nutrients?
Adaptations for reproduction?
Adaptations for defense?
Desert adaptations???
Grassland adaptations?
Rainforest adaptations?
