1. Warm up 10/21 Turgor Pressure
WYW: Explain how forces and motions affect an organism’s response to internal and external stimuli to environment.
L.C.: Our bodies require force and motion to facilitate involuntary and voluntary response to sustain homeostasis and perform life functions.

2. Tugor pressure

3. Think-Pair-Share
What is force and motion and what role does it play in everyday life?
How does pressure affect an organism?
What can you infer about a plants turgor pressure?
What is tropism and how does environmental stimuli affect its function?
How does force and motion, turgor pressure and stimuli all relate?

4. Forces in Plants C-Notes

5. What differences do you notice in these two plants?
This is caused by changes in turgor pressure.

6. What is turgor pressure?
Outward force in a plant cell when the vacuoles fill up with water, causing the cell membrane to push against the cell wall.
This plant has
HIGH turgor pressure.

7. Why is turgor pressure important in plants?
Gives them the rigidness to stand straight and continue normal cellular functions
Without normal turgor pressure, plants begin to wilt
This plant has
LOW turgor pressure.

8. What does it mean to wilt?
To wilt means to droop, become shriveled in size and shape, and to lose strength
Wilting does not mean the plant has died

9. What is emergence of seedlings?
An outward force that seedling plants put on their surroundings in order to emerge, or rise up
