Warm up 10/21Turgor Pressure

• WYW Explain how forces and motions affect an
  organisms 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.

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

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
