2.) Can you describe the role that osmosis plays in plant transport mechanisms? ----Describe how osmosis helps with transport in:
i.
Xylem-
ii.
Phloem-
3.) Can you illustrate the movement of water and nutrients from the roots to leaves?// Can
you illustrate the movement of organic compounds from the leaves to other plant parts? ---- Label on the pictures below where gas exchange, photosynthesis, water uptake, and
transpiration occur. Also, Where do the plant sugars originate? How will they flow to
other parts of the plant?:

4.) Can you illustrate the mechanism of open and closing of stomata? ----- Describe how a
stomata will open and close. What will cause it to happen? Draw a before and after
picture and be able to describe the mechanism that causes the stomata to open or close:
5.) Can you describe how physical forces contribute to the movement of water molecules
(Cohesion-Tension theory)? ----- How do adhesion and cohesion allow water to move
through the xylem? Explain how a molecule of water gets from the roots to the leaves:
