Introduction (background)

5

 
Discuss STRUCTURE= FUNCITON: Include diagrams to accompany your discussions.    
Mechanisms for controlling water flow Basically, how do plants control their concentration gradients!!    
Info on the evolutionary significance of adaptations    

Results

 

 

    Data Tables: 2 minimum

A) transpiration

c) Stoma results per variable

 

 

        Data correctly represented, units, not confusing

2

 

        Data tables labeled with title

    Graph

 

 

        Title descriptive

1

 

        axes labeled, variables correctly identified

        If x-y scatter, show trend line and equation for Vmax you may not do a scatter

2

 

 

 

 

    Calculations : answers boxed leave a space in your report and you can go in and hand write . you must show your work!

a) biomass g/cm2 and rate per unit time

b) max rate of transpiration per trial

Trend Paragraph (maybe try this underneath each Figure)

 

 

Describes what is in the data tables and graphs. Include chi square and/or slopes for trails and stomata inquiry. Split into two many paragraphs

Conclusion: “Why do you see what you see?” in general, Is your discussion clear, does it flow, do you support yourself with evidence?

        2

 

        Relates background information and results (In your conclusion, include a discussion about how structure = function involving all the mechanisms plants can control water flow: bulk, passive, active, cotransport)
