What is respiration in plants?
The process of plants using glucose to generate energy needed for growth and repair. The opposite of photosynthesis.
200
Which two tissues make up the vascular bundle of a plant?
200
Describe the procedure and test result for determining if a leaf contains starch.
Positive result: Blue/Black Negative result: Orange
200
State the balanced chemical equation for photosynthesis.
6CO2 + 6H2O --> C6H12O6 + 6O2
300
Define Limiting Factor
Something present in the environment in such short supply that it restricts life processes.
300

300
300
Identify and explain the limiting factors of photosynthesis.
400
What are mineral ions?
Electrically charged minerals that are absorbed by plants through the roots through active transport. Examples include magnesium and Nitrate ions.

A student investigates the rate of photosynthesis of an aquatic plant. He places some hydrogen carbonate in a testube with a leaf and leaves it in a dark closet for 24 hours.
When the student returns to observe his testube, what color should it be and why?
Yellow, because plant is respiring and expelling CO2
causing the indicator to change from red to yellow. 
400
Provide 3 adaptations that leaves have making them optimal for carrying out photosynthesis.
500
What is the chemical formula for hydrogen carbonate and what is it used for in plant nutrition studies?
HCO3-
It is used as an indicator solution for pH and can be used to investigate gas exchange in aquatic plants.
500
Draw the pathway a CO2 molecule takes when entering a leaf during photosynthesis.
500
What investigation is the table below referring to? How would you carry out this investigation?
What conclusions can you draw from the data below?
500
List 5 different uses of converted glucose in plants.
