Limiting Factors: something present in the environment in such short supply that it restricts life processes.
-
As the amount of light increases, the rate of photosynthesis increases (a-b)

-
The carbon dioxide diffuses through the open stomata of a plant leaf, and water is taken up through the roots.
Chlorophyll is a green dye that traps light energy and converts it into chemical energy to form carbohydrates and their subsequent storage.
Glucose is used for respiration, energy storage, cellulose cell walls, and making proteins and sugars.

Leaf boiled in water for 2 minutes to break down cell walls, denature enzymes and allow for easier penetration by ethanol.
Warmed in ethanol until the leaf is colourless to extract chlorophyll, which would mask the observation
-
The leaf is placed on a white tile, and iodine is added. If starch is present, the colour will be blue-black; if absent, it will remain brown
Photosynthesis
Photosynthesis: the process by which plants manufacture carbohydrates from raw materials using energy from light.
