Van Helmont showed that plants get bigger with
out eating. He incorrectly concluded that it was
the water that caused the increase in mass.
Priestley determined that plants give off oxygen.
Ingenhousz discovered that light was necessary
for plants to produce oxygen.

Products
Where do the reactants come from?
Chloroplast: Where photosynthesis takes place.
Located in the cytoplasm of the plant cell.
Chlorophyll: Captures energy from light. Makes plants
green.
Location: thylakoid
☼ Occur in the chloroplast when there is light.
Main idea: Make ATP and oxygen from water and light
H2O is split causing an ATP molecule to form & release
O2. The H from the water and the ATP is used in the
next reaction.
Reaction detail:
+ H2O
H + ATP + O2
Location: stroma
☼No light needed (AKA dark reaction)
Main idea: Make glucose from hydrogen, carbon dioxide &
ATP
CO2 is split, rearranged, & bonded to H to make a 3-carbon
compound. This uses the ATP from the last reaction. The 3
carbon compounds are joined making C6H12O6
Reaction detail:
CO2 + H + ATP
C6H12O6

We call the glucose that is produced “SAP”
Glucose is transported from the chloroplasts
to the rest of the plant via the Phloem.
Maple Syrup from tree sap


Energy for growth and reproduction of the
plant
To make starch called cellulose
Starch and simple sugars are stored in fruits,
vegetables, seeds, and grains. Here they may
be used by the plant or eaten by consumers.

Photosynthesis is the process of converting light,
carbon dioxide, and water into glucose and oxygen.
Glucose, a carbohydrate, can be stored as a starch
for use later or be used to make cellulose for the cell
walls of the plant.
In a plant the glucose is known as sap. It is
transported around the plant via tubes called phloem.
Glucose is later converted into ATP in the
mitochondria by the process of cellular respiration.
