the plant would suffocate
|
|
What affects the rate where photosynthensis occurs?
|
water availability, temperature, and the amount of light

|
What is a granum?
|
stacks of thylakoids
|
|
What is the region outside of the thylakoids in the chloroplasts called?
|
stroma
|
|
What are the two stages of photosynthesis?
|
light and dark reactions
|
|
What are the reactants and products of the light reaction?
|
reactants: light, h2o
products: o2 |

What were van Helmont's discoveries?
|
she discovered that there are certain materials out of the soil that are vital to the growth of plants
|
|
What were Preistly's discoveries?
|
he discovered that plants give off a substance (oxygen) that allowed candles to burn longer when a jar is placed over them
|
|
What were Ingenhousz's discoveries?
|
she discovered that the plant must have light to give off the substance (oxygen) in Preistly's experiment
