|
|
What affects the rate where photosynthensis occurs?
|

|
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?
