|
Why are the carotenoid collors (like red, orange, brown) visible in leaves in the fall, but not other times?
|
Chlorophyll production is stopped.
|
|

|
|
Who carefully MEASURED the mass of a growing plant and concluded the INCREASE came from water?
|
Jan Van HELMONT
|
|
|
How do other colored pigments like the carotenoids help cholorphyll carry out photosynthesis?

|
slow or stop
|
|
|
Why do most plants appear green?
|
Chlorophyll refects green light
