In tubes which received light Photosynthesis happened as well as respiration so overall there was an __________ of carbon dioxide |
absorption |
|
|
Black paper stopped light reaching the leaf in so only respiration could happen. There is a net release of carbon dioxide and a net uptake of ... |
oxygen |
|
