Interpreting data on limiting factors (graph on effect of CO2 on plant growth in greenhouse - 2 lines, 1 without CO2, other with CO2)

- In the greenhouse with added CO2 plant growth was faster + on average they were larger after 8 weeks than they were o the control greenhouse - This was because the plants use CO2 to produce glucose by photosynthesis - The more CO2 , the more glucose produced, meaning they can respire more + have ATP for DNA replication, cell division + proteins synthesis
