Scientists investigated glucose production by cells from a plant leaf.
The cells contained organelle Q. Some cells were treated so that the green pigment was removed from organelle Q. No other cell structures were affected.
All other conditions were kept the same.
| Light intensity in lux | Green pigment in organelle Q | Mean mass of glucose made in 6 hours in µg per 10 000 cells |
|---|---|---|
| 0 | present | 0.00 |
| 2000 | present | 0.24 |
| 10 000 | present | 0.86 |
| 10 000 | absent | 0.00 |
