In experiments on chloroplasts taken from baby spinach leaves and thale cress(a type of flower)‚ the researchers shows they can: make plants sensitive to certain stuff‚ so now they can now use them as sensors Improve the plants’ photosynthesis activity so they are at least three times more of use than normal
