When a person wears the glasses outside during the day, the lenses（鏡片）darken and lighten depending on how sunny it is. Plants do the same thing, he said. But in plants the adjustment can take anywhere from 10 minutes to an hour. This makes it hard for plants to get the right amount of sunlight needed to create food. s protective system. Normally, this system is activated when a plant gets too much sunlight, said scientist Krishna Niyogi, coauthor of the study. When the plant senses the light, it gets rid of extra energy and creates more leaves. When the plant is in shade, the protective system is turned off, but the process is slow. s genes, the scientists were able to increase the amount of leaf growth on plants between 14 and 20 percent. s genes in order to make it use sunlight more quickly.
