In general, plants aren't damaged from receiving too much light. In some cases, if the sun is shining directly on a plant for too long, the leaves, bark and fruits can become scalded. This kind of scalding is initiated by a general increase in temperature in the leaf tissues. If kept at too high a temperature, the plant can no longer function properly. More likely is damage as a result of insufficient light. Large shrubs, bushes and trees often fall victim to this. Typically when newly grown branches on the outside prevent concealed plant foliage from receiving enough light. Too much light can also damage potato tubers, making them inedible. Tubers should always be stored in a cool area away from direct light.
Leaves can turn yellow.
Defoliation may occur.
Potato tubers can be rendered inedible if left in direct light.
