plants will remain healthy when exposed to light 24 hours a day

Can plants recover from too much sun?
Plants
recover energy
from the sun with the help of chlorophyll and carotenoid, two photon-capturing molecules. But if the plants are exposed to too much sun, these molecules engross more energy than they can handle and create reactive species of oxygen that can destroy the plant.
Is light through a window considered direct sunlight?
Light through a window
is not direct sunlight
as some of the light is diffused and reflected as it passes through the window, reducing its intensity. Light through a window is the most direct form of light available indoors, but is usually at least 50% less intense than direct sunlight outdoors.
