What happens when plants don’t get light?
When plants lack light, they don’t produce chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. Plant stems become “leggy,” meaning stems become long and thin and appear to be reaching toward the source of light.
What happens when a plant is kept in the dark?
The plant will die within a few hours as it cannot produce food without sunlight. The plant will become dormant, producing neither oxygen nor carbon dioxide. The plant will use its stored food to obtain energy and survive.
What happens to chlorophyll when there is no sunlight?
When chlorophyll is no longer being produced, the other pigments show through (for example, red, orange and yellow leaves in the fall). These pigment molecules all have the same basic function – to absorb specific colors (wavelengths) of light and convert that light energy into sugar.
