The green pigment in plants, chlorophyll, is not produced when there is insufficient light, and as a result, plants can change color from pale green to yellow to white.
When a plant becomes "leggy," it develops long, slender stems that resemble they are reaching for the sun.
The plant develops lengthy intervals between the leaf nodes (the place where a leaf shoots out from the stem) on stems when there is insufficient light.
Without enough light, plants may also lose their leaves, particularly older ones.
A plant with variegated leaves (white and green leaves) may eventually turn all-green.
Some flowering plants may not develop flower buds.
Too much light may cause plants to have burned and browned leaves.
