Question

How do the leaves of poinsettia plants turn red?

Answer 1

Poinsettia:

1. A light-sensitive plant is a poinsettia.
2. Lack of light prevents the plant from producing chlorophyll, which gives the leaves their green color.

Poinsettia leaves turn red due to:

1. Red is the only color that will be created in complete darkness and the absence of light.
2. Photoperiodism, a phenomenon, that causes the leaves of Poinsettia plants to turn red.
3. A certain amount of light leads the leaves to undergo this process and change from green to red (other shade variations such as white, and pink).
