Question

what happens when we color black in a leaf in a plant?

Answer 1

Answer:

Black leaves likely overheat more than green leaves. Also, absorbing different wavelengths depends on the pigment molecules in the plant and how much energy can be harvested from that wavelength. For example, blue light has a lot of energy (think UV and sunburns) while red light has lower energy (infrared/heat waves).

Answer 2

Answer:

Leaf pigment concentrations

Irrespective of the light environment in which plants had grown, the black leaves had higher chlorophyll and anthocyanin contents than did the green leaves
