Question:
I recently grew kidney beans with my classes and one plant has two leaves that are completely yellow. ALL the other leaves are green. I was wondering why this occurred. IS there an absence of chlorophyll? is the plant an albino?


Replies:
Yellowing or chlorosis of leaves can be caused by age, mineral deficiencies due to soil nutrient availability, insects and fungi, and amount of light. Albino leaves would be white.
