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?
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.
