Question

A deficiency of which element may lead to the yellowing of the leaves?

Answer 1

A deficiency of the element nitrogen may lead to the yellowing of leaves. This is because nitrogen is an essential nutrient for plant growth and is required for the production of chlorophyll. Without enough nitrogen, plants cannot produce enough chlorophyll, causing their leaves to turn yellow.

Answer 2

A deficiency of iron may lead to the yellowing of leaves, a condition known as chlorosis. Iron is an essential micronutrient that plays a crucial role in the production of chlorophyll, which gives leaves their green color and is necessary for photosynthesis. When iron is lacking, chlorophyll production decreases, causing the leaves to turn yellow or pale.
