Answer:
The correct answer is : Mineral deficiency symptoms vary with the mobility of the mineral within the plant.
Explanation:
Nutrients/Minerals essential for the plant growth may vary in their ability to move within the plant. If we are aware about their mobility, it can be helpful in diagnosing deficiency problems.
After entering the plants, minerals are transported to the area of need, usually the growing parts. Some nutrients become immobile , while some are re mobilized. Immobile doesn't leave their original location, while re mobilized nutrients, leave their original location and move to area where they are required the most. After knowing, which elements are mobile or immobile in nature, it can help us in identifying Mineral deficiency symptoms.
As immobile minerals do not leave their place, so when any deficiency appears, it will first be noticed in new growth but when mobile nutrients are limited, they are moved from older parts of the plant to where they are required the most, thus causing deficiency in older growth.
Example:
- Nitrogen, Phosphorus, Potassium are mobile
- Iron, Boron, Calcium are immobile.
