7. Importance of magnesium in plants
Magnesium is a macronutrient that is necessary to both plant growth and health.
It is involved in several different processes, including photosynthesis, which nearly all living organisms are dependent on.

8. Importance of magnesium in plants
Many enzymes in plant cells require magnesium in order to perform properly. However, the most important role of magnesium is as the central atom in the chlorophyll molecule.
Chlorophyll is the pigment that gives plants their green color and carries out the process of photosynthesis. It also aids in the activation of many plant enzymes needed for growth and contributes to protein synthesis.

10. Magnesium deficiency Symptoms
A magnesium-deficient crop will tend to have a pale overall color.

11. Magnesium deficiency Symptoms
Purple or red-brown pigment may appear of the lower on older leaves.

12. Magnesium deficiency Symptoms
Chlorosis generally progresses to yellowing and necrosis of the oldest leaves.
Leaves may become entirely yellow and wilted before browning off, or necrosis may develop on interveinal and marginal tissues without prior chlorosis.
Most commonly, localised yellowing precedes necrotic lesions, which spread from interveinal zones.

13. Magnesium deficiency Symptoms
The vines of magnesium-deficient plants may become thin and twining, with lengthened internodes, a response similar to etiolation.
