Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis.

Magnesium is found in algal pigments (known as chlorophyll) and is used in the metabolism of plants, algae, fungi, and bacteria.

Magnesium is found in many enzymes in both plants and animals. An enzyme is a catalyst in a living organism. It speeds up the rate at which certain changes

Without magnesium it would die because it would not be able to photosynthesise. So it would not have any food which is glucose as energy for growth and repair. The magnesium is needed so that the chlorophyll in the chloroplasts can capture the sun's light energy and use it for photosynthesis.
