Why do plants need magnesium?

Answer 1

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 plantsand 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.

Answer 2

Magnesium is very important to a plant. It is a macronutrient, and is needed mostly for chlorophyll in the plant. This is important because chlorophyll is needed for photosynthesis, which is needed for sugar in the plant.

Answer 3

magnesium the mineral used by plants to produce chlorophyll which is needed in order for photosynthesis to take place.

It depends on the use. In fact it is both fruit as well as vegetable.

Answer 4

Magnesium is found in chlorophyll in the same way that iron is found in haemoglobin.

Both types of pigment have a porphyrin ring associated with the protein. In haemoglobin, the porphyrin ring is chelating an Fe2+ ion, while in chlorophyll it is a Mg2+ ion.

Answer 5

Magnesium ions are needed by plants to make chlorophyll

Nitrate ions are needed by plants to make protein

Additional info: Enzymes are protein in nature.

it acts as catalyst to speed up chemical reaction without being used up at the end of the chemical reaction.

Only small amount of enzymes are needed to catalyse (speed up) chemical reactions

Thus, enzymes are needed in plants.

because magnesium is a vital commponent for photosynthesis

Answer 6

Plants need magnesium to carry out photosynthesis, as it is an essential component of chlorophyll. Magnesium is also crucial for enzyme activation and protein synthesis in plants. A deficiency of magnesium can result in yellowing leaves, stunted growth, and poor fruit development.

Answer 7

Magnesium ions are needed because they forms cholorophyll which gives green colour to the plant without it the leaves turns pale

Answer 8

magnesium is the central atom of the porphyrin ring of the chloroplast

it activates the enzymes of respiration and photosynthesis

Answer 9

Magnesium is an essential element in the chlorophyll molecule - therefore plants need it to survive.

Magnesium sulfate is commonly used to replenish the magnesium content in soil.
