plant minerals deficincy

Question 1

Name minerals required by a plant and their function

Answer 1

1- Magnesium: Making chlorophyll
2- Potassium: Healthy flower and leaves.
3- Nitrates: Mineral containing nitrogen used for healthy growth.
4- Phosphates: Mineral containing phosphorus used for healthy roots

Question 2

What is mineral deficiency?

Answer 2

When a plant doesn’t get enough minerals, it results in poor growth. This is called mineral deficiency.

Question 3

What happens if a plant has nitrates deficiency?

Answer 3

Poor growth. Older leaves will turn yellow

Question 4

What happens if a plant has magnesium deficiency.

Answer 4

Leaves will turn yellow because there is not enough chlorophyll being produced to give it the green pigment.

Question 5

What happens if a plant has phosphorus deficiency

Answer 5

Poor root growth and younger leaves will look purple.

Question 6

What happens if a plant has potassium deficiency

Answer 6

Leaves will be yellow with dead patches

Question 7

Explain the role of nitrates in plant growth.

Answer 7

Nitrates ( just like nitrogen) is involved in the making of amino acids. Amino acids join together to form proteins. Proteins are used for cell, leaves and shoots ( the above ground part of the plant) growth.

Question 8

True/False

Phosphorous is required to make chlorophyll.

Chlorophyll is found inside chloroplasts

Nitrates are required to make amino acids

Amino acids join together to make carbohydrates

Plants with nitrate deficiency have poor root growth

Plants with a magnesium deficiency are discoloured (pale yellow)

Potassium is required for healthy leaves and flowers

Fertilisers provide minerals to help plant growth

If a plant is deficient in any mineral, it has a mineral deficiency
