Write five different linear equations in two variables and find three solutions for each of them?

Why is that in certain plants deficiency symptoms appear first in younger parts of the plant while in others they do so in mature organs?

Epidermal cells are often modified to perform specialised functions in plants. Name some of them and function they perform.

If a plant shows a symptom which could develop due to deficiency of more than one nutrient, how would you find out experimentally, the real deficient mineral element?
