Question

Explain what would happen if:
(i) Excess fertilizers are added to soil.
(ii) Blood clots in the coronary artery.
(iii) Beta cells in the islets of langerhans are damanged.
(iv) Silicon emulsion is applied over the surface of leaves.
(v) Magnesium element is deficient in the soil

Answer 1

(i) Excess fertilizers will from a hypertonic solution in the soil. Exosmosis will then occur in the root hair cells and the plant will dry and die due to loss of water.

(ii) Coronary artery supplies blood to heart. So, if blood clot is formed, blood supply to heart muscles will stop. It will then result in myocardial infarction.

(iii) Damage of beta cells of Langerhans will result in the improper production of insulin. It will result in the type I diabetes.

(iv) Silicon emulsion over the surface of leaves will block the stomata and hence transpiration will be reduced.

(v) Without magnesium chlorophyll cannot capture energy and thus photosynthesis is hindered.
