All elements that are present in a plant need not be essential to its survival’. Comment.
Explanation Plants tend to absorb different kinds of nutrients such as magnesium, zinc, copper etc. from the soil. Again, some nutrients absorbed by plants are not essential for survival of plants. For example, plants that grow near radioactive material producing factory be likely to accumulate radioactive metals, which are not involved in the plants physiology and metabolism. Moreover, gold get mount up in plants that grow near gold mines. This clearly show radioactive metals, gold or selenium are not essential nutrients for the survival of plants but magnesium, zinc etc. are very much fundamental for plant growth. Final Answer Most of the nutrients that are present in soils are useful for plant and help in the physiological process of plants and metabolism. But plants grow near mines or radioactive material producing factories show different types of minerals like gold, radium that are not essential for plants.
