There are plenty of impurities in impure water in the form of soluble minerals that are dissolved in it. If this water is used as a solution culture to grow plants in hydroponics, these impurities will interfere with the experimental procedure used to detect the elements. Hence, pure water and purified nutrient salts are utilized in studies involving mineral nutrition using hydroponics.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3-explain-with-examples-macronutrients-micronutrients-beneficial-nutrients-toxic-elements-and-essential-elements\"><\/span><strong>3.

They are required in large amounts for plant growth. Ex: Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Sulphur, Potassium, calcium and magnesium.<\/p>\n<p>Micronutrients \u2013 are the trace elements present in less than 10mmole kg<sup>-1<\/sup>\u00a0of dry matter in plant. Example \u2013 manganese, copper, zinc, boron, nickel<\/p>\n<p>Beneficial elements \u2013 In addition to 17essential nutrients there are some beneficial elements required by higher plants in addition to micro and macronutrients. Ex: Sodium, Silicon, Cobalt and selenium.<\/p>\n<p>Toxic elements are those which are required in trace amount. Their deficiency causes diseases in plants and excess in such nutrients are toxic to plants. Ex: Sodium, Potassium, Magnesium .<\/p>\n<p>Essential elements \u2013 It is an element that directly interferes in the metabolism of the plant causing a specific deficiency symptom if not available to plants from an external source.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4-name-at-least-five-different-deficiency-symptoms-in-plants-describe-them-and-correlate-them-with-the-concerned-mineral-deficiency\"><\/span><strong>4.

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?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Plants which show symptoms of multiple nutrient deficiency grown in different sets in water culture. Set 1 , 2 and 3 are given three different nutrients and are grown in hydroponics by supplementing one of the different nutrients showing deficiency. If real deficient element is supplemented then the plant will grow normally without showing deficiency symptoms.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"6-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\"><\/span><strong>6. 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?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Mobility of a deficient element decides the appearance of symptoms. If the element is relatively immobile then symptoms appear in young parts and if the deficient element is mobile, then symptoms appear in older parts of the plant.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"7-how-are-the-minerals-absorbed-by-the-plants\"><\/span><strong>7. How are the minerals absorbed by the plants?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The process of absorption can be established in two main phases. In the first phase, an initial rapid uptake of ions occurs passively into the \u2018free space\u2019 or \u2018outer space\u2019 of cells \u2013 the apoplast. In the second phase of uptake, the ions are taken in slowly into the simplest of the cells -\u2018inner space\u2019 . The passive movement of ions into the apoplast usually takes place through ion-channels, the trans-membrane proteins that function as selective pores. The entry or exit of ions to and from the simplest requires the expenditure of metabolic energy and that is an active process. The movement of ions is usually called flux; the inward movement into the cells is influx and the outward movement, efflux.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"8-what-are-the-conditions-necessary-for-fixation-of-atmospheric-nitrogen-by-rhizobium-what-is-their-role-in-n2-fixation\"><\/span><strong>8.
