Chapter-1. NUTRITION IN PLANTS.

Nutrients :- The components of food like carbohydrates, fats, proteins vitamins and minerals are called nutrients.Nutrients help living organisms i) To build their bodies. ii) To grow. iii) To repair the damaged parts of their bodies. iv) To provide energy to carry out life processes..

Enzymes act as catalysts for enzymatic reactions. numa•t ron plays an important role in e production of amino acids and the development Of flowers and fruits. Manganese is crucial for activating enzymes. It is also essential for water splitting, which is the first step of photosynthesis..

5) Synthesis of proteins :- The soil has some bacteria which convert nitrogen from the air into usable nitrogen in the soil. Farmers also add fertilisers containig nitrogen into the soil. Plants absorb this nitrogen from the soil along with water and other constituents to prepare proteins and fats..

Insectivorous plants:- are plants which feed on insects. Eg:-Pitcher plant. The leaf of the pitcher plant is modified into a pitcher.The end of the pitcher has a lid which can open and close. When an insect enters the pitcher, the lid closes. The insect is then digested by digestive juices inside the pitcher..

7) How nutrients are replenished in the soil :-Plants absorb nutrients from the soil. So the nutrients in the soil decreases. So farmers add manures and fertilisers to the soil to increase the nutrients in the soil.The bacterium called rhizobium which lives in the roots of leguminous plants like grams, peas, beans etc. converts nitrogen from the air into soluble form in the soil and makes the soil rich in nitrogen.In return the plant provides food and shelter to the bacteria. So they have a symbiotic relationship..
