They are often grouped according to the part of the plant that is eaten:. bulbs;. flowers;. fruit;. leaves;. roots; . seeds;. stem (stalk).. Peppers are the edible fruit of a plant. Bulbs. Some plants have bulbs which stay underground to store food for the plant when it is not growing. When the time is right, the bulb produces shoots which grow up through the soil.. Nitrogen cycle. . In . physico. -chemical process, the atmospheric nitrogen combines with oxygen during lightning or electrical discharges in the clouds and produces different nitrogen oxides. These nitrogen oxides get dissolved in rain water, and on reaching earth surface they react with mineral compounds to form nitrates and other nitrogenous compounds. 2. ). Ammonium (NH. 4. +. ).
