Rhizome of ginger is like the roots of other plants that grows underground despite this fact ginger is a stem and not a root. Justify.

Ginger is a stem and not a root because

Why underground stem is different from roots.

What is the difference between underground stem and roots?

Justify the following statements on the basis of external features. Underground parts of a plant are not always roots

Potato which we eat is an underground part of a plant, however it can not be considered as root. Justify the given statement.

Read the following paragraph and answer the questions based on it. Rhizobium living in root nodules supply nitrates, nitrites and amino acids to that plant and in exchange get energy in the form of carbohydrates from it. Such a mutually beneficial relationship is called symbiosis. Rhizobium produce nitrogenous compounds from atmospheric nitrogen. However, for this process of nitrogen fixation, they need leguminous plants like beans, sweet pea, soyabean, etc. as ‘host’. Beans and pulses are rich in proteins due to the nitrogenous compounds made available by Rhizobium. After harvesting a leguminous crop, the left-over roots and other plant parts are deliberately dumped in farm soil to maintain its bacterial population. The use of Rhizobium has helped to reduce the use of chemical fertilizers and thereby their adverse effects. It has also helped to reduce expenses on fertilizers and thus works to the benefit of farmers. Why does left over roots and other plant parts are deliberately dumped in farm soil after harvesting a leguminous crop?
