The food stored in them provides nourishment during dormancy period. Under specific condition, the stem performs special functions. Storage of food: Underground stems are modified for storage of food. In Ginger, the underground stem grows parallel to the ground surface and it becomes fleshy through storage of food. In the axils of the underground scaly leaves of Potato plant branches develop. They store food in their apical regions which become round or oval.
These are called tubers. Vegetative Propagation: These modifications are of subaerial stems.
A part of the stem is underground and a remaining part is above ground. In Nephrolepis and Strawberry, branches arising from basal regions grow obliquely like arches, come in contact with ground and produce new plants. It involves the studies of all kinds of cells and their behaviour.
Molecular Biology The cell consists of large number of micro and macro molecules such as nucleic acids, proteins, lipids etc.
The interaction between these bio-chemical molecules results into life and all these studies of cells at molecular level are included under the branch known as Molecular Biology. It involves the studies of composition and mechanism of synthesis of the biomolecules of cells. Physiology Plants and animals perform life processes in a similar fashion.
For example digestion, respiration, excretion etc. In addition, plants also perform photosynthesis.
All these life activities are the consequences of bio-chemical reactions that occur inside the cell. The detailed study of these reactions is known as Physiology. Studying these books in addition to the prescribed school books gives the student an overview of the complete CBSE syllabus an the concepts which are most likely to be tested in the examinations.
