,B CELL THEORY
SECURE


The cell is the fundamental unit of life. All organisms, whatever their type or size, are composed of cells. The modern theory of cellular organisation states:-
•All living things are composed of cells and cell products.
•New cells are formed only by the division of pre-existing cells
•The cell contains inherited information (genes), which is used as instructions for growth, functioning and development.
•The cell is the functioning unit of life; the metabolic reactions of life take place within the cells.
