Answer 2

Answer:

All metabolic activities of life such as respiration, digestion, excretion and reproduction take place at the cellular level. Cells contain genetic materials, which play an important role in the transfer of.hereditary characters from parents to offspring. Cells of multicellular organisms are grouped to formmtissues, which are further organised to form organs. Organs, in turn, form organ systems and organ.systems work together to form what an organism is in its totality. Thus, cells are the basic building structural and functional units of life.
