Growth In metabolism we have seen that organic matter is collected from the environment and processed in the cell. In the process of growth, the cell organizes this material into its own structure. During growth the cell spends some amount of the energy created in the process of metabolism. Every organ has its own pattern of growth. This pattern depends upon the tissue of the organ. Growth of different organs leads to physical growth. Food is converted into organic matter which is then utilized for the growth of the body. Nonliving organisms do not show these characteristics. Reproduction A living thing has the ability to procreate when it matures through the process of reproduction. There are differences in the reproductive functions of higher animals and lower animals. In lower animals (as in unicellular animals like amebas and bacteria), reproduction merely extends the

In asexual reproduction only one parent is involved. So generally the produced cells are identical to the parent cell. In asexual reproduction, the rate of production of offspring is faster than in sexual reproduction. In higher or more complex organisms there is another type of reproduction called sexual reproduction. In sexual reproduction, two parents of opposite gender type are responsible for the formation of a new organism. During sexual reproduction, a new combination of genetic material (D.N.A.) occurs. This process is complex and takes more time than asexual reproduction. Nonliving things do not reproduce....

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
