The cell is the fundamental structural and functional unit of living organisms. Cells need energy for active transport, to move molecules between the environment and the cells across cells or within cells. Cells obtain energy by oxidation ..

Undifferentiated cells or stem cells are unspecialised cells, which give rise to new cells by mitotic divisions. These go to form new tissues or in the maintenance of existing tissues. Examples for these are the Malpighian layer in the epidermis of..

Lymphocytes are the main cells of the immune system. They arise from stem cells present in the liver in the foetus and in the bone marrow in the adult. Comparison of cell-mediated and humoral immunity Some of them continue their maturation in the bone marrow ..

>Mitosis occurs in all the living cells of the body of an organism. Hence it is called somatic cell division. Mitosis is described as equational division since the chromosome number of daughter cells will be same as that of the parent cell. Mitosis has an int..

Cell Potential or EMF of a Cell - The difference between the electrode potentials of two half cells is known as electromotive force or cell potential or cell volta..

Cell Theory - Two German biologists M.J.Schleiden (1838) and Theodore Schwann (1839) proposed the cell theory (or cell doctrine), which unified the ideas prevailing at that period on the organisation in plants and animals. The cell theory states that All livi..

At the cellular level, growth of multi cellular organisms is governed by two main activities Reproduction of individual cells of body by mitotic cell divisions Growth of cells by synthesizing new protoplasm. The interphase stage of the cell cycle is different..

Introduction - The cells that make up our body are so small that you would fit over 200 of them on the full stop at the end of this sentenc..
