cell specialization

Simple epithelium may sometimes become modified for some specific functions. Two such modifications are very common, namely, ciliated epithelium and glandular epithelium. Ciliated epithelium is always a modification of columnar epithelium. Here, the cells are characterized by the presence..

Spontaneous redox reactions are the metal displacement reactions. Therefore such reactions have been used for producing electricity. This is done by carrying out these reactions in specially designed units called electrochemical cells. An electrochemical cell is a dev..

Differentiation - Differentiation is the process by which the unspecialised embryonic cells change in structure and function during development and growth of an organism to form specialised cell types, tissues, and organs, distinct from one another. Differentiation makes ce..

Growth at the cellular level involves four stages Cell expansion: an increase in the size of the cell due to formation of new protoplasm. Cell division: the cells increase in number due to mitotic cell division Cell differentiation: the ..
