Growth is an irreversible increase in size and weight of an organism. The cells of the body do not grow uniformly but differentially. The main types of growth are auxetic, multiplicative and accretionary. The human growth curve is sigmoid and is controlled by hormones. Regeneration is of ..

Cell is the structural and functional unit of the organism. Water is the principal constituent of plants and is essential for the maintenance of life, growth and development. Plants absorb water from the soil through their roots, transport it to other parts of the plant through ..

>Peptiglycons are found in the cell walls of prokaryotic cells. Proteins are polymers of aminoacids arranged in a specific sequence which is decided by the genetic code present in the DNA molecule. The polypeptide chain in a protein may be straight (primary structure) or may for..

While the nervous system and endocrine system have their own features, they have a common method of communication. Both the systems release chemicals to communicate between cells. Together these two systems carry out a very complex process of maintaining a homeostatic (balanced) internal..

>Cartilage forms the embryonic endoskeleton in most vertebrates. In sharks and rays it forms the adult endoskeleton Bone has a matrix (ossein) rich in calcium phosphate. In mammals it is deposited in the form of concentric rings called lamellae, together forming a Haversian system Fluid connective ..

All living and non-living systems are composed of molecules which follow a specific set of physical laws. The molecules found in the living systems are called biomolecules. They are represented by the molecules of about 25 elements of the 109 elements known to exist. Carbon, Hydrogen, Oxyge..

. It is seen in mammals including man. Blood is an alkaline fluid that consists of the liquid portion called plasma and the formed elements called the cells. Plasma consists of water and soluble components - proteins ( like fibrinogen), nutrients ( like glucose), metabolic substances , in..
