role of mitochondria in cells

Mitochondria are tiny structures that occur in varying shapes cylindrical, spherical, oval, rod shaped etc. They are found distributed all over the cytoplasm. fig. 16.6 - Mitochondria Each mitochondrion is bound by a double membrane. The outer membrane is smooth and straight, wh..

These may be cylindrical, rod-shaped or spherical and distributed in the cytoplasm. Each mitochondrion is bound by a double membrane. The inner membrane is folded into ridges called cristae, which increase the surface area of the membrane...

Hormones are informational molecules. They are secreted in response to changes in the environment inside or outside the body. These are released into the extracellular fluid, where they are diffused into the blood stream. The latter carries them from the site of production to the site of action. Th..

The leucocytes are phagocytic and engulf the bacteria and other micro-organisms that attack the body cells. The lymphocytes secrete antibodies, that are special protein molecules that act against specific proteins present on the surface of the germs. These proteins are called the antigen..

The liver is a multipurpose,largest gland in vertebrates. It plays a vital role in excretion of many substances. (a) Liver changes the decomposed haemoglobin of the worn out red blood corpuscles into bile pigments bilirubin and biliverdin. These pigments are passed into the alimentary can..

Each cell can be regarded as a compartment by itself since it is bound on all the sides by a cell membrane. It separates the protoplasm within the cell from the surrounding environment. As a result, the cell is able to retain specific molecules and carry out ..
