They are located in cytoplasm.




They are round or oval in shape.




The number of mitochondria depends upon the function of organisms.




  1. i) Outer membrane of mitochondria is smooth.


  1. ii) Inner membrane is greatly folded in the mitochondrial materials.


iii) They are small rounded particles called cristae




They are called power house of the cell. They contain respiratory enzymes which oxides the food and release energy. This energy is used to perform different activities of life.


Note: Depending on the university and specialty chosen, the materials may also include audio lectures, interactive tutorials, video lectures. It should also be borne in mind that no type of technology, including education via the Internet, will not force the development of an irrepressible willpower, strong character, assiduity, necessary for the effective mastery of scientific spaces. If these qualities are not available, and you know about it, then it makes sense to consider the option of admission to the full-time form of training. A distance learning student is a part-time student, and may be able to listen to so-called installation lectures every semester, as happens at the Faculty of Economics of the St. Petersburg Technological Institute. The main thing is to set a goal and do everything possible to achieve it. In this case, any training, both daytime, and distant, and independent, can stun by its results.
