histological classification of animal tissues

Meristematic Tissue (Meristem) - The meristematic tissue is formed exclusively by undifferentiated or embryonic cells. These cells, known as meristematic cells, are responsible for bringing about growth of the plant body due to their capacity to undergo continuous mitotic divisi..

) which is activated to grow into separate organism by suitable mixture of cytokinins and auxins. The success in tissue culture depends upon a) the precision and length of asceptic condition b) source of explants c) compositions and concentrations of nutrients media d) time and dosage of ..

Parthenogenesis and Tissue Culture - Parthenogenesis is a form of reproduction in which the ovum develops into a new individual without fertilisation. Natural parthenogenesis has been observed in many lower animals (it is characteristic of the rotifers), especially insects, e.g...

Introduction - All living creatures need food. The food is consumed so that energy is obtained. The energy is utilised by the body for various purposes like locomotion, conduction of impulses, repair of damaged tissues, building of cell materials, et..

Scrape the inside of your cheek using an ice-cream spoon. Spread the tissue in a drop of water on a glass slide. Add a drop of methylene blue and place a cover slip. Observe the cells (epithelial) under the microscope. Epithelial cel..

The permanent tissues are formed by the differentiated cells, which become specialised to perform specific functions like protection, support, storage and conduction. The permanent tissues always differentiate from the meristematic cells, during the process of grow..

A cell, a tissue or an organ, which secretes certain useful chemical compounds required for a particular function, is called a Glan..

Introduction - The nitrogenous waste materials produced in the animal body due to metabolic reactions are of no use to the cell. These waste materials if allowed to accumulate in the body, may become toxic. Therefore, they must be removed from the body. The process of elimination of metab..
