Summary - All multicellular animals are now placed in the kingdom of Metazoa. The multicellular animals show a very specific body organisation which ranges from cellular grade to organ system grade. Higher in the hierarchy of animal kingdom, one can recognise appearanc..

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., the aphid. In many social insects, such as th..

The environment in which the man and other organisms live is called the biosphere. The biosphere is made up of different regions that have different types of flora (plants) and fauna (animals). The types of organisms in an area are determined by various factors such as the climate, tempe..

It consists of a pair of lungs, a pair of bronchi and a trachea. The lungs contain numerous microscopic functional units called alveoli. These structures are involved in pulmonary respiration. In addition, there is buccal respiration, through the buccal cavity and cutaneous respiration th..

It is represented by a pair of kidneys, a pair of ureters and a urinary bladder. Kidney contain numerous units called nephrons which filter blood, remove urea and convert it into urine. It is collected in the urinary bladder through ureters (kidney ducts), temporarily stored and then peri..

Cardiac Muscle - It is also known as heart muscle. The cardiac muscle fibres do not form fasciles. They are arranged in the form of a network. The muscle fibres are elongated, cylindrical and branched. The branches become inter-connected with one another to form a network. The space between the mus..
