level of organisation in plant and animal

Animals exhibit a complex body organisation which shows a very clear evolutionary trend. The complexity of animal organisation is seen with reference to features like cellularity, germ layers in the body wall, symmetry of the body parts and the nature of body..

Living Beings are Organised - Organisation refers to a kind of structure or system or situation where the smaller components become arranged into larger ones in a hierarchical order of complexity, to co-ordinate with one another in performing common functions or achieving common..

Summary - Plants and animals occupy diverse habitats. It may not be possible to study most of them in their natural habitat. Attempts have been made to preserve the plants and animals in a form suitable for scientific studies. Such attempts have resulted in t..
