structural organisation in animal and plant

Animal Organisation - 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, symmetr..

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 achiev..

Ecosystem - Structure and Function - The characteristic structure of an ecosystem is obtained by the systematic physical organisation of the abiotic and biotic components of that particular ecosystem. The two main structural features of any ecosystem are its ..

Respiratory System in Human Beings The respiratory system starts with the nose that encloses the nasal cavity. The nasal cavity opens to the outside through the openings called the nostrils. The nasal cavity is divided into two portions by a cartilagenous septum and is lined by fine hairs that..

Plants and animals occupy diverse habitats. It becomes practically impossible for a biologist to study each and every plant or animal species in its natural habitat. Hence, over the years attempts have been made to preserve the plant species o..

Differences between plants and animals - Plants Animals Cellulose cell wall surrounds the cell membrane Cell wall is absent in animal cells Plastids are present-especially a green pigment called chlorophyll. Chlorophyll is absent in animal..

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..
