types of structures whithin the structural organisation level

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 ..

The molecules of various chemical substances in a specific proportion become organised into protoplasm - the physical basis of life. The protoplasm gets organised into cells, which represents the structural and functional unit of life. A living organism may have a sin..

The floating gas holder type of biogas plant has the following chambers/ sections: Mixing Tank - present above the ground level. Digester tank - Deep underground well-like structure. It is divided into two chambers by a partition wall in between. It has two long..

A cell is regarded as the structural and functional unit of life. Thus a living organism must consist of at least one cell. Cells combine to form higher units, the tissues, which in turn come together and constitute the next higher unit, known as the organs. The organs occur in groups, to..

Every organism consists of parts that can be arranged in increasing levels of complexity. Each higher level is more complex than the one below it. The smallest structural unit of matter, both non-living and living are protons, neutrons and electrons. These particles co..

At the molecular level all the different types of cells in living organisms are composed of certain chemical substances. The structure and function of the cell and its components are dependent on the molecular structure, arrangement and properties of th..

There are two basic types of cells found in living organisms - the prokaryotic cells and the eukaryotic cells. This classification is based on three main features, namely; Organisation of biomembranes Nature of cytoplasmic organelles and Arrangement of the nuclear material The p..

Growth is an irreversible increase in size and weight of an organism. The cells of the body do not grow uniformly but differentially. The main types of growth are auxetic, multiplicative and accretionary. The human growth curve is sigmoid and is controlled by hormones. Regeneration is of ..
