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 nu..

The Animal Kingdom is divided in several phyla mainly on the basis of the cell organisation, symmetry, presence or absence of notochord and body cavity. Animals are arranged progressively from simple single-celled protozoans to highly complex mammal..

: In this group cells do not form tissues. Hence, animals have remained at the acellular grade or organisation. For example, Sponges..

Living organisms have a definite organisation consisting of structural and functional units called cells that make the physical basis of life namely protoplas..

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..

Every multicelluar organism begins its life as a single cell called zygote which by cleavage forms numerous identical cells. As development proceeds, these cells become specialised into components of various tissues and organs. The process of specialisation cal..

All living organisms are composed of one or more cells. A cell is the structural and functional unit of life. The metabolic reactions in a living organism - can occur only in a delicately balanced environment. Through their unique chemical composition, cells..
