Summary - In lower organisms, there is no transport system as the cells are in touch with the surrounding medium. The transport is by the physical processes like diffusion, osmosis, etc. With the advancement in structure, the organisms have to evolve methods to transport nutrients and was..

Summary - 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. Regenerat..

Summary - Study of the compounds of carbon is organic chemistry. They form the basis of living organisms and the things around us. An unique property of carbon is 'catenation'. It is the property of forming bonds with the atoms of the same element. The catenation property of carbon is the..

Summary - The macromolecules found in a cell are large molecules with a complex structure and very high molecular weight. They are represented by polysaccharides, proteins and nucleic acids. Polysaccharides are polymers of monosaccharides. They are linear, branched or unbranched molecular..

Summary - Endocrine system consists of many endocrine or ductless glands, which secrete hormones into the blood. Hormones are information molecules, which regulate specific physiological processes in the target cell, tissues or organs. Hormones co-ordinate the activities of different orga..

Summary - Smallest unit of ecological hierarchy is the organism, while smallest and basic unit of taxonomic hierarchy is species. A group of individuals, having similar structural and functional characters, capable of potential interbreeding is termed as species. In nature all a..

Summary - Let y = f(x) be a smooth curve and P(x,y) be a point on the curve. Equation of the tangent at (x 1 , y 1 ) in the curve y = f (x) is y - y..

Summary - While the nervous system and endocrine system have their own features, they have a common method of communication. Both the systems release chemicals to communicate between cells. Together these two systems carry out a very complex process of maintaining a homeostatic (balanced)..

Summary - Alcohols and Phenols are compounds containing -OH as the functional groups. In alcohols, the -OH group is attached to sp 3 hybridised carbon. In phenols, it is attached to sp 2 hybridised carbon of an aromatic ring. In ethers, oxygen atom is attached to two carbons ato..

Summary - All higher multicellular animals, called eumetazoans, exhibit a tissue and higher levels of organization There are four primary tissues in animals epithelial, muscular, connective and nervous Epithelial tissue (epithelium) is the simplest. It is avascular and develops from all t..
