Photosynthesis is the only process which produces enormous quantities of organic matter for sustaining the life on this globe. It is the only known method of manufacture of organic food from inorganic raw materials. Animals including man are directly or indirectly dependent on photosynthetic plants..

Some bacteria are known to fix the atmospheric nitrogen for their own biological activity. This natural phenomena is commercially utilized to increase the nutrient supply to crops. There are two types of nitrogen fixing bacteria. They are a) Symbiotic N 2 fixing bacteria - well known exam..

Study of photosynthesis and the factors affecting it helps us understand the most important biochemical life sustaining processes. All plants and animals are dependent on the sun for energy. This energy is made available to them by the process of photosynthesis. Man, like other animals, is depende..

1. To understand molecular events in biological processes such as cell differentiation and aging. 2. It can be used to make precise gene maps. 3. Useful chemical compounds can be produced example: injectable hepatitis B vaccine. 4. It has provided a broad range of tools to aid physicians ..

Many synthetic auxins have been developed because they are found useful in many ways. These synthetic auxins are cheaper to develop than the natural auxins. They are also more effective as the plants are not able to degrade them easily. Some of the uses of synthetic auxins are given below: Fruiti..

They are used in tissue culture to induce cell division in mature tissues. They also induce development of shoot and roots along with auxin, depending on the ratio. They are used to delay senescence in fresh leaf crops like cabbage and lettuce. They are used to keep flowers fresh..

It is used as a spray on trees to regulate dropping of fruit..

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 form the ..

Each of the derived parameter in the study of population has specific significance. Some important parameters is given bel..
