application of colloids in biology

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..

Dormancy of seeds can be broken by auxin application..

Introduction - The different kinds of micromolecules and macromolecules that we have studied so far occur in the cell dissolved in solution or as suspensions in a colloidal state. Alternatively, they may be assembled into subcellular components like cell membrane, cytoplasm and cell organ..
