The most common retention parameters used in the planer chromatography.list the examples of such techniques.
Answers
Answer:
Thin layer chromatography (TLC), or planar chromatography, began as a method of separating mixtures by eluting them through a planar chromatographic bed then visualising the separated components by staining or charring. In its simplest form TLC plates can be prepared in the laboratory, the plate placed in any suitably sized container and the resultant chromato-gram scanned visually. At its most sophisticated there is a large variety of plates, sample application aids including automated applicators, developing chambers, visualisation aids, scanning devices and adsorbents commercially available. TLC can be an excellent qualitative and quantitative method and more detailed descriptions of the techniques employed will follow.
Answer:
Plants do not eat food that is provided by someone else; they make their own food by the photosynthesis process. If you understand what photosynthesis is, you will be able to know a lot about the cellular and chemical activities taking place in plant bodies..
The word photosynthesis comes from two Greek words, fos (light), and synthesis (combining). The photosynthesis definition says that it is a combination of plant food's creation with the help of light.
Photosynthesis reaction occurs in green plants, and in some prokaryotes, purple bacteria, and green sulfur bacteria. The photosynthesis process in all of them is similar.
In plants and blue-green algae, the photosynthesis process takes place in chloroplasts. The chloroplast is present in all green parts of a plant – the leaves, green stems, sepals, and even in the flowers, in the form of green colour plastids. The chloroplast is found only in plant cells and is essential for photosynthesis reaction
