plant genus and species

Both genus and community are formed of many species. But the two differ from each other in some basic characters. Species in a genus have a common ancestry. They occur in different geographical regions and often have no functional relation or interaction amo..

Several disease, pest and drought resistant varieties of wheat, tomato, sugarcane have been evolved by this metho..

Intentional or chance introduction of exotic species into new islands or countries by man adversely affects the native species. Example: Rabbits and goats introduced in Pacific and Indian ocean islands are destroying the habitats of many native plants, reptiles and bi..

Many years ago, Frederick Steward and his co-workers cultured cells from carrot plants and induced some of them to develop into small embryos. Some of these embryos grew into whole plants. Today, researchers routinely regenerate crops, plants and many other ..

Need for Preservation - Plants and animals occupy diverse habitats. It becomes practically impossible for a biologist to study each and every plant or animal species in its natural habitat. Hence, over the years attempts have been made to preserve the plant h..

The creation of a life form, by a similar life is called reproduction. Reproduction is the extension of life of a species at a given time. It is a means of perpetuation of the species and also multiplies their number. By this process, the individuals transmit life to the n..

In the description of Angiosperms, family is the most useful taxonomic unit. Ranks higher than family are not of much practical significance and are used mostly in classification systems and academic discussions. The taxonomic category genus also does not get much importance as ..
