Species is a collection of individual plants which resemble one another in almost all important morphological characters- both vegetative and reproductive- so closely that they may be regarded as having been derived from the same parents. Such as all pea plants constitute a species.
Occasionally due to variation in climatic or edaphic conditions, individuals of a species may show certain amount of variation in form, size, colour and other minor characteristics. Such plants are said to form varieties.
A genus is a collection of species which bear a close resemblance to one another in the morphological characters of the floral or reproductive parts but differ from one another in their vegetative characters. Such as Banyan, Peepul and Fig are under the genus Ficus.
