The CC- Botany 1 entitled Plant Groups is actually a course on basic plant diversity and comprises of 40 modules. It gives a detailed account of different plant groups like virus, bacteria, algae, fungi including and mycorrhizae, archegoniates including bryophytes, pteridophytes and also the spermatophyte in the form gymnosperms. Each group have detailed discussion of their classification, ecological importance, classification and phylogeny, certain important type genera and also their economic importance. Thus by studying these 40 modules, a student should be able to understand and appreciate the major plant groups from microbes to gymnosperms which form the basis of plant sciences. Students from any branch of biological sciences will find these modules relevant and useful for their higher studies.
