angiosperms class

. Each stamen has an anther and a filament. The anther produces pollen grains containing the highly reduced male gametophyte . The carpels represent megasporophyll. They enclose ovules containing the egg cell which with the associated cells represent the female gametophyte . A characteristic featur..

Angiosperms represent the most advanced group of vascular plants. They are commonly called 'Flowering plants'. They exceed all other major groups of living plants in number and diversit..

Introduction - There have been several attempts to classify angiosperms, the flowering plants. One of the earliest attempts in this direction was that of Carolus Linnaeus. He attempted a classification of angiosperms based on the characteristics related to flowers. Subsequent ta..

Introduction - Angiosperms are a group of flowering plants that represent a major community in the plant kingdom. Angiosperms occur in all typical habits and constitute a very useful group of plants for animals and human beings. They include about 2,50,000 species distributed al..

Introduction - 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 importanc..

Angiosperms exhibit a great diversity in form, size, structure and life span of the plant body. Based on the duration of life span, angiosperms are classified into annuals, biennials and perennia..

The natural systems of classification of angiosperms have mainly used the floral characteristics as the basis. Some of the earlier attempts in this direction were those of Linnaeus, John Ray, Bentham and Hooker. However, these systems of classification are now termed as non-phylogen..
