Gymnosperms and Angiosperms under Plantae . Let us also look at classification within angiosperms to understand some of the concerns that influenced the classification systems. The earliest systems of classification used only gross superficial morphological characters such as habit, colour, number and shape of leaves, etc. They

Introduction. The kingdom Plantae constitutes large and varied groups of organisms. All are eukaryotic, multicellular with differentiated tissues, and photosynthetic. There are more than 300,000 species of cataloged plants. Of these, more than 260,000 are seed plants.
classification within Kingdom Plantae popularly known as the ‘plant kingdom’. We must stress here that our understanding of the plant kingdom has changed over time. Fungi, and members of the Monera and Protista having cell walls have now been excluded from Plantae though earlier classifications placed them in the same kingdom. So, the ...

Plantae are classified as follows : Kingdom Plantae (Embryophyta) is classified into the following divisions: 1. Bryophyta : Amphibians of plant kingdom, non-vascular. 2. Pteridophyta : True root, stem and leaves, vascular tissue present. 3. Spermatophyta : Seed producing, vascular tissues present. Spermatophyta are further divided into:
Introduction to Kingdom Plantae Fundamental Features 1. Most of the plants are eukaryotic and chlorophyll containing organisms. Cell walls of plant cells are comprised of cellulose. 2. They have an ability to grow by cell division. 3. In life cycle of plant cells, the interchanges occur from the embryos and are supported by other tissues and ...
