Monocots have seeds with single seed leaf, having vascular bundles arranged in a complex manner. On the basis of the cotyledons (seed leaves) Angiosperms are further divided into Monocotyledonous plants and Dicotyledonous plants. Angiosperms also show the feature of double fertilization. The vascular system is very well developed with xylem and phloem. These plants are usually terrestrial and they may be annual, biennial or perennial. Also called the flowering plants, they are found abundantly in nature. Seeds develop inside tissues that get modified to form the fruit of the plant. Learn about Gymnosperms in more detail here AngiospermsĪngiosperms are seed-bearing plants. There is no fruit formation and the seeds are hence said to be naked. The reproductive organs generally form cones or strobilus. They have a well-developed vascular tissue but do not have vessels. The plants are usually perineal, evergreen and woody. There are about 650 living species of gymnosperm plants. They are Gymnosperms and Angiosperms Gymnosperms These plants also have a well-developed vascular system.ĭepending on whether the seeds produced are naked or whether they are enclosed, phanerogams are further classified into two subdivisions. There are well differentiated reproductive tissues that produce seeds. The plant body is well differentiated with stem, leaves, and roots. (Source: Wikipedia) Division Phanerogamae The reproductive organs in these plants are inconspicuous. These plants have naked embryos called spores. This tissue helps in the conduction of water and other substances from part of the plant to the other. The plant body is differentiated into roots, stem, and leaves, apart from having a specialized tissue for conduction. These are supposed to be the oldest vascular plants. Examples are Riccia, Funaria, and Marchantia Division Pteridophyta They live in damp and sandy habitats and are often referred to as the amphibians of the plant kingdom. But, they do not have any specialized tissue to conduct water and other substances. They show differentiation in the body design, with stem, leaf-like structures, and root-like structures.

This means that the plant body is not differentiated as roots, stem, and leaves. These are the lowermost plants of the plant kingdom, without a well-differentiated body design. The features and examples of each division are mentioned hereunder. These are autotrophic and synthesize food by photosynthesis due to the presence of chloroplasts.īased on whether plants have a well-differentiated body and the presence or absence of specialized tissues for transport, and the ability to bear seeds Kingdom Plantae (Plant Kingdom) is can be classified into different divisions. The cells have a cell wall which is made of cellulose. These living organisms are made of eukaryotic cells and are multicellular.
