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. Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom.

A plant kingdom is further classified into subgroups. Classification is based on the following criteria: 1. Plant body: Presence or absence of a well-differentiated plant body. E.g. Root, Stem and Leaves. 2. Vascular system: Presence or absence of a vascular system for the transportation of water and other substances. E.g. Phloem and Xylem. 3. Seed...
Thallophytes lack a well-differentiated body structure and the plant body is thallus like. Thallophyta includes plants with primitive and simple body structures. The plant body is thallus, they may be filamentous, colonial, branched or unbranched. Examples include green algae, red algae and brown algae. Common examples are Volvox, Fucus, Spirogyra,...
Bryophytes do not have vascular tissues. The plant body has root-like, stem-like and leaf-like structures. Bryophytes are terrestrial plants but are known as “amphibians of the plant kingdom” as they require water for sexual reproduction. They are present in moist and shady places. Bryophyta includes mosses, hornworts and liverworts. Some of the co...
Pteridophytes have a well-differentiated plant body into root, stem and leaves. They have a vascular system for the conduction of water and other substances. Some of the common examples are Selaginella, Equisetum, Pteris, etc. More Details: Pteridophyta
Gymnosperms have a well-differentiated plant body and vascular tissues. They bear naked seeds, i.e. seeds are not enclosed within a fruit. Some of the common examples of gymnosperms are Cycas, Pinus, Ephedra, etc.
Angiosperms are seed-bearing vascular plants with a well-differentiated plant body. The seeds of angiosperms are enclosed within the fruits. Angiosperms are widely distributed and vary greatly in size, e.g. Wolffia is small measuring about 0.1 cm and Eucalyptus trees are around 100 m tall. Angiosperms are further divided into monocotyledons and dic...
Plant - Photosynthesis, Reproduction, Evolution: Plants (kingdom Plantae) are all multicellular and eukaryotic, and most can convert the energy of sunlight into chemical energy by means of photosynthesis; they are autotrophic and store their excess food as starch. Nonvascular plants (bryophytes) lack specialized vascular tissue for internal water and food conduction and support; they do not ...
Apr 28, 2017 · Plant Definition. Plants are multicellular organisms in the kingdom Plantae that use photosynthesis to make their own food. There are over 300,000 species of plants; common examples of plants include grasses, trees, and shrubs. Plants have an important role in the world’s ecosystems.
Apr 9, 2020 · A plant is a living organism in the kingdom Plantae. Plantae is one of the five (or six, depending on which system is being used) kingdoms into which all living things are categorized. Other kingdoms include Animalia (the animal kingdom) and Fungi (fungi aren’t plants).
