R.H. Whittaker gave the Five Kingdoms a classification for living organisms. He categorized living organisms according to several characteristics such as cell structure, diet, body organization, reproduction, phylogenetic relationship, etc. These five kingdoms were Monera, Protista, Fungi, Plantae and Animalia. A plant kingdom is further divided into subgroups. The classification is based on the following criteria: Let`s take a detailed look at the plant kingdom notes provided here to ensure conceptual understanding of the subject. The plant kingdom has been divided into five subgroups according to the above criteria: The plant kingdom has the following characteristics: bryophytes have no vascular tissue. The body of the plant has structures in the form of roots, stems and leaves. Bryophytes are terrestrial plants but are known as “amphibians of the plant kingdom” because they need water for sexual reproduction. They are present in damp and shady places. Bryophyta includes mosses, hornworts and liverworts.
Some of the most common examples are Marchantia, Funaria, Sphagnum, Antheoceros, etc. Let`s get to know the plant kingdom, that is, Kingdom Plantae. The plant kingdom is also divided into two groups: To learn more about the Class 11 plant kingdom, its characteristics and classification, explore the biology of BYJU.

Send us your feedback. Members of this class do not have a well-differentiated body structure, that is, the body is not clearly divided into stems, leaves and roots. A taxonomic group consisting of plants, especially terrestrial plants and green algae, is a taxonomic group that includes terrestrial plants and green algae.
In the ancient classification of organisms, according to Robert Whittaker, there are essentially five kingdoms: Animalia, Plantae, Fungi, Protista and Monera. Kingdom Plantae includes multicellular, (mainly) autotrophic eukaryotes that (usually) perform photosynthesis. Kingdom was the highest taxonomic rank or the most general taxon used in the classification of organisms. However, new classification systems, such as the one introduced by Carl Woese, include three areas. In this scheme, the domain is the most general taxon and the kingdom is only next to the hierarchy. The most recent classification scheme also placed Plantae as a sub-kingdom of the larger kingdom of Archaeplastida. Other subgroups among Kingdom Archaeplastida are red algae and glaucophytes. Members of Plantae are characterized by the following characteristics: Gymnosperms include plants that have a vascular system and a well-differentiated body structure. In addition, they carry seeds such as angiosperms, but they are not enclosed in a fruit. Hence the term “gymnosperm”, which is derived from the Greek word, gymno = nude and sperm = sperm. This is very useful and important for all students. I had the right to learn from here.
Thank you. The content is well elaborated and easy to understand, thanks to the fact that pteridophytes have a plant body well differentiated in roots, stems and leaves. They have a vascular system for the conduction of water and other substances. Some of the most common examples are Selaginella, Equisetum, Pteris, etc. Read more: Formation of seeds and fruits – seed dispersal Gymnosperms have a well-differentiated plant body and vascular tissue. They carry bare seeds, that is, the seeds are not enclosed in a fruit. Some of the most common examples of gymnosperms are cycas, pinus, ephedra, etc. Thallophyta includes plants with primitive and simple body structures.
The body of the plant is the thallus, they can be filiform, colonial, branched or unbranched. Examples are green algae, red algae and brown algae. Common examples are Volvox, Fucus, Spirogyra, Chara, Polysiphonia, Ulothrix, etc. Thallophytes: Primitive plants, where the body is not divided into stems, roots and leaves, thrive autotrophic and absorb carbon and light. Soon after, primitive life forms flourished that could absorb oxygen. Life continued to diversify, leading to the rise of various organisms competing with each other for survival. Discover these single-celled life forms that bloom on primitive soil. Angiosperms are seed-bearing vascular plants with a well-differentiated plant body. The seeds of angiosperms are enclosed in the fruits. Angiosperms are widespread and vary greatly in size, for example Wolffia is small and measures about 0.1 cm and eucalyptus trees are about 100 m tall. Angiosperms are further divided into monocots and dicots, depending on the number of cotyledons present in the seeds. Some of the most common examples are mango, rose, tomato, onion, wheat, corn, etc.
Thanks, it was useful, I will probably come back to this site later Gymnosperms: vascular plants that possess “exposed” seeds Kingdom Plantae includes all plants. They are eukaryotic, multicellular and autotrophic organisms. The plant cell contains a rigid cell wall. Plants have chloroplast and chlorophyll pigments, which are necessary for photosynthesis. Thallophytes do not have a well-differentiated body structure, and the body of the plant resembles a thallus. Angiosperms: Vascular plants that have special properties, such as flowers and fruits Phanerogame – flowering plants and seed carriers. For example Gymnosperms, Kryptogamous Angiosperms – Non-flowering and non-seed-bearing plants. Like what. Thallophyta, Bryophyta, Pteridophyta Thank you for the well-explained information more appreciation Life as we know it today probably began in the sea and many of them were probably eukaryotic organisms resembling animals.
Due to the increasing diversity of animal life forms, taxonomists eventually developed a classification system to group them into different strains. Discover the first animals, which were probably the first to roam the ancient seas, with this tutorial. Thank you mom, it was a great help to finish my project. Chlorophyll is the pigment responsible for photosynthesis in plants.
