Classification of Plant Groups- Cryptogamae and Phanerogamae In 1883, A.W. Eichler gave a system of classification for the whole plant kingdom. it is a traditional system as well as a phylogenetic system of classification of plants. Eichler classified the plant kingdom into two sub-kingdoms. They are Cryptogamae and Phanerogamae.
Cryptogams are classified as lower plants because they don't have many of the structures we associate with plants. In part, this is because most cryptogams aren't even in the plant kingdom.
Answers: Based on the system of classification proposed by A. W. Eichler (1875 -78), the plant kingdom is divided into two subkingdoms Cryptogamae and Phanerogamae. The cryptogams are flowerless (non-flowering) and seedless, spore-bearing plants. Phanerogams are flower bearing, seed producing tracheophytes. Q4.Classification of plants is based on morphology, presence and absence of vascular tissue and presence and absence of seeds, flower and fruits. In 1883, Etcher modified the classification of kingdom Plantae by adding two sub kingdoms, Cryptogams and Phanerogams. Plant Kingdom - definition.A plant that has no true flowers or seeds, including ferns, mosses, liverworts, lichens, algae, and fungi. A cryptogame (scientific name Cryptogamae) is a plant (in the wide sense of the word) that reproduces by spores, without flowers or seeds.. This included all plants with concealed reproductive organs.
The Perfectae were subdivided into Dicotyledonae and Monocotyledonae and under Dicotyledonae he placed 25 of his classes and 4 under Monocotyledonae. His system of classification came out in his “Historia plantarum” of which several editions were published and he revised and improved his system in the later editions.Read More
The Eichler System divided the plant kingdom into non-floral plants (Cryptogamae) and floral plants (Phanerogamae). It was the first to accept the concept of evolution and therefore also the first to be considered phylogenetic.Moreover, Eichler was the first taxonomist to separate the Phanerogamae into Angiosperms and Gymnosperms and the former into Monocotyledonae and Dicotyledonae.Read More
In five kingdom classification, all plants except fungi and some algae have been put in kingdom plantae; Classification of plant kingdom A.W Eichler in 1883 classified entire plant kingdom, both traditional and a phylogenetic based classification, Divided Plant Kingdom into Sub kingdom Cryptogamae and Phanerogamae Cryptogamae (Greek.Read More
Many biologists subscribe to a Six Kingdom system of high-level classification. The following Table lists the groups commonly regarded as cryptogams (underlined) by Kingdom, along with some of the other organisms (that aren't dealt with at this site) that are classified in these Kingdoms. Keep in mind, many intelligent people disagree about how.Read More
R.H. Whittaker proposed the five kingdom classification in 1969. This classification was based upon certain characters like mode of nutrition, thallus organization, cell structure, phylogenetic relationships and reproduction. This form of kingdom classification includes five kingdoms Monera, Protista, Fungi, Plantae and Animalia.Read More
Eichier’s System of Classification: In 1883, a system of classifying the flowering plants was proposed by A.W. Eichler (1839- 1887) is also remarkable because of its resemblance with widely accepted Englerian system. An outline of Eichier’s system is given below: A. Cryptogamae: B. Phanerogamae: 1. Gymnospermae: 2. Angiospermae: 1.Read More
The classification of living things based on shared characteristics is called Taxonomy. Taxonomy is the science dealing with the description, identification, naming, and classification of organisms. The modern taxonomic system was developed by a Swedish botanist Carolus Linneaeus (1707-1788) who provided scientists and students a way to sort and group organisms for easier study.Read More
