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.

Plant Taxonomy: History, Classification and 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 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.

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.

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.

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.

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.

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.

Non flowering plants are included under (1) cryptogamae (2) phanerogamae (3) angiosperms (4) Both a and b.

Classification of Organisms: The major area or basis of classification are. Mode of nutrition. Level of organization. Plant kingdom was divided in two sub kingdoms by Eichler. Two kingdom system: This system of classification is the oldest. It was proposed by Carolus Linnaeus in 1758.

The modern system of classification of living organisms was proposed by R.H. Whittakar in 1969 in which all living organisms have been classified into five kingdoms viz. Monera (all prokaryotes), Protista (unicellular eukaryotes), Plantae ( multicellular and chlorophyllous eukaryotes), Fungi (multicellular and non-chlorophyllous eukaryotes) and Animalia ( multicellular and ingestive eukaryotes).
