What was Eichler classification of kingdom plantae?
Eichler classified the plant kingdom into two sub-kingdoms. They are Cryptogamae and Phanerogamae. The cryptogams are flowerless and seedless plants. They are simple plants like algae, mosses and ferns which do not produce flowers, fruits and seeds.
On what basis does Eichler classified plants?
On the basis of presence or absence of flowers and seeds, Eichler classified plant kingdom into two sub-kingdoms namely Cryptogamae (absence of flowers and seed; reproduction by spores) and Phanerogamae (presence of flowers and seeds).

What are examples of Thallophyta?
Examples of Division Thallophyta: Green algae – Ulothryx, Cladophora, Spirogyra, Ulva, and Chara; Red algae – Batra, Polysiphonia; Brown algae – Laminaria, Fucus, Sargassum.
What is the difference between cryptogams and Phanerogams?
The main difference between cryptogams and phanerogams is that Cryptogams consist of seedless plants whereas phanerogams consist of seed-bearing plants. Cryptogams comprise plants like algae, mosses, and ferns. Phanerogams comprise gymnosperms and angiosperms.
Are Pteridophytes cryptogams or Phanerogams?
Pteridophytes are also called as Vascular Cryptogams because they produce neither flowers nor seeds and also because of the conduction tissues which are called as vascular bundles. Pteridophytes are said to be non-seed bearing plants which reproduce only by production of spores.
Who gave phylogenetic classification?
John Hutchinson was a British botanist associated with Royal Botanic Gardens, Kew, England. He developed and proposed his system based on Bentham and Hooker and also on Bessey. His phylogenetic system first appeared as “The Families of Flowering Plants” in two volumes.
Why is Thallophyta called Thalloid plant?
Thallophytes (Thallophyta or Thallobionta) are a polyphyletic group of non-mobile organisms traditionally described as “thalloid plants”, “relatively simple plants” or “lower plants”. They are simple plants without roots stems or leaves. They are non-embryophyta. These plants grow mainly in water.
Is bacteria Thallophyta?
Thallophyta A former division of the plant kingdom containing relatively simple plants, i.e. those with no leaves, stems, or roots. It included the algae, bacteria, fungi, and lichens.
What are the three major group of cryptogams?
The best-known groups of cryptogams are algae, lichens, mosses and ferns, but it also includes non-photosynthetic organisms traditionally classified as plants, such as fungi, slime molds, and bacteria.
What are cryptogams Why are they so called?
In the plant kingdom, non-flowering plants or non-seed generating plants or spore producing plants are named as Cryptogams. Cryptogams are algae, bryophytes and pteridophytes. They are classified as cryptogams, because it is difficult to see their reproductive organs.
Is Thallophyta vascular?
Thallophyta: Thallophyta lacks a vascular system.
Are gymnosperms cryptogams?
Thallophyta, bryophyta and pteridophyta are called as cryptogams, gymnosperms and angiosperms are called as phanerogams. Thallophyta, Bryophyta, and pteridophyta are called cryptogams because the reproductive organs of these groups are inconspicious or hidden. Seeds are absent.
What does Eichler mean?
A user from Minnesota, U.S. says the name Eichler is of German origin and means “Dweller by the oak”.
What is Eichler style home?
Eichler homes are examples of Modernist architecture that has come to be known as “California Modern”, and typically feature glass walls, post-and-beam construction, and open floorplans in a style indebted to Frank Lloyd Wright and Mies van der Rohe.
Who proposed the first phylogenetic system?
August W. Eichler
The Eichler system was the first phylogenetic system developed by August W. Eichler. Hence the correct answer is Eichler. Note: Plants that have flowers make up the largest group of Plantae Kingdom.
Who proposed natural system of classification?
Bentham and Hooker proposed the natural system of classification of seed plants in three volumes of “Genera Plantarum”.
Is Dictyota Thallophyta?
They show great variation in size and form. They range from simple branched, filamentous forms (Ectocarpus) to profusely branched forms as represented by kelps, which may reach a height of 100 metres. The common forms are Ectocarpus, Dictyota, Laminaria, Sargassum and Fucus.
