Tag: why classification?

Oswald Tippo, University of Illiniois 1942, classified plant kingdom into two sub-kingdoms: Thallophyta (thalloid plant body without distinct alternation of generations) and Embryophyta (organ level differentiation of plant body with regular alternation of sporophyte and gametophyte generations). The sub-kingdom thallophyta was divided into 10 phyla: Cyanophyta (Blue green algae), Euglenophyta (Grass green algae), Chrysophyta (Yellow green algae), Chlorophyta (Green algae), Pyrrophyta (Golden brown algae), Phaeophyta (Brown algae), Rhodophyta (Red algae), Schizomycophyta (Bacteria), Myxomycophyta (Slime molds) and Eumycophyta (True fungi). Thus, the correct answer is option D. 

'Elements de Botanique' was written by Tournefort. The book aimed to define the concept of the genus for plants. It made a clear distinction between genus and species. it also helped in binomial nomenclature, where the genus name forms the first part of the binomial species name for each species within the genus.

Taxonomy is the science of classification of organisms and includes identification and nomenclature based on the description of characteristics. Taxonomy, therefore, helps to identify the unknown species. Thus, the correct answer is option A.

Linnaeus is described as the father of taxonomy due to his immense contribution in the field of nomenclature and taxonomy. He identified and classified 24 classes of flowering plants based on the number of stamens. He divided these classes into orders on the basis of carpel characteristics. This sexual, as well as artificial classification system, was first described in his book called as Systema Naturae. 

Linnaeus is considered as 'father of taxonomy'. He identified 24 classes of flowering plants based on the number of stamens and their adnate or connate state. He divided these classes into orders on the basis of carpel characteristics. Thus, option A is the correct answer.

Linnaeus is considered as the father of taxonomy. He classified the flowering plants based on the floral characters. The classification was based on the number of stamens and the basis of carpel characteristics. Since, his classification employed sexual characters, it is termed as sexual classification. The artificial system of classification is based on the observable characters such as habit, number, forms, the number of stamen which makes the classification system proposed by Linnaeus as an artificial system.

Theophrastus is considered father of botany. He was the Greek philosopher and the first to attempt to classify plants on the basis of their morphological features. On the basis of their height, girth and branches, the plants were classified as tree, shrubs, sub-shrubs and herbs.

Theophrastus is considered father of botany. He was the Greek philosopher and the first to attempt to classify plants of the basis of their morphological features. On the basis of their height, girth and branches, the plants were classified as tree, shrubs, sub-shrubs and herbs. He considered the trees as most advanced plant and classified around 500 plant species of plants which are mentioned in his book Historia Plantarum. Enquiry into Plants and On the Causes of Plants were also penned by him.
