(b) A is incorrect but R is correct. Algae are generally classified on the basis of the following characteristics:  Chemical and physical feature of the cell walls  Nature and properties of pigments that contribute to photosynthesis  Morphological charactersitics of cells and thalli. It was published in the Journal of Phycology this week. [Article in Russian] Gromov BV, Avilov IA, Skrupskaia VA. PMID: 5877292 [PubMed - indexed for MEDLINE] MeSH Terms.

The main phylogenetic groups of algae are. Ways to define an animal species have been established by scientists, such as determining the ability of an organism to produce viable offspring which can reproduce in the future.

CLASSIFICATION OF ALGAE. F.E. Log in. All protozoal species are assigned to the kingdom Protista in the Whittaker classification.The protozoa are then placed into various groups primarily on the basis of how they move. • Phaeophyceae: Chlorophyll a and c and fuxoxanthin are present. Reproduction. Examples are Chlamydomonas, Spirogyra, and Chara. The classification of bacteria serves a variety of different functions. • Chlorophyceae: Chlorophyll a and b are present in them and impart green colour. In several chrysophytes the cell walls square measure composed of polyose with massive quantities of silicon dioxide. Fritsch (1935, 1945) in his book “The Structure and Reproduction of the Algae” proposed a system of classification of algae. In the present work we simply classify algae depending on their … Algae also form a component of periphyton, which not only provides New rules for classification of algae species. So, the perception of biodiversity and conservation changes depending on how a species is defined, said McCoy. This video is unavailable. Classification of Fritsch was based on the following criteria Pigmentation Types of flagella Assimilatory products Thallus structure Method of reproduction Fritsch divided algae into the following 11 classes 1.Chlorophyceae 2.

Babcock (1974) suggested that paleontologic criteria for algal classifications should be restricted to preservable diagnostic criteria used in the identification of living algae, and, in addition, should exclude dimensional variability as a basis for establishing minor taxa. Criteria for algae classification may vary from scientist to scientist, as some might categorize offsprings of two algae species as a distinct species while others might not do so. Flagellar arrangement 4. But similar categorization does not work for algae. Criteria for the classification of blue-green algae (cyanobacteria) at the genus and at the species level Hoffmann, Lucien Algological Studies/Archiv für Hydrobiologie, Supplement Volumes No. Division-level classification, as with kingdom-level classification, is tenuous for algae. Watch Queue Queue. The groups are called phyla (singular, phylum) by some microbiologists, and classes by others. Classification of Algae. Their photosynthetic pigments are more varied than those of plants, and their cells have features not found among plants … Some might consider discrete DNA for classification while others might consider the physical characteristics of the organism. This helps to distinguish a horse and a donkey as two separate species. Log in. 87 success. A universal set of rules is missing when it comes to the classification of algae. Which of the following would most likely happen if the ATP synthesis in the mitochondria of a pla Members of the four major groups are illustrated in Figure 1 . 25, Nº. The term algae (or seaweeds) is a practical term to use in everyday language, even if it has lost all clear meaning in the new phylogenetic classification of living organisms! He treated algae giving rank of division and divided it into 11 classes. Algae has its own unique and complex stages of the lifecycle and very often they interbreed with algae from other species. Pigmentation and Photosynthetic apparatus 2. If answered seriously i will make brainlest. Usually a number of characters are employed altogether ranging from the external morphology, ultra structure, chromosome number and their morphology, nature of cellular storage products, pigment composition, enzymes, DNA homology & DNA banding and so on. Criteria for Classification and Labelling of Substances and Mixtures 17 June 2009. The protozoa are then placed into various groups primarily on the basis of how they move. Apart from conservation, catastrophes – from the destruction of coral reefs to algal blooms in waterways, all could be extenuated by discussing and specifying the classification of algae. His classification was based on such criteria as pigmentation, types of flagella, assimilatory products, thallus structure and methods of reproduction. classification of algae was given by F.E Fritsch (1935) in his book ‘The Structure and Reproduction of the Algae’. Chlorophyll a and chlorophyll b; Green; Phaeophyceae. Criteria for algae classification may vary from scientist to scientist, as some might categorize offsprings of two algae species as a distinct species while others might not do so. [Article in Russian] Gromov BV, Avilov IA, Skrupskaia VA. PMID: 5877292 [PubMed - indexed for MEDLINE] MeSH Terms. Criteria for classification of Algae: The criteria employed by phycologists are quite diverse. Most diatoms exist on an individual basis, though some are part of to make colonies. •The current systems of classification of algae are based on the following main criteria: o kinds of photosynthetic pigments, o type or chemical nature of photosynthetic energy storage products o photosynthetic membranes’ (thylakoids) organization and other features of the chloroplasts. She further added to it that the number of species could go way up or way down depending on how the rules are applied. Join now. A universal set of rules is missing when it comes to the classification of algae. While green and red algae are considered plants (kingdom Plantae), brown algae belong to a different kingdom called Chromista (Cavalier-Smith, 2007 ). Eukaryota/classification* Criteria for classification of Algae: The criteria employed by phycologists are quite diverse. However, the differences in their ecology, such as what they look like or their role in the environment should also be taken into account. Cryptophyceae 6. Presence of pigments which imparts traditional color on algae is the main basis for the classification of algae. Pigmentation 2. Botany Classification of Algae And Characteristic Features of Algal Groups Question Answers Index for BSc 1st Year Botany Classification of Algae Sample Model Practice Question Answer Papers.
