Economical importance of bryophytes

-
ECOLOGICAL IMPORTANCE OF BRYOPHYTES Mosses and Bryophytes are the first organiasms to colonise rocks. They colonise rock by acidic secretion. This acidic secretion is due to the death of mosses. When the rock is decomposed it helps in soil formation. Therefore New soils are formed. The soil act as binders.  It prevent soil erosion. The water retention capacity of the soil is high ie, water holding capacity of the soil is high.  This reduces surface water run-off which prevent soil erosion. Bryophyte helps in the recycling of nutrients. ECONOMICAL IMPORTANCE OF BRYOPHYTES. 1) SPHAGNUM Sphagnum has high absorptive power with antiseptic property. This can be used to replace cotton in bandages. 2) MERCHANTIA   Mercahntia cures pulmonary tuberculosisand affliction (pain) in liver. Antibiotic substances are also extracted from bryophytes. it also acts as antiseptic, and as preservative POLYTRICHUM Polytrichum dissolove stone in kidney and in gall bladder. 3) IN RESEARCH It is used in the fie

Basics of biological classification-to living world- part 1

Basics of biological classification  
    Systematics- ( Latin word systema - order or sequence) it is the study of diversity of organisms and all their comparative and evolutionary relationship based on comparative anatomy, physiology, biochemistry and ecology. 

  Classification- it deals with the study of ordering of organisms into groups. 

   Taxonomy- it is the study of naming , defining and Clalassifying groups of biological organisms based on their characters. . 

   The term systematics coined by C. Linnaeus. Generally the such as systematics, classification, and taxonomy are used interchangeable but taxonomist like  Simpson relate them to Separate fields. He regarded as the classification is the subtopic of systematics and taxonomy is the study of principles and procedures of classification. 

   Cladistics- it classify to organisms according to the historic order in which the evolutionary branches arose. It led to the emergence of new systematics or biosystematics. ( it's a concept of systematics that consider a species to be a product of evolution). 

Baaics in classification
i. Characterization and identification
ii. Nomenclature
iii. Classification

   To classify an unknown organism by comparing it with known organisms, it's done with the help of taxonomical aids. 

  Keys- a scheme for identification of plants and animals. Also refers to the set of alternate characters arranged in such a manner that helps in the identification of an organisms by selecting or eliminating the characters according to the presence or absence in the organism. This is carried out for an organisms by determining its similarities With a already known species. So, these are more useful in the identification of unknown organisms. 

Taxonomical aids( mother or help) 
     Both the laboratory and field studies are important for identification of various species, Thu s the information gathered  about the species need to be stored for future studies. The actual specimen are collected, preserve, and stored for verification if required later on. These are various techniques and procedures and stored information that are useful in ideentification and classification of organisms. 

Taxonomical aids
a . Dead 1. Plant( herbarium) 
                2.animals( museum) 
b. Living  1.plant( botanical Garden) 
                 2.animals ( zoological park) 

Some other taxonomical aids
a. Monographs- it gives the complete account of available information  of any one family or genus at a given time. 

b. Manuals- contained complete information about area covered, keys, and description families, genera and species. 

c. Publications- like periodicals and dictionaries are brought to provide information about new additions and updated informations. 

d. Flora- contain the actual account of habitat and distribution of plants of  a given area, these provide the index to the plant species found in a particular area. 

d. Catalogue- contains alphabetical arrangements of species found in a particular area.

Cell structure and cell wall of algae notes

CELL STRUCTURE  CELL WALL FLAGELLA CELL STRUCTURE   On the basis of their organization algal cell maybe differentiate into prokaryotic, mesokaryotic, and Eukaryotic. Prokaryotic are primitive found in Cyanophycean algae characterised by absence of membrane bound organelles, absence of basic protein called histones in DNA.                A Eukaryotic cell have a well organized nucleus and membrane bound organelles.                Mesokaryotic cell has a nuclear membrane and chromosomes(Eukaryotic characters), basic proteins are absent and nucleus division like prokaryotic type (prokaryotic characters). Fou8 in members of Dynophyceae.  1.CELL WALL       Most of the non motile unicellular and multicellular algae possess a typical cellulosic cell wall of non living matter out side the cytoplasmic membrane. It composed of pure or mixed carbohydrate ( cellulose, mucilage, pectin etc.) and substances like alginic acids, fucoidin,, fucin and hemicellulose are present in brown algae

what is Haplodiplontic life cycle ( triphasic)

Triphasic life cycle.       In triphasic life cycle there is a succession of there generation ie may be two haploid generations and one diploid generation or one haploid generation with two diploid generations.it is of following types ie ,   I.Haplobiontic type ( 2 haploid + 1 diploid)         In some rhodophyceae like Batrachospermum two well developed haploid phase are present and the diploid phase is represented by only zygote.                 The haploid plant body bears sex organs ( spermatogonia, carpogonia ) haploid gametes ( sperm and egg)  are formed in these sex organs,a diploid zygote is formed by the fusion of two gametes.the nucleus of the zygote divides meiotically to form four haploid carpogonia ,  they later develop into carposporophyte  generation ( a haploid generation) . the carposporophyte bears carpospores , after liberation carpospores are germinate into heterogeneous chantransia stage ( resting stage) , after this stage a new gametophytic

Mechanism of enzyme action , active sites, interactions, enzyme specificity, lowering of activation energy, notes

Mechanism of enzyme action       The cellular environment normally does not favour a chemical reaction as the biological molecules are quite stable in aqueous environment in the cell at fixed temp and pH. The activation of substrate is prerequisite to overcome the transition state and to proceed the reaction in desire direction.the activation of the substrate is done by the enzyme. How the enzyme decreases the activation energy ,It will be discussed below.    Active sites       The enzymes have a ability to bring the substrate closer and in suitable orientation so as to favour the formation of ES ( enzyme substrate complex ) , the substrate binds to the enzyme at specific place or site called active sites.it is so designed that it will occupy by only the selected molecules, these sites have specific amino acid residues which establish covalent links with the substrate, this links provides the formation of transition state and hence lower the activation energy.each enzyme have different
