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 field of genetics.Brophytes are the at basic stage of plant evolution. As they ressemble the basics of the plants supportive mechanism in land, they can be extensively used in research activities. Mechanism of sex determination in plant is first discovered in liverworts.

3) PACKING MATERIAL

Bryophytes can act as packing material for fragile goods (seedling) i.e, trans shipment of cutting material such as glassware,bulbs etc.

4) FOODS

Bryophytes have also the nutritional benifits. It provides food for herbaceous mamals, birds and other mammals.

5) AS AN INDICATOR

It act as indicator for acidity and basicity of soil.
When in an area polytrichpous grows the is said to be acidic in nature. Similarly When tortella species grows in the soil the soil is said to be basic in nature.

6) Bryophytes also helps in Peat-Tar (coal) formation. If we can harness the correct approach of bryophytes real potential then we can aslo make bio-fuel. This will help in significant reduction in emisson of freenhouse gases. global warming,climate change and other global issues can be strategically tackled by implementation of such sustainable nature intuned concepts.

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
