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 u...

What are theHARMFUL OR NEGATIVE IMPORTANCE OF ALGAE

-
NEGATIVE INPORTANCE OF ALGAE


Excessive growth of algae in ponds and lakes makes the water unpotable. 

 The common problem of potable water associated Press algae are
-decomposition of Al imparts  bad taste and odour. 
-forms toxic substances affect on body. 
-efficiency of water filters decrease due to its decomposition. 
-cause corrosion of water pipes and boilers. 


PARASITISM AND TOXICOTY

-Excessively growth of algae may lead to death of aquatic animals and plants. 
-todi secreted by them killed the fishes( affected the nervous system and muscular system). 

- Algae like Alabama, Macrocystis form bloom in warm water. 
-many planktonic form enter into human body along with draining water and cause diseases.. 
-cephaleuros, a member of chlorophyceae occurs as a parasites in angiospermic plants like tea and causes" Resd rust of tea".


 

All the best... 😀😀😀😀😀

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, ...

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 ar...
