Different methods of sexual and asexual methods of reproduction in fungi - Medlepius

 FUNGI
Fungi are Heterotrophs but they are special as compared to the animals because animals are ingestive hetero-tropes where as fungi are absorptive hetero-tropes they have chitin in their cell wall and such that so lets come to out topic that is sexual and asexual reproduction in fungi



ASEXUAL REPRODUCTION IN FUNGI
So fungi reproduces sexually as well as asexually so these are some of the common methods by which fungi reproduces are as following

  • spores 
  • conidia
  • fragmentation 
  • budding 

Spores
One of the method through which fungi reproduces asexually are by the spore formation such that spores are formed with the sporangium that is cut of from a complete hyphae such that spores are produces in a very large amount they do not need water for their dispersal they can be dispersed easily by other method such as by wind by animals by human activities by insects and birds coming for nectar by water splashing and by other many means these are some of the activities through which spores are spread they are very resistant to many of the environmental conditions so they an survive for weeks without decaying and without any kind of desiccation


Conidia
They are special structure through which fungi also reproduces asexually they are formed inside conidiophore not inside the sporangium conidiophore are formed by cutting of from the modified hyphae so like the spores they are also produced in very large number and can be dispersed by many of the methods such as by wing by water by rain by water splashing by human activities by insect activities by birds and many more they are also very resistant and can survive unto many weeks till decaying


Fragmentation
So fungi can also reproduces through the fragmentation such that in this the fungi can grow any of its cut part it is defined as the regeneration on cut of part such as in planaria and many other organisms and fungi can also reproduce by the fragmentation

 Budding
Fungi can also reproduces through budding in which apart of a small bud is formed on any side of the body and that may separated any time from the body and can fully grow into an adult such that more than one bud can be formed at a time  
   
SEXUAL REPRODUCTION IN FUNGI
On the basis of sexual reproduction there are several group into which the fungi are divided that are as following

  • zygomycota 
  • ascomycota 
  • basidomycota 
  • deuteromycota 


Zygomycota
In this group pf fungi fusion of nucleus takes place after the fusion of cytoplasm and their is no lengthy dikaryotic phase 


Ascomycota and Basidomycota
In these two groups the fusion of nucleus does not take place after the combination of the cytoplasm and their is length dikartotic phase such that in them two nuclei of different genetic material coexist with each other

Deuteromycota
In this group of fungi there is no sexual reproduction there may be any kind of sexual reproduction but is not found yet but they reproduces by a way known as the parasexuallity and asexually they reproduce by conidia

B efore discussing about a very famous and notorious virus known as corona virus that what is its nature bio-synthetic machinery mode of action history symptoms as well as preventive measures. We should know what a virus actually is and what are some of the properties of viruses that makes it such. So if we want to simply define virus than we can define it as following  Virus is a extremely small infectious agent that only replicates inside the living cells of an organism or it is a non cellular infectious entities that are generally made up of a protein coat and DNA or RNA as its genetic materiel and they lack their own bio-synthetic machinery and they replicate by taking over the bio-synthetic machinery of its host    there are some specific properties or characteristics that are limited to viruses and they are as following they are obligate intracellular parasites  they are extremely small in size  they lack bio-synthetic machinery of their own  viruses have the ability to

digestion and absorption digestion in amoba, hydra, planaria, cockroach

hi hope well thanks for your great support in the previous segments of this blog so in this segment of the blog i would like to talk about digestion and absorption different process that are involved in all of this and digestion and absorption in many of the living organisms such as in hydra amoeba cockroach planaria and and all of the things involved in this and the thing if you want to know anything related to biology so please let me know down in the comment section and please follow my blog to show your great support so                                                         lets start digestion and absorption  *all of the animals have similar requirements but although these requirement differ in detail such that all of the animals must have a constant supply of water oxygen simple sugars amino acids fatty acids minerals and vitamins for their proper growth but the problem is that except water and oxygen not all of these things are found in this form they are found in nature in

class filicinae example of adiantum and its life cycle

CLASS FILICINEAE introduction all the plants that belongs to this group are collectively known as the ferns  features  plants belonging to this group are found all over the globe bu they have their most concentration in tropics  almost of them are found in moist and shady places but some of them can also grow in dry conditions  they can grow in both hilly areas and in plains  some of them are epiphytic and grow on the bank of rivers such that they are parasites  such that they can greatly vary in size  they contain foliar sporangia such that sporangia attached to leaves such a type of leaves are known as fronds when the frond is young and immature they are coiled and this specific pattern of them is known as circinate vernation  examples  example of important ferns are  dryopetris pteridium  adiantum  pteris   ADIANTUM introduction * it is also known as the Maiden Hairfern    * adiantum is a common example of fern that belongs to the class filicinae
