Kingdom protista

Kingdom protista

⤿ A cellular / unicellular / single celled Eukaryotas
⤿ primary aquatic
⤿ Boundaries are not limited
⤿ Linked together  to plantae fungi
⤿ flagella  -nt or  +nt
⤿ reproduction ⟶ 1st time sexual reproduction  & 1st time zygote formation
⤿ A sexual reproduction ⟶ binnary,fission ,spore formation
Most extensive nutrition diversity 

  • chrysophytes 
  • Dinoflagellates
  • Euglinoides 
  • Slime moulds 
  • protozoans  

chrysophytes 

➥ Golden algae ( desmids ) & Diatoms ( planktons )
Cilia flagella float passively ,due to presence of stored fats 
➥ Microscopic , Photosynthesis ⟹ Chief producers in ocean
                                                                                     ↳ Diatoms 
➥ Pond ( fresh water ) + marine water
➥ Cell wall  ⟹ silica ⟹ Indestructible

Lichens     ALGAE  + FUNGI ALGAE : - Phycobiont chloroplast  chlorophyll synthesis their own food =  autotrophs prepare / provide food for fungi .  FUNGI :- mycobiont  Heterotrops absorptive mode  provide shelter & absorption of water & minerals from soil . algae + fungi → ( symbiosis relationship ) * mutualism * pollination indicator - lichens do not grow in polluted area     Prions                                          Size = similar to viruses . infectious proteinaceous agent   Proteinaceous  = protein only  Acellular / non-cellular  pathogenic → nerogenic disease causing  (Cattle & Human )   nerogenic disease causing :- Cattels → mad cow disease or BSE =  B ovine spongiform encephalopthy  ...

kingdom Monera

 kingdom Monera most extensive metabolic diversity. all prokaryotes - cellular organization BACTERIA: Name of group Archaebacteria Eubacteria Cyanobacteria Mycoplasma  →Structure-very simple, behavior complex. →Sale member of kingdom-monera. →most abundant microorganisms. E.g.-soilfull hand - having hundred of bacteria  → Everywhere extremely harsh habitat (desert, hot spring, snow, deep oceans) 'or' in(Endo) or on(Ecto) living organism Endo + Ecto = Prasite(living organism) →Rod (bacillus), Spherical(Coccus),Comma(Vibro), Spiral(Spirillus). →Recycling of           ↳Nitrogen(N)           ↳Phosphorus(P)           ↳Iron(Fe)           ↳Sulpher(S) →Some are pathogens to human beings pets, crops, farm animals E.g. Cholera = Vibro cholera        Tetanus = Clostridium tetani        Typhoid=Salmonell...
