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,Prions, Viroids ,Viruses

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  ...

Biodiversity

Biodiversity on earth and India:- Total species present on earth = 20-50 million Global species diversity on earth = 7 million (Robert May) According to Robert May = 22% of 7 million  species are discovered  discover Plant & Animal species  = more than 1.5 million Indian global diversity = 8.1 [   cover 2.4% Land  ] In India : -  1)  45,000 Plant & 90,000 animal species discovered. 2) lakh Plant & 3 lakh Animal species yet to be discovered  Mega diversity country in world = 12 Biodiversity on earth  1).
