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
