protctists, bacteria, viruses

• protoctists


  single-celled+microscopic, SOME HAVE CHLOROPLASTS (similar to plant cells), others are like animal cells
• examples of protoctists


  chlorella (plant-cell like), amoeba (animal-cell like- lives in pond water)
• where can amoeba be found

  in pond water
• bacteria


  prokaryotic, single celled+microscopic, DONT HAVE A NUCLEUS, contain a circular chromosome of DNA, SOME CAN PHOTOSYNTHESISE, most feed off other living organisms (living+dead)
• how is DNA represented in bacteria

  as a circular chromosme
• examples of bacteria


  lactobacillus bulgaricus (used to make milk sour and turn into yogurt) + rod-shaped, pneumococcus (spherical round shape)
• what is lactobacillus bulgaricus used for 


  to make milk sour and turn into yogurt
• shape of pneumococcus


  spherical round shape
• shape of lactobacillus bulgaricus

  rod-shaped
• viruses


  NOT LIVING ORGNANISMS, particles rather than cells (smaller than bacteria), only reproduce inside living cells, ARE PARASITES, infect all types of living organisms, come in diff shapes+sizes, have a protein coat around genetic material instead of cellular structure
• where do bacteria feed off

  other living or dead organisms
• why are viruses referred to instead of cells

  particles
• where can viruses reproduce

  living cells
• what is a parasite (virus)

  depends on other organisms to grow and reproduce
• what do viruses have instead of a cellular structure

  protein coat around genetic information (DNA/ RNA)
• exmaples of viruses 


  influenza virus, tobacco mosaic virus, HIV
• what is the tobacco mosaic virus

  makes leaves of tobacco plants discoloured by stopping them from producing chloroplasts
