Features of organisms

HideShow resource information

Plants

  • Multicelluar
  • Have chloroplasts- photosysis
  • Cellulose cell walls
  • Stores carbahydrates as sucrose (starch)

Animals

  • Multicelluar
  • No chloroplasts
  • No cell wall
  • Nervous co-ordination
  • Respond rapidly to change in enviroment
  • Store carbohydates as a form of glycogen

Fungi

  • Some single celled, others multicelluar with a mycelium body made up of hyphae
  • Lots of nuclei 
  • Can't photosynthesis
  • Cell wall made of chitin
  • Feed by saprotrophic nutrition- secrete extracelluar enzymes into the area outside their body to dissolve their food
  • Stores carbohydrates as glycogen 
  • .e.g. Mucor- multicelluar
  •         Yeast- single celled

Protocists

  • Single celled and microscopic
  • Some have chloroplasts and similar to plant cells (chlorella)
  • Others more like animals (amoeba)

Bacteria

  • Single celled and microscopic
  • No nucleus
  • Circular chromosome of DNA
  • Some photosynsis
  • Most feed off dead or alive organisms
  • e.g. Lactobacillus bulgarius- used to make milk sour and turn to yogurt, rod shaped
  •        Pneumococcur- spheriod in shape

Viruses

  • Particles- smaller than bacteria
  • Reproduce inside living cells- paracite, infect all living organisms
  • Lots of different shapes and sizes
  • No celluar structure
  • Protein coat around genetic material- DNA/RNA
  • e.g. Inflenza virus
  •        Tabacco masaic virus- makes tabacco plants discoloured by stopping them from making choloplasts
  •        HIV
