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
