1. What are the characteristics of bacteria?

  • Reproduce rapidly, circular chromosome DNA, single celled
  • Do not have a nucleus, have a circular chromosome of DNA, can photosynthesise, single cell, feed off other organisms
  • Feed off other organisms, have a circular chromosome DNA, nucleus, multicellular
  • Small, do not have a nucleus, photosynthesise, no circular chromosome DNA

2. What are the features of viruses?

  • Protein coats, small, these of other organisms, single cells, chloroplasts
  • Protein coates, genetic material, different shapes and sizes, infects all type of living organisms
  • Particles rather than cells, smaller than bacteria, only reproduce inside living cells, in effect all types of organisms, come in all different shapes and sizes, do not have a cellular structure, have a protein coat around some genetic material
  • Have a nucleus, small, reproduce, infect all types of living organisms

3. What do all living organisms have in common?

  • Movement, Respire, Respond, Nutrition, Excrete, Reproduce, Control iInternal Conditons and Grow
  • Movement, Respire, Sense, Nutrition, Respond and Grow
  • Movement, Respire, Respond, Nutrition, Excrete, Reproduce and Grow
  • Respire, Reproduce, Respond, Move, Grow and Excrete

4. What are the features of a plant?

  • Multicellular, have chloroplasts so can photosynthesise, have cell walls made of cellulose, store carbohydrates as sucrose or starch
  • Store carbohydrates is sucrose of starch, multicellular, have chloroplasts so they can photosynthesise
  • Do not have chloroplasts, have cell walls, store sucrose or starch, single cellular
  • Cannot photosynthesise, have cell walls made of cellulose, still carbohydrates

5. What is sapotropic nutrition?

  • It is the secretion and taking in other enzymes from outside of their body
  • It is the way that fungi feed from the outside of their body
  • They secrete extracellular enzymes into the area outside their body to dissolve their food so they can then absorb the nutrients
  • They secrete enzymes into the outside area of their body and then take the nutrients in again
