LIFE Characteristics of life Exercise Properties of life 1. Order 2. Cellular structure 3. Similar chemical compounds 4. Information of cellular structures and their functions 5. Reproduction 6. Lifecycle 7. Metabolism 8. Homeostasis 9. Response to stimuli 10. Evolution 1. Order Cellular structure 3. Similar chemical compounds - chemical elements are recycled → decomposition - proteins, carbohydrates, lipids, water, nucleic acid 4. Information of cellular structures and their functions - DNA → genes → proteins - mutations - replications → reproduction 5. Reproduction - asexual and sexual reproduction - information in genes can be transferred to new generations - evolution (adapting to changes in the environment) 6. Life cycle - video - birth → growth → death 7. Metabolism - biochemical reactions in organisms, essential for staying alive - need for energy - eg. breaking down nutrients and building molecules 8. Homeostasis - “stedy state” - maintaining internal conditions constant - temperature, pH - eg. thermoregulation 9. Response to stimuli 10. Evolution - Mutations in genes create new alleles → new characteristics → evolution Why are viruses not considered to be living beings? Search for information and make notes!
