Biology Test 1 Study Guide: What defines life/ or something as living? 1. Complex/Organized Structures : Atom Molecule Organelle Cell: Start of living system Tissue Organ Organ System Organism Population Community Ecosystem Biosphere *Also known as Emergent Properties: When living things become more and more complex as it goes from a cell to organ.* 2. Homeostasis: Working to maintain complex structures *ALL living system must do this* We perform this because nature is disordered. Example: Human Body Temperature, keeping the same temperature range. 3. Growth: All living systems must grow before dividin 4. Nutrients and Energy: Two things that need to be acquired = metabolism 5. Adaptive: response capability: responding/adapting depending on the environment. 6. Reproduction: Mitosis/Meiosis Considered the purpose of life 7. Evolution: Traits from natural selection are passed on Genes: segments of DNA Mutations: change in DNA (not negative or positive) Natural Selection: Traits selected from adaptations… adaptations are changes based on mutations Classification of Life’s Diversity 5 Kingdom’s: classified by the following… CELL TYPE: PROKARYOTE (No nucleus) OR EUKARYOTE (w/ nucleus) -KINGDOM MONERA: ONLY PROKARYOTE KINGDOM. CELL NUMBER: MULTICELLUAR or UNICELLULAR -INGDOM MONERA&PROTISTA: UNICELLULAR -KINGDOM PLANTAE, ANIMALIA, FUNGI: MULTICELLULAR NUTRIENT ACQUSITION: INGESTION, ABSORBTION, PHOTOSYNTHESIS= ways to get GLUCOSE -KINGDOM PLANTAE: PHOTOSYNTHESIS -KINGDOM ANIMALIA: INGESTION -KINGDOM FUNGI: ABSORBTION SCIENTIFIC METHOD 1. Observation: Collect & Organize Info. 2. Hypothesis: Must create a hypothesis *You need to test it, in a control experiment* 3. Experimentation: Testing variables so you can know if your hypothesis is correct 4. Reevaluation: conducting the experiment again 5. Conclusion: After reevaluating and double checking, you can form a conclusion. 6. Theory: Based off conclusion you have a theory, when it’s done and believed by multiple people. ECOLOGY: Interrelationships between organisms and their environment A. Organisms: Environment -Are you going to make it through your surroundings? B. Organism: Organism -Do you interact with Intraspecific or Interspecific? -Intraspecific: with a specific species -Interspecific: with different species 2. Population: Members of the same species which interbreed 3. Community: Dealing with members of different species 4. Ecosystem: Biotic (Living) and Abiotic (non-living) components of a habitat 5. Biosphere: All ecosystems on the planet Environment: Abiotic Conditions -Must be adapted to these in order to live: -SUNLIGHT, TEMPERATURE, WATER & SALT, OXYGEN, METABOLIC WASTE, NUTRIENTS, Ph.
