What is Biology? Biology  the study of living things Bio = Life ology = study of Living things are classified into 5 groups: Animals Plants Fungi Protists Bacteria In Biology, we call these the 5 kingdoms of living things.

Living vs. Nonliving Living things Biotic Called organisms https://www.youtube.com/watch?v=p51FiPO2_kQ Living things Biotic Called organisms Made up of CELLS (unicellular and multicellular) Examples: Plants Animals people Non-living things Abiotic “A” = no; not Examples: Soil Rocks Water Air

Synthesis How organisms build necessary molecules Examples: Protein Synthesis: making proteins from DNA Photosynthesis: plants make food using energy from sunlight

Transport How organisms get what they need to cells Examples: Circulation and absorption Active transport; diffusion; osmosis; facilitated diffusion

Excretion How organisms get rid of their waste and balance their fluids Examples: Removing fluids to balance water Removing unused molecules from food

Sweating – reduces body temperature Regulation How organisms control body processes Examples: Important to homeostasis- to maintain balance within the body Short term change based on stimulus (stimulus and response) allows living things to adapt to changes Sweating – reduces body temperature

Nutrients How organisms break down and absorb food Examples: Fungi decompose dead remains (decomposer) Plants make their own food (autotroph) Animals consume other organisms and absorb food (heterotroph)

Grow & Develop How organisms make new cells and develop necessary body parts Examples: Birds develop in an egg Mammals develop in a uterus Fungi develop from a spore Plants develop from a seed Develop – to change due to hormonal or mental cues Grow – to get larger in size; body size

Living things are complex and made up of many levels 5. Organism 4. Organ System 3. Organs 2. Tissues Cells – basic unit of life * Atoms, Molecules *Elements

Muscle cell Muscle tissue Heart Circulatory System/ Organsim

Reproduction How organisms make new individuals like themselves Examples: Prevents Extinction! Sexual vs. Asexual Internal or external fertilization

Respiration How organisms get oxygen and release carbon dioxide to make usable energy A series of chemical reactions that result in the release of energy (ATP) Examples: Anaerobic respiration = no oxygen Aerobic respiration = oxygen Plants exchange gasses
