Characteristics of Living Things 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 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 E xcretion How organisms get rid of their waste and balance their fluids Examples:

Removing fluids to balance water Removing unused molecules from food 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 N utrition 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) G row & 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 Grow to get larger in size; body size Develop to change due to hormonal or mental cues Living things are complex and made up of many levels 5. Organism 4. Organ System 3. Organs

2. Tissues 1.Cells basic unit of life * Atoms, Molecules *Elements Muscle cell Muscle tissue Heart

Circulatory System/ Organsim R eproduction How organisms make new individuals like themselves Examples: Prevents Extinction Sexual vs. Asexual Internal or external fertilization R

espiration 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
