Aim: How are living things different from non-living things?
Do Now1. What do you have in common with other
living things?2. Explain what a life process is.
Similarities Amongst Living Things• made of one or more cells-->unicellular vs.
multi-cellular organisms• Carry on life processes or life functions
Metabolism
• All life functions or processes together• Chemical reactions that take place in your
body are part of your body’s metabolism
Life Process-Nutrition
• Taking in food• Breaking down food into small nutrients
(digestion)• Getting rid of undigested food (elimination)
Life Process-Transport
• Taking materials into the organism (living thing) & spreading or circulating the material throughout the organism
• Things like oxygen, nutrients, etc.
Life Process-Respiration
• Producing energy from breaking down nutrients into smaller pieces (chemical reaction)
• ATP energy is the energy that cells need to function
• Cellular respiration is the name for the process that makes energy !
Life Process-Excretion
• Removing metabolic wastes produced from life processes
Life Process-Synthesis
• All chemical reactions that use small molecules to form larger molecules
Life Process-Regulation
• Control & coordination of all life activities by nerves & chemicals in the blood (hormones)
• Maintains body homeostasis (stability or balanced internal environment)
Life Process-Growth
• Increase in size or number of cells in the organism
Life Process-Reproduction• Producing new individuals babies, offspring• Not needed for survival
Life Process-Locomotion
• Moving from place to place
