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
