Synthesis – putting together many small pieces to make something larger ex. Photosynthesis Protein Synthesis CO 2 + H 2 O + Sunlight Glucose + O 2

Transport – moving things throughout the organism ex. Bloodstream moving oxygen & food Plants using roots to move water and nutrients Osmosis Diffusion Active Transport

Excretion – getting rid of wastes ex. Sweating, exhaling, using bathroom

Respiration – NOT BREATHING!! turning food into energy (ATP) ex. Turning lunch into ATP for the rest of the day

Nutrition – taking in nutrients (food, water, oxygen) ex. Breathing in, drinking, eating

Growth & Development Growth – getting BIGGER Development - undergoing changes ex. Puberty & metamorphosis
