Basic Life Functions
1. Cellular Respiration
Raw materials Products
C6H12O6 + 6 O2 ________________
Glucose + Oxygen________________
2. Waste Removal
Getting rid undigested food and/or cell waste products.
3. Growth and DevelopmentGetting bigger Changing
4. Reproduction - making a new organism like the original
Asexual ( one parent)
Sexual (2 parents)
5. Irritablility The ability to sense and respond to the environment
Stimulus Response
(change in (reaction of environment) organism)
Animal reflexes
Plant -phototropism
