7 Functions of Life“RRRGMEN” Chapter 8 Section 1 Pages 214 - 217
1. Respiration- oxygen + food carbon dioxide + ENERGY • This occurs in cells! • It is NOT the same thing as breathing, it is a way to make ENERGY
2. Reproduction- to make more (copies)of a species • 2 Different Types • Sexual- involves 2 parents • Asexual- involves 1 parent
3. Response to Stimuli- a reaction to an action • Stimulus- something that causes a reaction or a response • Ex:You shiver when you are cold • Aka.. SENSITIVITY
4. Growth- to develop emotionally & physically over time • Cells multiply • Cells get larger (1x celled organisms)
5. Movement- internal or external motion • Ex: running, heart beating, blood flowing, flowers bending toward sun, trees move water from ground to leaves
6. Excretion- to get rid of waste • Ex: animals go to the “bathroom”, trees release oxygen from leaves
7. Nutrition- to get basic needs met (food, water, nutrients)
Homeostasis- regulation of an organism’s internal conditions, despite change in the environment • Ex: keeping right amount of food, sugar & water in cells • Ex: keeping body temp around 98.6 degrees F
~~Most energy used by organisms comes directly or indirectly from the SUN~~
