Biology – The study of LIFE!
Anything considered alive share the following 7 characteristics
1. Cells All living things are
made of one or more cells
The cell is the basic structure of all living things
2. Reproduction
All living organisms reproduce
Sexual reproduction creates genetic variation
Asexual reproduction creates exact copies
3. Metabolism
Metabolism - All the chemical reactions that create and use energy to run all living processes
Plants capture the energy of the sun and convert it to food
All other organisms eat the plants or they eat the animals that eat the plants
4. Homeostasis
Homeostasis – maintaining a stable internal environment in spite of external changes
Balancing internal conditions with external conditions
5. Heredity
Passing on characteristics to the next generation
Genes carried on DNA are passed from parent to offspring
6. Evolution
Changes in the traits of species over time
Individuals with the best traits for their environment will survive and pass on their genes to the next generation
7. Interdependence The interaction of
living organisms with each other and with their environment
Dependence on one another and the ecosystem
