Study Notes
Essential Life Processes
- Living organisms are distinguished from non-living things by their ability to perform essential life processes
- These processes are necessary to maintain life and sustain living organisms
Characteristics of Life
- The ability to perform essential life processes is what distinguishes living organisms from non-living things
- These processes are characteristic of all living organisms, from simple bacteria to complex humans
Maintenance of Life Processes
- The function of maintaining life processes is called metabolism
- Metabolism involves the coordination of various biochemical reactions to sustain life
Examples of Essential Life Processes
- Nutrition: the process of obtaining energy and nutrients from the environment
- Respiration: the process of obtaining oxygen and releasing carbon dioxide
- Transportation: the process of moving substances and waste products within the organism
- Regulation: the process of maintaining homeostasis and responding to stimuli
- Growth and Development: the process of increasing in size and complexity
- Reproduction: the process of producing offspring
- Excretion: the process of removing waste products
The Only Known Planet with Life
- Earth is the only known planet having life according to the text
