  1. What makes something alive ?

  2. What are living things? Do ALL 9 criteria have to be met? There are certain criteria that determine if something is living. Yes, ALL 9 criteria must be met.

  3. Organism • Anything that possesses all of the following characteristics of life. • Living things R-CHARGEED !!

  4. R - eproduce All living things produce offspring. Making copies of individuals by genetic transfer, sexually or asexually.

  5. Cross-section of worm Leaf Centipede C - ells -Living organisms show an orderly structure (made up of cells) Examples:

  6. The human body maintains an average temperature of 98.6 ºF. H - omeostasis The ability to maintain internal conditions separate from an outside environment. Example:

  7. A - dapt to the environment R - espond to stimuli A living organism will respond to an environmental condition called a stimulus. An adaptation is any characteristic of an organism that improves its chances of surviving in its environment A plant growing in a specific direction due to a light stimulus.

  8. Living Things Adjust To Their Surroundings • -living things interact with the environment • -environment- biotic (living) and abiotic (nonliving) factors that an organism must constantly interact with (air, water, temperature, other organisms, etc.)

  9. G - rowth Getting Bigger / Increasing material D - evelopment • All of the changes that take place during the life of an organism. Maturing. Growth rings in a tree Amoeba absorbing nutrients

  10. Growth-increase in number of cells

  11. Transforming glucose into ATP for energy (to do work). E - energy Metabolism. Chemical and energy transformations. All organisms need energy for all life activities. Even thinking requires a considerable amount of energy.

  12. E - evolve The gradual accumulation of adaptations due to environmental stimuli. (Organisms with more suitable adaptations are more likely to survive and reproduce) Example: Owls, and other nocturnal animals have evolved large eyes for better night vision.
