What makes something alive ?

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

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

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

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

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

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. A - dapt to the environment R - espond to stimuli

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

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

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. E - evolve

Allright let’s see how well you paid attention To review the lab findings…let’s play a little game of…
