Explain each concept

□ All living things share the six characteristics of life.

□ Organisms are made of one or more cells. Cells are structures that are the basic units of life.

□ Organisms detect stimuli in their environment and respond to those stimuli.

□ Organisms work to keep their internal environment stable with homeostasis.

□ Organisms reproduce asexually or sexually to make more organisms like themselves.

□ The passing of characteristics from parent to offspring is called heredity.

□ Organisms grow and may also change during their lifetime.

□ Organisms use energy to carry out the chemical activities of life. Metabolism is the sum of an organism’s chemical activities.
