What is LIFE? What is LIVING?
Scientists conclude that
a group of things is
living if, at sometime,
the members of the
group meet ALL of the
7 characteristics of life.
- What are some living things?
- What are some non-living things?

What is an ORGANISM?
Any living thing

Living, Non-living & Dead Living-
Meet ALL 7 characteristics of life.
Non-living-
Do not meet ALL 7 characteristics of life.
Dead (once living)-
At one time, met ALL 7 characteristics of life.

What are the 7 Characteristics Of Life?
Organisms are organized.
Organisms maintain homeostasis.
Organisms metabolize.
Organisms respond to their surroundings.
Organisms make more living things.
Organisms pass traits to offspring.
Organisms grow and develop.

1. Organisms are ORGANIZED
Have order - an orderly structure.
Specialized parts do specific jobs, but they all work together.
Individual cells are also organized; each part doing a special job.
Example:
The human body is organized:
Cells>Tissues>Organs>Organ Systems>Organisms

2. Maintain HOMEOSTASIS
Homeo-
the same
Homeostasis
Maintenance of internal environment;
maintaining a constant balance or equilibriumExample: Sweating or shivering to maintain a constant body
temperature.

3. Organisms METABOLIZE. Organisms need power (energy) to perform life functions.
Metabolism is the sum of all chemical reactions carried out by the organism.
Autotroph- “self-feeder”
An organism that has the ability to obtain energy from sunlight or inorganic substances and produce its own food supply.
Energy source- sunlight
Examples- plants
Heterotroph- “other-feeder”
An organism that must get its energy from food sources.
Energy sources- chemicals, other organisms, decaying matter
Examples- animals, fungus

4. Organisms RESPOND to their
surroundings.
Response to a stimulus
Adjusting to a change in the environmentExample: Squinting in the sunlight
Usually temporary
Adaptation
Any structure or behavior that increases an
organism’s chance of survival.
Example: a shell on a turtle

5. Organisms MAKE more living
things.
Reproduction: making more of the species;
producing offspring.
Organisms can only come from other
organisms.
If organisms did not reproduce, the species
would go extinct.

Asexual Vs. Sexual ReproductionA-= no, without
Asexual= without sex
The creation of offspring from
one parent. Produces an
offspring with no genetic
variation; exactly the same as
the parent.
Bacteria, Planarians, Cells
Sexual = with sex
The creation of offspring from
two parents. Produces an
offspring with genetic
variation.
Requires fertilization of an egg
by a sperm.

6. Organisms PASS on their
traits. (Heredity)
Parents pass their traits onto offspring.
Inherited characteristics change over time.
This can lead to evolution.

7. Organisms CHANGE during their
lives.
Growth & Development
Growth: Cells get larger and more numerous.
Organisms develop more/different structures.
Organisms will experience many physical
changes throughout the life cycle.
