Is It a Living Organism?
• The following slides show 30 examples of living and nonliving things.
• Based on the characteristics of life your group came
up with, decide if each example represents a living organism.
• If the object shown is a living organism, write “Yes.” • If the object shown is nonliving, write “No.”

Answers to Is it a living organism?
Characteristics of Living Things
1. Living things are based on a universal genetic code.2. Living things grow and develop.3. Living things respond to their environment.4. Living things are made up of cells.5. Living things reproduce6. Living things maintain a stable internal environment.7. Living things get and use material and energy.8. Taken as a group, living things evolve.

Feather
No
Feathers are produced by
living cells located in
small pit-like follicles in a bird’s outer skin layer.
As it’s produced keratin is
protruded straight out
from the skin follicle,
enlarging the feather.

Grass
Yes11
Seed
Yes
Seeds may lay dormant for years before conditions
become favorable for germination.
12
Chicken Egg (unfertilized)
No
The yellow yolk is not the egg, but food for the egg.
The egg is a tiny single haploid cell found in
the egg white.
The unfertilized egg is not capable of
reproducing or evolving.
13
Zygote
Yes14
Spore
Yes
Spores are usually haploid and
unicellular. Once conditions are
favorable, the spore can develop into a
new organism which produces
gametes.
Spores are part of the life cycle of a diploid organism.
They are every bit a living organism as the organism that produces them.

Probiotic Yogurt
No21
While yogurt contains live cultures of bacteria, the yogurt itself is not alive.
Potato
Yes
One potato can yield many plants. Just cut it into pieces so that each piece contains a bud.
Place a potato piece cut-side down in a hole, cover it with dirt and
apply water. In time, a potato plant will grow.
22
Leaf
Yes
Many leaves can be cut at the stem and placed back into soil to grow new roots.
This is known as propagation. In
some cases, the stem isn’t even needed.
23
Chloroplast
No
There is evidence that the ancestor of
chloroplasts was once a free-living
cyanobacterium that formed a symbiotic
relationship with another cell. This
merger is believed to have happened about
1 billion years ago.24
Butterfly
Yes25
Pupa
Yes26
Fossil
No
Fossils are a remnant or trace of an
organism of a past geological age embedded and
preserved in the earth’s crust or some
natural material.
27
Hibernating Bear
Yes28
Virus
No
Although viruses have genes and can evolve,
they do not have a cellular structure.
In addition, viruses do not have their own
metabolism, and require a host cell to make new
products.29
Mitochondria
No
There is evidence that the ancestor of
mitochondria was once a free-living
bacterium that formed a symbiotic
relationship with another cell. This
merger is believed to have happened about 2.5 billion years ago.
