Characteristics of Living Things (edited from previous author)
Transcript of Characteristics of Living Things (edited from previous author)
All living things reproduce
Copied from Ben Foster and Marie Chamberlain
Made of cells
Living things have cellular organization, respond to stimuli, need energy, can reproduce, grow and develop, and they contain specific chemicals (nucleic acid).
Respond to stimuli
Grow and Develop
Chemicals of life
If living things could not reproduce, then life could not carry on. The ability to reproduce allows living things to pass their genetics down through the ages. If the human population suddenly stopped reproducing, then the humans would shortly become extinct.
Organisms must be respond to stimuli. If they dont respond to stimuli, then death can occur.
All living things grow and develop. Plants start as small seeds that, over time, grow into towering trees. Animals start as small embryo and develop into beings that when fully grown are mature and reach a height of growth.
Since the first complex organism was formed, living things have evoled into what they are today. All living things today have evolved from their previous forms. Homo sapiens have evolved from apes to the now upright, intellegent beings today. his picture shows what Man has evolved from over time. Most of all living things can be traced back to aquatic life.
In order to be a living thimg
one must be able to maintain
homeostasis. This is the prcess
in which the body is able to
regulate its internal emvironment
to a stable, constant cindition.
If living things were unable to
do this, then their bodies would be
comstantly overheating asnd
freezing causing the seices to
Energy is needed for an organism to do all of the bodily processes.
You have 2 eyes, 2 arms and 1 stomach because that is how the chemicals inside of you are arranged.
Cells are made of specific parts called organelles. Each organelle has its own job that helps the body function properly.
Is a virus alive?
One may think so because it
reproduces inside the body, it is
made of genetic material,
and it has evolved over
time. However, a virus is
in fact not alive. Even though
it follows some of the eight
characteristics of life, it does
not follow all.

Organisms have DNA in their cells which determines what they look like and what they can do. These
are passed from one generation to the next.
Some organisms are
. Some have 8 legs or 100 legs. Some can make noises and some can't even see.
Tiny building blocks called cells make up all living things.
If an organism only has one cell, it is called unicellular (uni = ?)
If it is made of more than one cell, it is called
(multi = ?)
METABOLISM is the total energy for an organism to obtain homeostasis
Examples: dehydration, Diabetes Mellitus, Diabetes Insipidus, poisons
Plants respond to the amount of sunlight and animals respond to the heat by shedding their coats.
HOMEOSTASIS is your body's ability to balance changes in your body.
As organisms get older they grow and they gain the ability to reproduce.
Examples: humans, flowers, larger animals
happens when there are two parent organisms
reproduction happens when there is only one parent
Examples: coral (animal), bacteria
What Defines Life?
AutoTroph - makes its own food
HeteroTroph - consumes other organisms
Offspring = mixture
