Characteristics of
Living Things
1. Living things
are made up of
units called?
CELLS
Cells can be unicellular
• The prefix “uni” means one
and unicellular organisms
live as a single cell.
• Examples: Bacteria and
Yeast.
BACTERIA
YEAST
Cells can be multicellular
Cells can be colonial
• Colonial organisms
live in groups of
individual cells that are
attached to each other,
but have few
specialized structures.
2. Living things reproduce
Can be Asexual
Sex in science refers to
the exchange of
genetic information.
Budding, as this
yeast is
demonstrating,
requires no DNA
exchange.
3. Living
things are
based on a
universal
genetic
code called
DNA
4. All things grow and
develop
5. Living things obtain
and use materials and
energy
Metabolism
• An organisms total energy spent
using chemical reactions to
break down and build up
materials to carry out life
processes is called it’s
metabolism.
6. Living things respond to
their environment
7. Living things maintain a
stable internal environment
Homeostasis
• The process by which
organisms keep their internal
conditions relatively stable is
called homeostasis.
8.Taken as a group, living
things change over time.
Adaptation
• A genetic trait that is
inherited (you are born with)
that makes you more
successful or better able to
survive.
Evolve
• Although individual organisms
experience many changes during
their lives, the basic traits they
inherited from their parents do not
change. As a group, however, any
given kind of organism can evolve,
or change over time.
