Transcript CHARACTERISTICS OF LIVING THINGS
CHARACTERISTICS OF
LIVING THINGS
1. Made up of Cells
Unicellular – made of one
cell (ex. Ameba)
Multicellular – made of
many cells (more than one
– ex. Human)
2. Can Reproduce
Asexual reproduction – new
organism forms from a single
parent
Sexual reproduction – 2 cells from
different parents unite to produce
a new organism
3. Based on a Genetic Code
Mostly DNA
(Double Helix)
4. Grow and Develop
•Metamorphosis
5. Obtain and use Materials
and Energy
Food & Oxygen
Metabolism – chemical
reactions through which an
organism builds up or breaks
down materials as it carries out
its life processes
6. Respond to their Environment
Fight or Flight
Stimulus – signal to which
an organism responds
Stimulus is produced as a
function of the nervous
system
An organism reacts to
stimuli following a pathway
(neuron) through the
nervous system to produce
a response
7. Maintaining Internal Balance
Homeostasis –
process by which
organisms maintain
a relatively stable
internal
environment (ex.
Body temperature
– hot/cold)
8. Evolution
Taken as a group, living
things change over time
