This document discusses the seven key characteristics of living things: movement, metabolism, respiration, sensitivity/responsiveness, growth, reproduction, and excretion. It defines each characteristic and provides examples. The document aims to help the reader understand and identify the characteristics of living organisms.

2. You WILL be able to:
• list and define the characteristics of living organisms
ClickBiology

3. There are 7 characteristics:
•
•
•
•
•
•
•
•
Movement
Metabolism
Respiration
Sensitivity/
responsiveness
Growth
Reproduction
Excretion
Nutrition
ClickBiology

4. Movement
• An action by an organism or part of an
organism causing a change of position or
place.
ClickBiology

5. Respiration
• The chemical reactions that break down
nutrient molecules in living cells to release
energy.
ClickBiology

6. Sensitivity
• The ability to detect or sense changes in
the environment (stimuli) and to make
responses.
ClickBiology

7. •A REACTION
THAT A LIVING
ORGANISM DOES
IN RESPONSE TO
A STIMULUS.
ClickBiology

8. • Stimulus
–Anything that causes
a response to react.
–Example: if you touch
a hot object, you will
automatically pull your
hand back
ClickBiology

9. Growthin size
• A permanent increase
and dry mass by an increase
in cell number or cell size or
both.
ClickBiology

10. • Is a process by which
living organisms get
bigger.
• A. cells increase in size
• Each cell becomes
larger.
ClickBiology

11. Reproduction
• THE PROCESS THAT MAKE
MORE OF THE SAME KIND
OF ORGANISM
ClickBiology

12. •A life functions that
provides new living
things to take place of
those old ones that die.
It provides continuation
of species.
ClickBiology

13. Excretion
• The removal from organisms of
toxic materials, the waste
products of metabolism
(chemical reactions in cells
including respiration) and
substances in excess of
requirements.
ClickBiology

14. • The taking in of
nutrients
which
are
organic
substances
and
mineral
ions,
containing
raw
materials
or
energy for growth
and tissue repair,
absorbing
and
assimilating them.
