Characteristics of Living Things
5 Kingdoms of Living Things
• Animals (humans, elephants, octopus,
birds)
• Plants (trees, grass, weeds, shrubs,
flowers)
• Fungi (mushrooms, molds, yeast)
• Protist (amoeba, paramecium, euglena)
• Monera (bacteria)
Characteristics of Living
Things
1) Are made up of cells
2) Can move
3) Can perform
complex chemical
activities
4) Grow and develop
5) Respond to their
environment
6) Reproduce
Living Things are Made of
Cells
• Cells are the basic
building blocks of living
things
• Cells come only from
other cells
• Single celled called
(unicellular)
• Many celled called
(multi-cellular)
Living Things Can Move
• Why Move?
• Need to move to find
food and shelter
• Need to avoid danger
• Need to search for a
mate
• Plants move to get
more sun/water
Living Things Perform Complex Chemical Activities
• Ingestion-taking in food
(plants make food)
• Digestion- food is broken down into
simpler substances
• Respiration-use oxygen to produce energy
• Excretion-process of getting rid of wastes
Living Things Grow and Develop
• Growth - gaining
cells
• Development-part of
growth process
when dramatic
changes take place
• Metamorphosis
• Life span-maximum
length of time a
species can be
expected to live
Living Things Respond to
their Environment
• Stimulus-any change in
the environment that
produces a response
(smells, noise, light, water,)
• Response-action,
movement, or change
in behavior (blinking)
Living Things Need to
Reproduce
• Living things will
become extinct if they
do not reproduce
• 2 types
(sexual/asexual)
• Sexual - 2 parents
• Asexual - 1 parent
