LIFE PROCESSES
NUTRITION
INGESTION
EXCRETION
DIGESTION
NUTRITION
INGESTION
DIGESTION
What is the difference between
ingestion and digestion?
Digestion is the break-down of
food into small particles
TRANSPORT
Movements of
“cellular” wastes
Movement of
nutrients
Digested food nutrients must
be carried to other parts of the
living thing to “feed it”
EXCRETION
Waste products
Where do they
come from ?
Name 2 waste products in animals:
Urine and Bowel Movements
RESPIRATION
Not talking
about breathing
Talking about
“cellular
respiration”
Cellular respiration IS the process of
getting energy from food !
Occurs in every cell!
Cellular respiration IS the process of
getting energy from food !
Occurs in every cell!
What is cellular respiration?
Every cell burns “food” to produce
energy to perform that cell’s functions.
In order for something to burn,
what must be present?
Cellular respiration IS the process of
getting energy from food !
Occurs in every cell!
What is cellular respiration?
sugar + oxygen
carbon dioxide + water + energy
Cellular respiration IS the process of
getting energy from food !
Occurs in every cell!
Sugar + oxygen
carbon dioxide + water + energy
What happens to the Carbon dioxide?
…transported OUTof the living thing
Cellular respiration IS the process of
getting energy from food !
Occurs in every cell!
Sugar + oxygen
carbon dioxide + water + energy
Where is the Carbon dioxide produced?
… originally in the cells
Cellular respiration IS the process of
getting energy from food !
Occurs in every cell!
Sugar + oxygen
carbon dioxide + water + energy
Where is the Carbon dioxide produced?
… mammals then “breathe” it out
Cellular respiration IS the process of
getting energy from food !
Occurs in every cell!
Sugar + oxygen
carbon dioxide + water + energy
What happens to the water?
… transported out, collected as urine
Cellular respiration IS the process of
getting energy from food !
Occurs in every cell!
Sugar + oxygen
carbon dioxide + water + energy
What happens to the energy?
… used by every cell of the body
WHY?
WHY
NOT?
Does it
ingest/digest?
Does it
transport?
Does it
excrete?
Does it undergo
cellular respiration
Does it undergo
cellular respiration
Do fish breathe oxygen?
Why do they need oxygen?
How do they get the Oxygen?
Does it take in
nutrition
YES
Through the roots
Does it
transport?
Yes, Water goes
up from the roots,
food goes down
from the leaves
Yes, it excretes water
Does it
excrete?
Does it undergo
cellular respiration
… by “breathing”
in carbon dioxide
and water from
its roots
Although a plant
make its own
food ...
Which is
Photosynthesis
Plants still need to
take in Oxygen
To burn the
food in every cell
of its body
For cellular
respiration
so that is can
have energy for
growth and
