INGESTION 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 undergo cellular respiration
Does it excrete?
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 downfrom the leaves
Does it excrete?
Yes, it excretes water
Does it undergo cellular respiration
Although a plantmake its own
food ...
… by “breathing” in carbon dioxide
and water from its roots
Which is Photosynthesis
Plants still need to take in Oxygen
For cellular respiration
To burn the food in every cell
of its body
so that is canhave energy for
growth and Life’s Processes
