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
