AIM: What are life processes? Describe the vocabulary terms.

ingestion, excretion, digestion, respiration, transport. Nutrition ingestion, excretion, digestion, respiration, transport. Nutrition AIM: What are life Processes?

LIFE PROCESSES RESPIRATION NUTRITION TRANSPORT EXCRETION Reproduction

LIFE PROCESSES RESPIRATION NUTRITION TRANSPORT EXCRETION INGESTIONDIGESTION

NUTRITION INGESTIONDIGESTION 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 down from the leaves

Does it excrete? Yes, it excretes water

Does it undergo cellular respiration Although a plant make 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 can have energy for growth and Life’s Processes
