Animal and Plant Nutrient Absorption How do organisms get the nutrients they need?

What do animals need?  They need energy in the form of….  How do they get it?  Ingestion  Digestion

The Animal Digestive System  Structures  Mouth  Esophagus  Stomach  Small intestine  Large intestine

What do these do??  Mouth  Mechanical Digestion  What does that mean?  Esophagus  Travel tube  Stomach  Chemical Digestion

What do these do??  Small Intestine  Nutrient absorption  Large Intestine  Water absorption  BOTH use microvilli

So now here’s the question…  How do plants get their nutrients??  What do the roots do?  What do the leaves do?

You should know about the Leaves…Right?  Chloroplasts for sunlight  Stomata for CO2  So what about water?

Roots  Absorb water  Absorb other nutrients (like minerals)  Oxygen

Nutrient Absorption

Now that these organisms have the nutrients, how do they get it to the places it needs to go?
