CR Bio A Unit 3 Living System Energy

Plants need WATER and CARBON DIOXIDE to make food.

Plants PRODUCE glucose (sugar) and oxygen

What is cellular Respiration?

Cellular respiration is the process in which organisms use O2 to break down food mollecules.

​It occurs in two places.One of the places it occurs is in the cytoplasm.

Where does it Occur?

The Second place it occurs is in the Mitochondria.

Where does it occur?

To Generate usable ATP energy to help support a lot of other reactions in the body.

Why does it occur?

• How carbon is transferred through Earth's spheres

• Does not change form

• Changes what the carbon is bonded to

Carbon

• How water is transferred through Earth's spheres.

• Losing or gaining energy changes the state of the water

  • solid, liquid, gas

Water

• ​liquid to gas

• energy gained

​​Evaporation

• ​gas to liquid

• energy lost

​​Condensation

• liquid to liquid

• energy unchanged

• water droplets just get too big to stay up

​​Precipitation

• liquid to gas

• energy gained

• similar to evaporation only with photosynthesis

​​Transpiration

Carbon goes from being bound in glucose to being bound in CO₂
