Photosynthesis

And Cellular Respiration

Photosynthesis Process where

plants and other organisms use the sun’s energy to convert carbon dioxide and water into oxygen and sugars.

How Is It Done? Water enters

through the roots and stomata.

Carbon dioxide enters through the stomata.

Chlorophyll in the chloroplasts is needed.

Two Stages Chlorophyll collects

the sun’s energy. Water & carbon

dioxide combine to make sugar and oxygen.

The equation

Cellular Respiration Cells break down

simple sugars (glucose) and release the energy.– Stored energy

comes from our food.

– Done in all living things.

Two Ways to Get Energy Cellular respiration

– Uses oxygen.– Mitochondria.

Fermentation– Without oxygen.– Done in your

muscles (lactic acid) & yeast/bacteria.

Two Stages Sugar is broken down in the

cytoplasm.

ATP is released in the mitochondria

The Equation

Photosynthesis & Respiration are opposite

reactions.
