THE CHLOROPLAST

• Where Plant Cells
• Make Food

The Plant Cell

• The Chloroplast
• Contains Chlorophyll which traps sunlight
• Where plants make food
• Site of Photosynthesis

3
Your Function

• Site of Photosynthesis
• Combine carbon dioxide and water to make food
• Has chlorophyll, which traps the suns energy and
  uses it to make food

4
What Happens Here

• The Photosynthesis Reaction
• carbon dioxide water energy ? glucose
  oxygen
• C6H12O6 is food that the plant can store.

6CO2 6H2O energy ? C6H12O6 6O2

CHLOROPLASTJob Description

• Get 6 carbon dioxide (CO2) molecules from the
  cytoplasm.
• Get 6 water (H2O) molecules from the cytoplasm.
• Use the atoms from these molecules to make a
  molecule of glucose (C6H12O6). If needed, use the
  glucose molecule diagram on the next slide.
• Have the cytoplasm take the glucose molecule to
  the Vacuole for storage.
• Use the remaining oxygen atoms to make oxygen
  molecules (O2) .
• Have the cytoplasm carry the oxygen molecules to
  the cell membrane where they can be released.

The Product That You Make

• The suns energy is now stored in these chemical
  bonds.
• Later on in cellular respiration, the energy can
  be released for use.
