Summary Concept (8.1)

The Structure of Chloroplasts

• The organelle where photosynthesis takes place is called a chloroplast.
• Chloroplasts contain chemical compounds called chlorophylls.
• Chlorophylls give the organelles their green color.
• Tiny spores called stomata are found on the surface of the lead.
• Carbon dioxide comes in and goes out of the stomata
• Viens carry water an nutrients from the plants roots to the leaves.
• The inner membrane encloses a thick fluid called stroma.
• The disk shaped sacs in the stroma are called thylakoids.

Chemical Equation for Photosynthesis:

Carbon dioxide+ Water --> --> Glucose + Oxygen

• The light reactions convert energy in sunlight to chemical energy.
• The cycle in plants that makes sugar fom carbon dioxide, H+ Ions and high energy electrons carried by NADPH is called the Calvin cycle.
• The calvin cycle does not require light to begin.
