KEY CONCEPT The overall process of photosynthesis produces sugars that store chemical energy.
Photosynthetic organisms are producers or autotrophs. • Producers make their own source of chemical energy. • Plants use photosynthesis and are producers. • Photosynthesis captures energy from sunlight to make sugars– in the form of glucose.
• Chlorophyll is a molecule that absorbs light energy. • In plants, chlorophyll is found in organelles called chloroplasts… therefore, photosynthesis in plants occurs in the chloroplasts. chloroplast leaf cell leaf
Photosynthesis in plants occurs in chloroplasts. • Draw one on your notes… grana (thylakoids) chloroplast stroma
• The chemical reaction make sugars ( glucose) – needs carbon dioxide from the atmosphere
– REQUIRES LIGHT (Sunlight) & WATER – Oxygen is released
The equation for the overall process is: 6 CO 2 + 6 H 2 O C 6 H 12 O 6 + 6 O 2 (Carbon Dioxide) + (water) (Glucose) + (Oxygen)
