2. WHAT IS PHOTOSYNTHESIS?
• The process that occurs in green plants, whereby
solar energy is converted into chemical energy and
stored as organic molecules by making use of
carbon dioxide, sunlight and water.
• WHO OR WHAT CAN PHOTOSYNTHSIZE?
1. Photoautotrophs can photosynthesize.
2. Include: green plants, algae, cyanobacteria and
green protists
3. RAW MATERIALS OF
PHOTOSYTHESIS?
Carbon dioxide,
Sunlight and
Water.
WHY DO PLANTS PHOTOSYNTHESIS?
To provide nutrients and oxygen for heterotrophs
are dependents, because they cannot produce
there own food.
4. PHOTOSYNTHESIS CONSIST OF 2
STAGES:
LIGHT REACTION PHASE DARK PHASE/CALVIN CYCLE
• Dependent on light • Light independent
7. MAIN PIGMENTS USED DURING
PHOTOSYNTHESIS
Chlorophyll a- Absorb violet, blue and red light.
Reflects and transmits green light (that is why plant
leaves appear green).
Chlorophyll b- Absorb violet, blue and red light.
Reflects and transmits green light (that is why plant
leaves appear green).
Carotenoids- Play an accessory role in
photosynthesis. They are shades of yellow and
orange are able to absorb light in the violet- blue-
green range. There pigments became noticeable in
the fall when chlorophyll breaks don.
