Photosynthesis

• Photosynthesis traps the sun's energy and converts CO2 into high energy sugar molecules, glucose.
• Photosynthesis occurs in the chloroplast.
• There are 2 reactions for photosynthesis, light dependent and light independent.
• Light independent can be known as the Calvin Cycle.
• Light dependent uses light directly, and light independent uses light indirectly.
• Both reactions of photosynthesis use sunlight.
• Photosynthesis is conducting synthesis. (Metabolism)
• Photosynthesis gives us food, gives us oxygen, and takes away CO2.
• Photosynthesis requires CO2, H2O, and light.
• Photosynthesis makes glucose.
• Photosynthesis has a waste product of oxygen.
• Photosynthesis provides food for all organisms.
• Photosynthesis provides oxygen to breathe.
• Photosynthesis removes CO2 from the atmosphere.
• Chlorophyll captures energy from sunlight and is a green pigment.
• Light energy from the sun must be captured for photosynthesis to occur.
• Sunlight is 'white' light - a mixture of different wavelengths.
• Photosynthetic organisms capture energy from sunlight with pigments - principally with chlorophyll.
• Photosynthesis usually occurs in leaves.
• The stomata is the opening in leaves that allow for gas exchanges (taking in CO2 and releasing O2)
• The stomata is surrounded by two guard cells which control the opening and closing of stomata.
• The stomata is found on the underside of leaves.
• The chloroplast structure consists of an inner and outer membrane, a stroma, thylakoid, and grana.
• The stroma is the fluid portion inside the inner membrane.
• The thylakoid is interconnected saclike membrane.
• The thylakoid contains chlorophyll inside the thylakoid membrane.
• Grana is a stack of thylakoids.
• Chloroplast picture.

  
• Photosynthesis: 6CO2 + 6H2O + sunlight -> C6H12O6 + 6O2
• 6H2O is being oxidized to 6O2 and loses H+.
• 6CO2 is being reduced to C6H12O6 and gains H+.
• The point of photosynthesis is to make ATP and NADPH.
• Oxygen is a byproduct of photosynthesis.
