Which of the following is the correct equation for PHOTOSYNTHESIS?

• 6CO₂ + light + 6H₂O --> 6O₂ + C₆H₁₂O₆

• 6CO₂ + C₆H₁₂O₆ + 6H₂O --> 6O₂ + light

• 6O₂ + light + 6H₂O --> 6CO₂ + C₆H₁₂O₆

• 6O₂ + C₆H₁₂O₆ --> 6H₂0+ Sugar + ATP

Which of these factors woudl not affect the rate of photosynthesis? .

• Light intensity

• Water

• Temperature

• Oxygen levels

• Carbon Dioxide concentration

Answer explanation

sunlight drives photosynthesis

you need water and CO2 since they are the reactants (go in). Having high levels of CO2 drives the opening of the stomata so photosynthesis can take place.

oxygen is a waste product and will not affect the rate of photosynthesis

Most plants appear green because chlorophyll

• absorbs green light.
• absorbs violet light.
• reflects green light.
• does not absorb violet light.

Answer explanation

we see the light colors that are reflected back to us
