What is the process of photosynthesis?
Photosynthesis is the process that produces food in plants the food it produces is glucose
What is the energy change for photosynthesis?
Light energy to chemical energy
What is the word equation for photosynthesis

What is the chemical symbol equation for photosynthesis?
6CO2 + 6H2O —> C6H12O6 + 6O2
How does the temperature affect the rate of photosynthesis?
As the temperature increases, so does the rate of photosynthesis - up to a point
How does the carbon dioxide concentration affect the rate of photosynthesis?
Increasing the concentration of carbon dioxide will only increase the rate of photosynthesis - up to a point
How does the light intensity affect the rate of photosynthesis?
if the light intensity is increased, the rate of photosynthesis will increase steadily, but only up to a certain point
How is the structure relief adapted for photosynthesis?
- Leaves a broad there’s a large surface area exposed to light.
- The waxy cuticle helps to reduce water loss by evaporation
