B8 - Photosynthesis

Question 1

What is the equation of Photosynthesis?

Answer 1

Carbon Dioxide + Water ->(light) Glucose + Oxygen

Co2 + H2O ->(light) C6H12O6 + 6O2

Question 2

What are the three limiting factors of photosynthesis?

Answer 2

Light Intensity
Temperature
Carbon Dioxide Concentration

Question 3

What increases with light intensity?

Answer 3

Rate of photosynthesis

Question 4

What increases with carbon dioxide concentration?

Answer 4

Rate of photosynthesis

Question 5

What increases with temperature?

Answer 5

Rate of photosynthesis

Question 6

Name 5 leaf adaptations

Answer 6

• leaves are broad, giving them a big surface area for light to fall on
• leaves are thin for quicker and easier diffusion
• contain chlorophyll to absorb light
• they have veins, which bring in water to the cells and remove products of photosynthesis
• have air spaces that allow CO2 to get into the cells, and oxygen to leave
• have guard cells that open and close the stomata to regulate gas exchange
