Flashcards
The Rate of Photosynthesis.
Cards in this deck (13)
- 1What is a limiting factor?Something that stops photosynthesis from happening any faster.
- 2Name 3 limiting factors.Light
Temperature
CO2 - 3What is the liming factor at night?Light.
- 4What is the limiting factor in winter?Temperature.
- 5If it is warm enough and bright enough, what is the limiting factor?Carbon Dioxide.
- 6Explain an experiment that helps you to workout the ideal conditions for photosynthesis.
- 7Describe a graph that shows that not enough light slows down the rate of photosynthesis.As the amount of light increases, the rate of photosynthesis increases up to a certain point. After that point the rate of photosynthesis doesn't change.
- 8Describe a graph that shows that carbon dioxide affects the rate of photosynthesis.The amount of CO2 will only increase the rate of photosynthesis up to a point. After that point the graph flattens.
- 9Describe a graph that shows that Temperature affects the rate of photosynthesis.The rate of photosynthesis increases until about 45 decrease c where the enzymes start to become denatured.
- 10What is the most common way of artificially crating the ideal environment for plants to grow?Green houses.
- 11How does a green house stop temperature from being the limiting factor?It traps the sun's heat.
- 12How do farmers prevent light from being the limiting factor?They provide artificial light.
- 13How do farmers and gardeners increase the level of CO2 in a green house?By using a paraffin heater that provides heat and produced CO2 as a by-product.
