Factors Affecting Photosynthesis Flashcards
What is a Limiting Factor?
A factor which, when in short supply, will reduce the rate of reaction
What is Optimum?
The best or most favourable situation or level
What is Denatured?
When the structure and function of a substance in altered
Which factors affect the rate of photosynthesis?
-Light intensity
-Carbon Dioxide
-Temperature
-Chlorophyll
What does the light intensity provide in photosynthesis?
It provides the energy needed for the endothermic reaction
As light intensity increases, what happens?
The rate of photosynthesis increases
What happens when light is sufficient?
Another factor becomes the limiting factor
As Carbon Dioxide concentration increases, what happens?
The rate of photosynthesis increases
When Carbon Dioxide (CO2) is sufficient, what happens?
Another factor becomes the limiting factor
Why does temperature affect the rate of enzyme-controlled reactions?
-At low temperatures, there are a low number of molecular collisions between enzymes and substrates. At high temperatures, enzymes are denatured.
What is Chlorophyll?
The green pigment in chloroplasts that absorbs the light energy and uses it to carry out photosynthesis
If leaves have increased chlorophyll, what happens?
They will have an increased rate of photosynthesis
What happens when chlorophyll is sufficient?
Another factor becomes the limiting factor.
How can farmers artificially create the ideal conditions for their crops?
Temperature
Light
Water
Carbon Dioxide
Chlorophyll
How can farmers use temperature to artificially create ideal conditions for their crops?
-Keep in a greenhouse
-Heater in warmer
-Ventilation in summer
