Water stress due to lack of water availability limits photosynthesis
Light intensity refers to the amount of light a plant receives
Low light intensity results in limited photosynthesis.
Photosynthesis reaches light saturation at high light intensity
Increasing light intensity beyond saturation does not increase photosynthesis.
Carbon dioxide concentration refers to the amount of CO2 in the surrounding atmosphere
Order the relationship between carbon dioxide concentration and photosynthetic rate:
1️⃣ Low CO_{2}</latex> limits photosynthesis
2️⃣ Moderate CO2 increases photosynthesis
3️⃣ High CO2 leads to saturation
Low CO2 concentrations can significantly limit photosynthesis
Temperature affects photosynthesis by influencing the activity of enzymes
Rubisco functions most effectively at temperatures around 25-30°C.
At high temperatures, enzymes can become denatured
Photosynthesis converts light energy into chemical energy in the form of glucose
The chemical equation for photosynthesis is 6CO_{2} + 6H_{2}O \xrightarrow{light} C_{6}H_{12}O_{6} + 6O_{2}</latex>
In the chemical equation for photosynthesis, light is the energy source
What are the four key factors affecting photosynthesis?
Light intensity, CO2 concentration, temperature, water availability
Low light intensity limits the rate of photosynthesis
Optimal temperatures promote enzyme activity, which in turn increases photosynthesis
Match the factor with its effect on photosynthesis:
Light Intensity ↔️ Increases rate up to a point
Carbon Dioxide Concentration ↔️ Enhances rate to saturation
Temperature ↔️ Affects enzyme activity
Water Availability ↔️ Ensures proper hydration
What happens to photosynthesis when water stress occurs?
It is limited
The overall equation for photosynthesis is: 6CO_{2} +6H_{2}O \xrightarrow{light} C_{6}H_{12}O_{6} + 6O_{2}</latex>. The light in this equation is represented as energy
At high light intensity, photosynthesis plateaus due to light saturation.
When carbon dioxide reaches saturation levels, other factors become limiting
What is the optimal temperature range for photosynthesis?
25-30°C
Order the relationship between water level and photosynthetic rate:
1️⃣ High water level: Optimal photosynthesis
2️⃣ Low water level: Reduced photosynthesis
3️⃣ Water stress: Stomata close to conserve water
Excessive chlorophyll concentration can lead to a plateau in the photosynthetic rate
What happens to the overall photosynthetic rate when one factor becomes limiting?
