level questions: Factors of photosynthesis

QuestionAnswer
Various elements that influence the speed of photosynthesis, including light intensity, carbon dioxide concentration, and temperature.Factors Affecting Photosynthesis
Name three factors that can affect the rate of photosynthesis.Light intensity, carbon dioxide concentration and temperature are the three factors that can affect the rate of photosynthesis
The level of brightness or illumination, influencing the speed of photosynthesis.Light Intensity
How does light intensity impact the rate of photosynthesis?Photosynthesis happens faster at higher light intensities because light provides the energy needed for the process.
The amount of carbon dioxide available in the environment, influencing the rate of photosynthesis.Carbon Dioxide Concentration
Why does an increase in carbon dioxide concentration enhance the rate of photosynthesis?The higher the concentration of carbon dioxide, the faster the rate of photosynthesis, as carbon dioxide is a raw material needed for the process.
The degree of heat in the environment, affecting the rate of photosynthesis.Temperature
How does temperature influence the rate of photosynthesis?At higher temperatures, the rate of photosynthesis increases because reactant molecules have more energy, leading to more successful reactions. However, very high temperatures can denature enzymes, causing photosynthesis to stop.
Conditions necessary for photosynthesis, and if any are in short supply, they can restrict the rate of photosynthesis.Limiting Factors
What is a limiting factor in photosynthesis?A limiting factor is a condition that, if in short supply, prevents photosynthesis from happening any faster.
The limiting factor during nighttime photosynthesis is the absence of light.Light Intensity Limiting Factor
Why is light the limiting factor at night for photosynthesis?At night, there's little light, which makes it the limiting factor even if other conditions such as carbon dioxide and chlorophyll are present.
The situation where raising the light intensity results in an increased rate of photosynthesis.Increased Light Intensity
What happens to the rate of photosynthesis when the light level is increased?The rate of photosynthesis increases with an increase in light level.
When, despite increased light levels, the rate of photosynthesis reaches a point where further increases in light no longer make a difference.New Limiting Factor
What occurs when increasing the light intensity further stops affecting the rate of photosynthesis?At this point, something else has become the limiting factor.
Graphical representations illustrating the relationship between the rate of photosynthesis and various factors.Photosynthesis Graphs
What can photosynthesis graphs show?Photosynthesis graphs can demonstrate the impact of multiple limiting factors on the rate of photosynthesis.
Conditions affecting the rate of photosynthesis that can be depicted on a graph.Limiting Factors in Photosynthesis Graphs
Can a graph show more than one limiting factor?Yes, graphs can show the impact of multiple limiting factors on the rate of photosynthesis.
The condition initially restricting the rate of photosynthesis, as seen in the early stages of the graph.Initial Limiting Factor
What is the initial limiting factor in the photosynthesis graph?In the example given, carbon dioxide concentration is the initial limiting factor.
The point on a graph where the rate of photosynthesis levels off, indicating that the limiting factor has changed.Constant Rate
What does a constant rate on a photosynthesis graph suggest?When the rate becomes constant, it signifies that the initial limiting factor, such as carbon dioxide concentration, is no longer limiting the rate.
Another condition, such as temperature in this example, that becomes a limiting factor after the initial one is no longer limiting.Second Limiting Factor
In the example provided, what is the secondary limiting factor?Temperature becomes a limiting factor after the rate levels off, leading to a further increase in the rate of photosynthesis when the temperature increased.
The principle stating that light intensity is inversely proportional to the square of the distance from the light source.Inverse Square Law
What is the relationship between light intensity and distance according to the inverse square law?There is an inverse relationship between distance and light intensity; as distance increases, light intensity decreases.
The relationship where two variables change in the same direction; in this case, the rate of photosynthesis is directly proportional to light intensity.Direct Proportionality
How is the rate of photosynthesis related to light intensity?The rate of photosynthesis is directly proportional to light intensity.
The relationship where two variables change in opposite directions; in this case, the rate of photosynthesis is inversely proportional to the distance from the light source.Inverse Proportionality
What happens to the rate of photosynthesis as the distance from the light source (lamp) increases?If you move a lamp away from a plant, photosynthesis happens more slowly because the rate of photosynthesis is inversely proportional to the distance from the light source.
Illustration of the inverse square law, such as if the distance is doubled, the amount of light reaching the plant is quartered.Example Calculation
What happens to the amount of light reaching the plant if the distance is doubled, according to the inverse square law?If the distance is doubled, the amount of light that reaches the plant is quartered.
