What affects the rate of photosynthesis answer key?
Three factors that affect the rate of photosynthesis are temperature, light intensity, and the availability of water. dioxide.
What factor could be increased to allow the rate of photosynthesis to keep increasing past 50 lux?
Carbon dioxide is needed for photosynthesis. Increasing the carbon dioxide concentration increases the rate of photosynthesis, provided the plant is warm enough, and has plenty of light and water. The maximum rate is determined by the other factors involved.
What is the limiting factor in photosynthesis lab?
Light. As light intensity increases so too does the rate of photosynthesis until a certain point where the graph levels off. At lower light intensities, light is the limiting factor because an increase in light causes an increase in photosynthesis.
What affects the rate of photosynthesis worksheet?
Many things affect the rate (speed) at which photosynthesis occurs: the amount of light (light intensity), the temperature, and the amount of carbon dioxide are a few factors. Scientists know that temperature affects the speed of chemical reactions. Photosynthesis is a series of chemical reactions.
What are the 4 factors that affect the rate of photosynthesis?
The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.
Why is temperature a limiting factor of photosynthesis?
Temperature. The chemical reactions that combine carbon dioxide and water to produce glucose are controlled by enzymes . At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrates. At high temperatures, enzymes are denatured .
What is meant by limiting factor?
A limiting factor is anything that constrains a population’s size and slows or stops it from growing. Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor.
How do you find the limiting factor?
To determine which compound is limiting, we simply divide the number of moles of each reactant by the coefficient on that reactant from the balanced chemical equation, and look for the smallest value.
What are 5 limiting factors?
They are (1) keystone species, (2) predators, (3) energy, (4) available space, and (5) food supply. In biology, the term limiting factor is defined as an environmental factor or variable that has the capacity to restrict growth, abundance, or distribution of a population in an ecosystem.
What are some factors that could limit photosynthesis?
#44 Limiting factors in photosynthesis. Limiting factor is something present in the environment in such short supply that it restricts life processes. Three factors can limit the speed of photosynthesis – light intensity, carbon dioxide concentration and temperature .
What are six factors affect photosynthesis?
6 Factors Affecting Photosynthesis and Its Explanations Carbon dioxide concentration. Carbon dioxide concentration is the most important external factor affecting the rate of photosynthesis of plants. Water Availability. Water is one of the basic needs for plants to be able to perform photosynthesis. Light. Chlorophyll. Nutrient elements. Temperature.
What factors influence the rate of photosynthesis?
There are several factors which affect the rate of photosynthesis as described below: Light intensity. The intensity of light influences the rate of photosynthesis. When other factors are not limiting, the rate of photosynthesis increases almost linearly with increase in light intensity.
What light intensity is best for photosynthesis?
Light Intensity. The light intensity range for most plants falls between 1,200 and 2,000 lumens (measurement of light intensity). The number of light photons hitting the chlorophyll pigments increase as the light intensity rises. This in turn increases the rate of photosynthesis.
