In this situation, what was the limiting factor? The limiting factor was CO2 because when it was decreased or increased, it was still able to increase the oxygen production.

What is the limiting factor in photosynthesis?

Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.

Why would it be important to know what the limiting factor is in photosynthesis?

Limiting factors of photosynthesis reduce yields of crops and other economically-important plants. Conditions can be set up in greenhouses and outside tunnels to reduce the effects of limiting factors.

What are the bubbles in the gizmo?

In my opinion, the bubbles are the oxygen that the plant is giving off. On the graph, notice the Oxygen production bar. Move the Light intensity slider back and forth.

Why would it be hard to find the ideal light intensity if the temperature were very hot or cold?

if the temp were extremely hot or cold, then oxygen production would be near zero no matter what light intensity value you use. if the light intensity were very low, then the oxygen production would be near zero no matter what C02 level you use.

Why would it be difficult to find ideal CO2 if the light intensity were very low?

It would be difficult to find the ideal CO2 level with a low light intensity because the plant will have a difficult time trying to survive. It would be very hard considering with no light there's no reaction.

What was the limiting factor gizmo?

The limiting factor was CO2 because when it was decreased or increased, it was still able to increase the oxygen production.

In what conditions is light intensity a limiting factor?

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 were the variables we could manipulate on the photosynthesis lab gizmo?

1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis.

Where does oxygen come from?

At least half of Earth's oxygen comes from the ocean.

Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.

Why is knowing the limiting factor important?

There can be many different limiting factors at work in a single habitat, and the same limiting factors can affect the populations of both plant and animal species. Ultimately, limiting factors determine a habitat's carrying capacity, which is the maximum size of the population it can support.

How do limiting factors affect photosynthesis?

Interaction of factors limiting the rate of photosynthesis -...

• the rate of photosynthesis increases until factors becoming limiting.
• if carbon dioxide concentration is increased, the rate increases further, and then another factor becomes limiting.
• the rate can be increased further if the temperature is increased.

How are limiting factors important to the economics of greenhouses?

Limiting factors are important in the economics of enhancing the conditions in greenhouses to gain the maximum rate of photosynthesis while still maintaining profit. ... Even if there is plenty of light a plant cannot photosynthesise if it has run out of carbon dioxide.

Is water a limiting factor?

Steadily Increasing Demand: Although population growth is the major cause of increasing global water withdrawal levels, the overall rise in demand for water has outpaced population growth by a factor of two. ...

Why is sunlight a limiting factor?

An example of a limiting factor is sunlight in the rain forest, where growth is limited to all plants on the forest floor unless more light becomes available. ... Thus the limiting factors hold down population in an area by causing some individuals to seek better prospects elsewhere and others to stay and starve.

What are the 5 limiting factors of photosynthesis?

Factors That Limit the Rate of Photosynthesis

• The presence of photosynthetic pigments.
• A supply of carbon dioxide.
• A supply of water.
• Light energy.
• A suitable temperature.

Which color of light would you expect to produce the lowest rate of photosynthesis?

Water and oxygen plus light produce carbon dioxide and glucose. B. Water, oxygen and carbon dioxide plus light produce glucose. C.

How will photosynthesis affect oxygen levels?

Through the photosynthetic process plants take up carbon dioxide and evolve oxygen. ... Since then, it has been confirmed by various authors that oxygen cconcentrations in the range 21–100 per cent have a marked inhibitory effect on photosynthesis, particularly at saturating light intensities.

What are the ideal conditions for photosynthesis?

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

How is light a limiting factor in oceans?

how is light a limiting factor in oceans? photosynthesis autotrophs depend on light for their energy. as light decreases, the numbers of photosynthetic plankton and other autotrophs decrease. ... low energy environments where freshwater and saltwater mix.

What is the law of limiting factors explain this with a suitable example?

In 1905, Blackman gave the Law of Limiting factors. When several factors affect any biochemical process, then this law comes into effect. This states that: ... To illustrate the law, suppose light intensity supplied to a leaf is just sufficient to utilize 5 mg of CO2, per hour in photosynthesis.

Which one is the most important limiting factor in photosynthesis?

Carbon dioxide

This concentration is still very low in terms of being the optimum for photosynthesis. Carbon dioxide concentration is therefore an important limiting factor for photosynthesis.

What color of light maximizes the rate of photosynthesis?

Hypothesis: The lights higher on the light spectrum, like blue, would have the fastest rate of photosynthesis because the energy is the highest. The green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it would not be absorbed as much as the other colors.

What would a low number of oxygen bubbles indicate about photosynthesis quizlet?

As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity.

How does this explain the relatively low flow of oxygen in green light?

How does this explain the relatively low flow of oxygen in green light? The leaf doesn't absorb the oxygen, so it reflects the green light, resulting in the low flow of oxygen.
