What is the limiting factor of photosynthesis?

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

Is water a limiting factor for plants?

Although water is required for photosynthesis, it is never considered a limiting factor as if water availability is so low to limit the rate of photosynthesis, the plant would have already closed its stomata and ceased photosynthesis, as a result of other processes stopping.

Is water a limiting factor?

Resources such as food, water, light, space, shelter and access to mates are all limiting factors. If an organism, group or population does not have enough resources to sustain it, individuals will die through starvation, desiccation and stress, or they will fail to produce offspring.

How does water affect photosynthesis?

Water affects the rate of photosynthesis indirectly. Water stress causes the stomata to close, thus reducing the availability of CO2. It also causes the leaves to wilt, reducing the surface area for photosynthesis.

How does water temperature affect photosynthesis?

Higher temperatures will cause photosynthesis to occur more rapidly in plants because as temperature increases, the the molecular activity increases, which causes the reaction to occur faster.

What are examples of limiting factors?

Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

Does water affect photosynthesis rate?

Water affects the rate of photosynthesis indirectly. When the water supply is limited then stomatal closure affects the rate of photosynthesis. Water stress causes the stomata to close and thereby reduces carbon dioxide availability.

What is not a limiting factor of photosynthesis?

However, a high carbon dioxide level is not damaging to the process: the plant simply reaches a maximum rate of photosynthesis where it cannot process it any faster. Water is not generally considered a limiting factor because the amount needed is very small.

Why would water not generally be a limiting factor in the forest?

Because water is recycled constantly through the water cycle, it is a never-ending process with so much water it can’t possibly run out, so this means there is enough water for everyone to survive, and this means it is NOT a limiting factor.

How does less water affect photosynthesis?

Lack of water is especially detrimental to plants because they end up closing their stomata to conserve water. This means that plants also don’t take up as much carbon dioxide as they need. Therefore, photosynthetic activity slows down. On the other hand, too much water can also negatively affect plants.

What are the factors that limit the rate of photosynthesis?

There are a number of factors that interact to make the process of photosynthesis work. Any one of these could become a limiting factor, in Which Water can be considered too. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide.

Is water a limiting factor in plants?

Water is not generally considered a limiting factor because the amount needed is very small. However, lack of water can cause the plant’s stomata to close, which restricts its intake of carbon dioxide.

How does water affect the rate of photosynthesis?

However, lack of water can cause the plant’s stomata to close, which restricts its intake of carbon dioxide. All of these factors interact to either increase or decrease the rate of photosynthesis, and changes in any one of them can seriously affect the process.

Why can’t photosynthesis occur without water?

While it is true that photosynthesis cannot occur without water, the amount of water needed for the process is actually very small. As a result, water rarely becomes a limiting factor. Photosynthesis is much more likely to be limited due to a lack of light, carbon dioxide, or appropriate temperature.
