Limiting  factors of Photosynthesis

There are 3 main factors that limit photosynthesis the 3 main factors are

Another limiting factor is the location of the plant since every factor depends on the location of the plant and by that I mean carbon dioxide, water and the supply of sunlight energy.

How much carbon dioxide there is in the air. If you have a low amount of carbon dioxide if will affect the rate of photosynthesis and if there is a lot of carbon dioxide it is not going to affect the rate of photosynthesis.

Another limiting factor is the temperature it is in the air. The colder it gets specifically between 0 to 10 degrees celsius enzymes do not work properly. Enzymes accelerate chemical reactions and by that I mean that photosynthesis is a chemical reaction.

Another factor that affects photosynthesis is the light intensity. As light intensity increases the rate of photosynthesis increases as long as there is a fair amount of carbon dioxide and water.

There are also many different leaves that have different advantages

Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide.

Limiting factors of photosynthesis
1-Light intensity
As light intensity increases the rate of photosynthesis also increases and therefore when the plant gets less light photons, the efficiency of photosynthesis also decreases.
This is because light is an important part of a plants life cycle, as it allows the plant to transform it into chemical energy.

2. Carbon dioxide levels
Carbon Dioxide is only present in 0.04% of the atmosphere however if for some reason the plant is in an area which has lower levels of concentration the plant will eventually die off.

3. Temperature
Even with the right concentration of of light and carbon dioxide, too cold temperature (below 0 degrees) most plants cannot Photosynthesize. The same goes for heat as most plants (excluding the cactus) will die off, if not adapted properly. This is because Photosynthesis is controlled by enzymes, that are highly sensitive to temperature fluctuations. As temperature increases reaction rate will increase, as reactants have greater kinetic energy and more collisions results. Above a certain temperature however the enzymes begin to die .

limit factors of photosynthesis:

-light: if  the plant doesn’t have enough light it can’t  photosynthesize quickly.

-carbon dioxide: if the plant does not get sufficient carbon dioxide it can’t photosynthesize

-temprature: If it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesize if it gets too hot.

If the plant does not receive a sufficient amount of sun light, the plant will not photosynthesis as it should. Even if there is a large amount of water, it still wont photosynthesis quickly without sunlight.

When there is a low concentration of CO2 in the air, it will not photosynthesis as quickly even with light.

If it is too hot or cold outside, the plant will not photosynthesis as quickly as it should.

Any of these factors can affect the rate of photosynthesis.

Photosynthesis can be limited by three different factors: Light intensity, CO2 concentration and temperature.

Light intensity: Sometimes photosynthesis is limited by the amount of light that is available. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.

Temperature: If it gets too cold the rate of photosynthesis will decrease. If it is too hot, photosynthesis will not take place. If you want your plants to photosynthesise, the ideal weather is tropical weather.

Carbon dioxide concentration: 'Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide.'

Farmers can manipulate these limits by putting their crops in greenhouses. So they can get light 24 7 manipulate the CO2 concentration and manipulate the temperature.

There are 3 main factors that limit photosynthesis. Light intensity, CO2 concentration and temperature.

- Without sun, plants can't grow, that is why more light there is, the faster the process of photosynthesis will happen.

-  CO2 is also extremely important since it's what helps to make glucose and energy. Insufficient CO2 will either slow down or stop photosynthesis.

- If it gets too cold, then  rate of photosynthesis will slow down and it can completely stop with really hot temperature.

Any one of these points can limit photosynthesis extremely.
