The rate of photosynthesis will almost always decrease by whichever of several factors is lowest. Some of these include:
1)Sunlight - its Intensity & wavelength.
2)Temperature
3)CO2 and O2 - availability
Sunlight
Generally the more light there is the more photosynthesis occurs. This is true up to a point where the plant has reached maximum photosynthesis levels, so any increase in light intensity will not affect the plant further.
Temperature
Generally a higher temperature is better than cold temperatures for photosynthesis. However if it is humid and the air is saturated with water vapor, photosynthesis is limited. This is because the water vapor being expelled cannot leave and go into the air, as there isn't a concentration difference for it to diffuse across. So the water vapor sits in the leaf, stopping photosynthesis.
CO2
Basically the more CO2 in the air, the better the rate of photosynthesis. Of course CO2 is taken in during the daytime, and if its content was less that normal, photosynthesis couldn't happen normally. Fertilizers increase the number of soil fungi and bacteria, thus increasing the levels of CO2 from their respiration and decomposition processes.
Water and CO2
Plants need water for photosynthesis. If they lack it, they wilt. When they have a deficiency of water, their stoma close, so CO2 cannot diffuse into the leaves. So CO2 is also the limiting factor, although it is as a result of lack of water.
What else can I help you with?
How do different pigments colors affect the rate of photosynthesis?
The wavelength of a color is directly related to the rate of photosynthesis, with longer wavelengths leading to higher rates of photosynthesis.
What are the factors photosynthesis?
The intensity of light, concentration of carbon dioxide and temperature are the three main factors that affect photosynthesis. They determine the rate at which photosynthesis occurs.
Which is the best hypothesis for the scientific question How does light intensity affect the rate of photosynthesis?
A good hypothesis for the question "How does light intensity affect the rate of photosynthesis?" could be: "As light intensity increases, the rate of photosynthesis will also increase, up to a certain point, after which the rate will plateau or decline due to potential factors like chloroplast saturation or damage." This hypothesis is based on the understanding that light is a key factor in photosynthesis, and there are optimal levels of light intensity for maximum efficiency.
What factors can affect the rate of photosynthesis in a plant?
Factors that can affect the rate of photosynthesis in plants include light intensity, carbon dioxide concentration, temperature, water availability, and the presence of chlorophyll. Any imbalance in these factors can limit or enhance the ability of a plant to carry out photosynthesis efficiently.
What ion deficiency is most likely to affect the rate of photosynthesis?
A deficiency in magnesium ions (Mg2+) is most likely to affect the rate of photosynthesis because magnesium is a key component of chlorophyll, which is essential for capturing light energy during photosynthesis. Without enough magnesium, plants may not be able to produce chlorophjsonth and photosynthesis can be negatively impacted.
What factor would least effect upon the rate of photosynthesis in a plant?
The breathing rate of cats. Actually, wait, that might affect photosynthesis. Hmm...good question. If you think about, everything affects photosynthesis. Here is a better question: What DOESN'T affect photosynthsis?
How do different pigments colors affect the rate of photosynthesis?
The wavelength of a color is directly related to the rate of photosynthesis, with longer wavelengths leading to higher rates of photosynthesis.
What are some factors that could affect the amount of photosynthesis in a plant?
What abiotic factors could affect the rate of photosynthesis in a plant?
What are the factors photosynthesis?
The intensity of light, concentration of carbon dioxide and temperature are the three main factors that affect photosynthesis. They determine the rate at which photosynthesis occurs.
What are the factors affect photosynthesis?
Factors that affect photosynthesis include light intensity, carbon dioxide concentration, temperature, water availability, and the presence of chlorophyll. These factors can either enhance or limit the rate of photosynthesis in plants.
What is the testable question for light?
How does the intensity of light affect the rate of photosynthesis in plants?
What are factors affecting photosynthesis?
The intensity of light, concentration of carbon dioxide and temperature are the three main factors that affect photosynthesis. They determine the rate at which photosynthesis occurs.
How does temperature affect the rate of photoysistes?
The higher the temperature, the higher the rate of photosynthesis. Photosynthesis is affected by more than one factor. The other factors are light and carbon dioxide.
Environmental factor that can affect the rate of photosynthesis?
Light intensity is a key environmental factor that can affect the rate of photosynthesis. As light intensity increases, so does the rate of photosynthesis, up to a certain point where it plateaus. Other factors such as temperature and carbon dioxide concentration can also influence photosynthesis rate.
What factors can affect the rate of photosynthesis in a plant?
Factors that can affect the rate of photosynthesis in plants include light intensity, carbon dioxide concentration, temperature, water availability, and the presence of chlorophyll. Any imbalance in these factors can limit or enhance the ability of a plant to carry out photosynthesis efficiently.
What affects the rate of photosynthesis?
The main variables which affect photosynthesis are light, CO2 concentration and temperature. You should be able to explain how each of these has their effect on the rate of photosynthesis. Although water is needed as a raw material for photosynthesis, if water is short, it will cause the plant to wilt (and thereby lose its ability to capture sunlight) long before it limits photosynthesis at the biochemical level. On a deeper level, other factors like amount of chlorophyll, availability of nutrients (eg Mg is needed for chlorophyll synthesis) will also affect the rate of photosynthesis, though these are rarely covered in discussion of this topic.

What are three factors that affect the rate of photosysthesis?
Amount of CO2 available, light intensity and temperature, all effect the rate of photosynthesis.
