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.

How does pollution affects the rate of photosynthesis?
pollution effects the whole cycle of photsynthesis.
How does changing the light intensity effect photosynthesis and why?
By changing the light intensity the rate of photosynthesis will either increase or decrease because it is one of the factors that affects photosynthesis. If you increase the light intensity the rate increases but if you decrease the light intensity the rate decreases.
How does enzyme action affect the rate of photosynthesis?
It increases the rate of photosynthesis or vice versa...
How does over supply or under supply of the Co2 concentration affects the rate of photosynthesis?
OVERSUPPLY OF SUNLIGHT the plant will be dry and died UNDERSUPPLY OF SUNLIGHT the plant will be withered
How does the tempurature affect the rate of photosynthesis?
The rate of photosynthesis in relation to temperature forms a bell curve. At low temperatures the enzymes responsibility for photosynthesis have very little energy so the rate of photosynthesis is very slow. If it is cold enough for water to freeze it can be very harmful to a plant. As the temperature increases, the enzymes get more energy so the rate of photosynthesis increases. If it gets too hot the enzymes begin to lose their shape (denature). This means they are unable to function properly and the rate of photosynthesis decreases again. Also, at higher temperatures the stomata close to prevent water loss. This also stops gas exchange which slows photosynthesis even further. If it is hot enough for water to boil this can be very harmful.
Does the solar eclipse affects the photosynthesis?
Yes it affects the process of photosynthesis. As solar eclipse block out some sunlight, the rate of photosynthesis will be slower.
How does pollution affects the rate of photosynthesis?
pollution effects the whole cycle of photsynthesis.
How does changing the light intensity effect photosynthesis and why?
By changing the light intensity the rate of photosynthesis will either increase or decrease because it is one of the factors that affects photosynthesis. If you increase the light intensity the rate increases but if you decrease the light intensity the rate decreases.
How light intensity affects the rate of photosynthesis?
by the bubbles that are produces the closer the faster the bubles move
Does the amount of sunlight affect a leaf?
Yes, it affects the rate of photosynthesis and the grana(where light reactions occur).
How temperature affects photosynthesis not only about its rate?
Photosynthesis happens rapidly when there is sunlight. Sunlight is a main factor necessary for Photosynthesis. So if the temperature is not hot enough, photosynthesis might not happen as rapidly as it happens when the sunlight is directly there.
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?
Could photosynthesis decrease if you increase light-intensity?
Temperature affects the rate. Because of it is using enzymes.
Which describes a disruption in the water cycle that could affect photosynthesis?
Polluted water affects water cycle. It also affects photosynthesis.
How can photosynthesis be increased by increasing the temperature?
Temperature affects living things mainly by affecting the rate of chemical reactions. These are catalysed by enzymes, which are speeded up by increasing the temperature. The Calvin cycle is a series of chemical reactions, so increasing the temperature increases the rate of reactions in the Calvin cycle and so increases the rate of photosynthesis.
How does over supply or under supply of the Co2 concentration affects the rate of photosynthesis?
OVERSUPPLY OF SUNLIGHT the plant will be dry and died UNDERSUPPLY OF SUNLIGHT the plant will be withered
How does enzyme action affect the rate of photosynthesis?
It increases the rate of photosynthesis or vice versa...
