How does the tempurature affect the rate of photosynthesis?

Answer 1

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.

Answer 2

It tells you that temperature affects the rate of photosynthesis. At low temperature, the rate is slow, while at higher temperatures it is faster. This is true up to a point, known as the optimum temperature, where rate is fastest. After this, the rate slows down and stops as it becomes too hot, the enzymes become denatured and so can't carry out photosynthesis.

Answer 5

Usually, the colder it is outside (like in the winter) the rate of photosynthesis slows down. In the spring when the temperature is warmer than the winter, that is when the rate of photosynthesis starts to speed up.

Answer 6

It provides the enzymes responsible for photosyenthesis more energy, thus increasing the rate of photosynthesis.

Answer 7

Yes, it does.

Other things that affect the rate of photosynthesis is light intensity and the availability of water.

Answer 8

Photosynthesis is driven by enzymes. Enzymes are affected by temperature.
