The effects of leaf color on rates of photosynthesis.

Photosynthesis consists of light-dependent and light-independent reactions.

what factors affect the rate of photosynthesis?

PREDICTION: I predict that as light intensity increases the amount of
oxygen produced by photosynthesis will increase too.

Assemble the equipment needed to measure the rate of photosynthesis in elodea (water plant).3.

how does light intensity affect the rate of photosynthesis?

Prediction: I predict that the oxygen bubbles will decrease when the lamp is further away from the measuring cylinder, because light intensity is a factor of photosynthesis.

I believe this will happen because when the light source is nearer to the plant more of the plants surface area is coming in to contact with the light from the desk lamp therefore more photosynthesis will occur which will mean more oxygen will be produced which will create more bubbles....


what apparatus can you use to measure the speed of photosynthesis?


In my prediction, I also stated that the rate of photosynthesis will
increase and it did because as the light intensity increased, the
results on the graph increased.

Photosynthesis consists of two connected sets of reactions....

The occurrence of photosynthesis is very important to us as humans, because it provides us with the oxygen we need to breathe and plants are at the bottom of every food-chain and so without them, I would collapse....

Factors that affect the rate of photosynthesis

At temperatures over 40oC enzymes involved in the process are increasingly destroyed, so photosynthesis slows down and eventually stops because the photosynthesis enzymes are destroyed.

What are the Factors that affect Photosynthesis

It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .

Factors affecting the rate of photosynthesis

Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise.

What are the factors affecting Photosynthesis ..

In the future the perhaps it can be studied whether the amount of water greatly affects the photosynthetic rate or if whether a plant is young or old plays a contributing factor.

limiting factors Photosynthesis ..

Furthermore, I predict that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate and more oxygen will be produced and therefore the oxygen levels will increase.
