Oxygen that is produced in photosynthesis is given off as a gas.

This is why often comparing one 6500K lamp to another can often be "apples to oranges" as for necessary useful light energy (PUR) needed by plants or corals. Another reason why Kelvin ratings are often poor methods to rate modern aquarium lights.

Aim: We will be trying to see if light intensity has an effect on the rate of photosynthsis.

The most probable explanation for the results I gained; as mentioned
previously in my introduction, as light is one of the factors required
in order for photosynthesis to take place, as the intensity of the
light is increased, photosynthesis is able to take place at a higher
rate.

This is another concept to consider that we do not know all the "mechanisms" that drive it.
Basically photoinhibition is the damage to the light harvesting reactions of the photosynthetic capacity of a vascular plant, algae, or cyanobacterium by excess light energy trapped by the chloroplast.
This process can occur in in all organisms capable of oxygenic photosynthesis. In both plants & cyanobacteria, blue light causes photoinhibition more efficiently than other wavelengths of visible light, although it has been demonstrated the red light can cause photoinhibition as well.

Explanations

Reason 1

When the green plant is provided with a higher concentration of CO2 in
the environment it is photosynthesising in, the rate of photosynthesis
conducted by the plant will be higher - the availability of one of the
limiting factors was higher.

Factors affecting the rate of photosynthesis - Pass My …

This can be seen on the graph
as the highest point this is where the Elodea is photosynthesizing at
a high rate and it starts to slowly drop as the distance is
increasing.

FREE How does light affect the rate of photosynthesis …


My graph has no anomalies, and it closely followed to what I had
predicted that the closer the distance of the light the higher the
rate of photosynthesis would be and thus produce more bubbles in the
time recorded.

I plan to investigate how light intensity affects the rate ..

I can say that the
increase in distance thus making the light intensity stronger
increased the rate of photosynthesis and when further away made the
rate of photosynthesis almost come to its limiting factor the
straitening of the graph.

To investigate the effects of light intensity on photosynthesis.

Effectively this shows
that if more of these limiting factors can be used by a larger sample
compared to a smaller sample, then the rate or amount at which the
products of photosynthesis are given off will be at a higher level
too.
