I'm a bit confused by these sentences in my AQA A-level biology course:
The area of the graph [showing how the rate of PS increases compared to the light intensity] that curves is known as the light compensation point. This is the point at which the amount of CO2 used in photosynthesis is equal to the amount of CO2 produced in respiration.
Could someone explain this, please? Thanks!

Hi,
What specifically are you confused about? As I understand it but I'm struggling to find a way to reword it.

The amount of CO2 where? Produced by what, when?

The amount of CO2 produced by the plant in respiration is equal to the amount of CO2 being used by the plant in photosynthesis.

It's this bit mainly: This is the point at which the amount of CO2 used in photosynthesis is equal to the amount of CO2 produced in respiration.

As you know, cellular respiration produces CO2 in animals - plants are no different. When the amount of CO2 being used in photosynthesis equals the amount being produced by the plant's respiration, this is called the light compensation point.
At this point, the net CO2 assimilation is zero. You can see from this that the compensation point is likely to occur at two points in the day...

Oh I see! I guess I was just looking too far for an explanation, as usual haha. Thanks
