The first 2 min graph, was supposed to be ignored, the 2 lines of best fit were only up, and at 3, i don't remember exactly, maybe 35.9, I am not sure! wbu?

I don't remember exactly, somewhere between 110 and 12o though
oh thats nice. i know this isn't about chemistry but in biology paper 41 what did you answer for why algae photosynthesizes faster in polyp than when its free?

Its alright
I said that the coral respires producing co2, which is a raw material for photosynthesis. The CO2 is readily available for the algae to photosynthesise,while the free living algae, struggles to get CO2, as CO2 is sparingly soluble in water. This increases the rate of photosynthesis and therefore more growth
I wrote one more point that I completely forgot right now!!
What did you write?

i wrote that the surface area in the coral is greater than the free algae so there will be a greater uptake of CO2 and then the usual

But then how is the surface area greater, when its living inside its cells? I don't get your point :confused:

They were comparing the algae that lives in the coral, and the free algae
Not the coral and the free algae, plus corals are fish so they don't photosynthesise

i wasn't sure myself and was running out of time. But if they are fish they don't need algae to undergo photosynthesis for them to give food for growth?:confused:

They are fish, and the algae lives in their tissue. The algae does photosynthesis using co2 from the coral, and gives the coral the product of photosynthesis.
Get my point?

What subjects are you giving this session btw?

I guess. What did you get in AS bio overall? Sciences and math. What about you?
