Question

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.

Calvin Cycle Photosystem I Photosystem II
Normal Sea Water GBR Sea Water



ATP 5.2 mM 0.1 mM
NADPH 5.3 mM 0.1 mM
Sugar 6.0 mM 0.2 mM
Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments.

Answer 2

Background

Explain the relationship between coral and algae, and how a problem with algae photosynthesis caused coral bleaching in the Great Barrier Reef. answer needs to be a 15 year olds wording

Answer 4

Experimental Data

Using the data from the paraquat experiment, explain how you know that paraquat did not cause the coral bleaching.​​​​​​​
