Question

A. (HT only) temperature, light intensity, carbon dioxide concentration and chlorophyll can interact so that any one may limit photosynthesis.
B. Students often state that only one factor limits photosynthesis at a time, without considering the interaction between multiple factors.
C. It is not correct that (HT only) temperature, light intensity, carbon dioxide concentration and chlorophyll can interact so that any one may limit photosynthesis.
D. The idea only requires memorising the topic title for Photosynthesis.

Answer

In this question, (HT only) temperature, light intensity, carbon dioxide concentration and chlorophyll can interact so that any one may limit photosynthesis. is correct It stays aligned to the exact wording and meaning of the objective.

Explanation

In AQA-style practice, the correct answer must match the objective closely and use the science rather than filler wording. That is why (HT only) temperature, light intensity, carbon dioxide concentration and chlorophyll can interact so that any one may limit photosynthesis. is the best option here. Linking the idea to a condition that can restrict the rate of photosynthesis, such as temperature, light intensity, carbon dioxide concentration, or chlorophyll levels keeps the explanation specific.

Common mistake

Limiting Factors Interaction

Students often state that only one factor limits photosynthesis at a time, without considering the interaction between multiple factors.

Emphasize that temperature, light intensity, carbon dioxide concentration, and chlorophyll can interact, and any one of them may limit photosynthesis depending on the conditions.
