参考答案: Greenhouses have controlled environments/the plants can be grown in the most suitable environment for the fastest growth. Investigations can be carried out for particular crops to find out the optimal conditions for photosynthesis. Optimal photosynthesis rate gives maximum growth of the crop. (2 marks maximum)
The limiting factors that can be controlled/whose effect on photosynthesis can be minimised include: Carbon enrichment, the increase in carbon dioxide in the atmosphere of the greenhouse.
The light intensity by lighting the greenhouse.
Optimal temperature of the greenhouse for enzyme function. (2 marks maximum)
