Controlled Environment Agriculture: Glasshouses & Polytunnels
Test: Protected crop growing (glasshouses and polytunnels)
20 questions
Question 1: Boosting light intensity in polytunnels exclusively through artificial lighting does not contribute to extra production in plants from photosynthesis.
A. Yes
B. No
Explanation: Artificial lighting can be used to boost the intensity of light in a polytunnel, which leads to extra production in the plant from photosynthesis.
Question 2: A raised temperature inside a polytunnel increases the rate of enzyme reactions, including those in photosynthesis, thereby increasing plant growth.
A. Yes
B. No
Explanation: The study materials state that the effect of a raised temperature inside a polytunnel is to increase the rate of enzyme reactions, including those in photosynthesis, which consequently increases the rate of plant growth.
Question 3: Maintaining excessively high humidity levels inside polytunnels is a recommended practice to prevent the spread of diseases.
A. Yes
B. No
Explanation: The study materials state that 'Care must be taken to ensure humidity of the air is not too high as this could encourage spread of diseases, caused by fungi and bacteria.' This indicates that high humidity levels actually promote disease spread, rather than preventing it.
Question 4: Polytunnels enable growers to achieve increased crop yields.
A. Yes
B. No
Explanation: The protection offered by polytunnels allows growers to achieve increased crop yields.
Question 5: A raised temperature inside a polytunnel primarily reduces the rate of enzyme reactions, including those in photosynthesis.
A. Yes
B. No
Explanation: The study materials state that the effect of a raised temperature is to increase the rate of enzyme reactions, including those in photosynthesis, which hence increases the rate of growth of the plants, not primarily reduce it.
