Question
How does the presence of the tobacco mosaic virus affect the process of photosynthesis in infected plants?
Answer
The presence of the tobacco mosaic virus disrupts the normal structure of leaves, leading to a mosaic pattern of discolouration. This affects the chlorophyll content and reduces the leaf's surface area for photosynthesis, ultimately hindering the plant's growth and energy production.
Explanation
This answer is effective as it explains the mechanism by which the virus affects photosynthesis, linking the symptoms of the disease to its physiological consequences. The question assesses the student's ability to analyze the impact of a viral disease on a critical biological process.
Common mistake
Misunderstanding the Effects of Tobacco Mosaic Virus
Students often state that tobacco mosaic virus only affects the appearance of leaves without mentioning its impact on photosynthesis.
Emphasize that the virus not only causes a mosaic pattern of leaf discolouration but also significantly reduces photosynthesis and plant growth.
