Quick student answer
How do you explain tobacco mosaic virus causes a mosaic pattern of leaf discolouration that reduces photosynthesis and plant growth?
Direct answer
In Biology, this page helps you answer questions about tobacco mosaic virus causes a mosaic pattern of leaf discolouration that reduces photosynthesis and plant growth within Communicable diseases. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are tobacco mosaic virus and photosynthesis reduction.
Key terms
- tobacco mosaic virus: A widespread plant pathogen that causes a mosaic pattern of leaf discolouration, reducing photosynthesis and plant growth.
- photosynthesis reduction: The decrease in the process by which plants convert light energy into chemical energy, often due to diseases like tobacco mosaic virus.
Common trap
Misunderstanding the Effects of Tobacco Mosaic Virus: Emphasize that the virus not only causes a mosaic pattern of leaf discolouration but also significantly reduces photosynthesis and plant growth.
