Q1. A botanist notices necrotic spots on tobacco leaves. How does the Tobacco Mosaic Virus (TMV) typically spread from one infected plant cell to an adjacent healthy cell?
Answer: Plasmodesmata
Explanation: TMV spreads between adjacent plant cells through plasmodesmata. Stomata are for gas exchange and do not typically facilitate internal cell-to-cell viral spread.
