Bacteria enter susceptible plant tissues through

• A. Water
• B. Wounds and natural openings
• C. Pores
• D. Wind

Answer: (B)

Bacteria enter susceptible plant tissues through wounds and natural openings. Plants have a protective outer barrier, so pathogens need access points to invade. Wounds from physical damage, pruning, insect feeding, or weather create breaches that bacteria can exploit to enter and multiply. Natural openings such as stomata and other pores on the surface also serve as entry routes, especially when moisture films on the leaf surface allow bacteria to move into internal tissues. Water on the surface can help transport bacteria, but without a breach or opening, entry is limited. Wind may bring bacteria to the plant, but the actual entry still relies on a wound or natural opening. Hence, wounds and natural openings are the primary entry routes for bacterial pathogens.
