Question

which symptom is best described as progressive death from the tip of the branch downward?
wilting
dieback
distortion
discoloration

Explanation:

• Wilting: Refers to the loss of rigidity in plant tissues due to water loss, not a progressive death from the tip of the branch downward.
• Dieback: This term specifically describes the progressive death of plant tissue starting from the tip of a branch and moving downward.
• Distortion: Involves abnormal changes in the shape of plant parts (e.g., leaves, stems), not a form of tissue death.
• Discoloration: Relates to changes in the color of plant tissues (e.g., yellowing, browning), but not the described pattern of progressive death.

Answer:

Dieback
