Final answer:
The statement is false because a plant dying from exposure to poison is an example of a chemical change, as it involves a change in the plant's chemical composition, not just a physical alteration.
Step-by-step explanation:
The question: A plant dying after being exposed to poison represents a physical change, true or false?. False. This statement is false because a plant dying from poison represents a chemical change, not a physical one. This is due to the alteration of the chemical structure within the plant as a result of the poison, which causes damage or death to the plant. For instance, when a toxic agent like poison interacts with a plant's biological systems, it can lead to a series of biochemical reactions that ultimately cause the plant cells to die, a process that involves a change in the chemical composition of the plant.
Additionally, the terms chlorotic (yellowing of leaves due to lack of chlorophyll) and necrotic (dead tissue) refer to conditions that are symptomatic of underlying chemical changes within the plant tissues. Therefore, exposure to poison and the resulting damage is a clear example of a chemical change.
