植物也能感受疼痛吗？

This is one of the most common challenges to veganism. The scientific consensus is clear: plants do not possess the neurological structures required for conscious pain experience. They lack a central nervous system, a brain, and nociceptors (pain receptors). While plants can respond to stimuli, this is fundamentally different from the subjective experience of suffering that animals possess.

Furthermore, even if one were to grant plants some form of sentience, the argument still supports veganism: animal agriculture requires vastly more plant crops (for feed) than direct human consumption of plants. Going vegan reduces total plant “deaths” as well.
