Quizplus · Accepted Answer

Ethylene is unique among plant hormones because it is a gas. This means that its effects are not limited to the site where it is produced, but can spread to other parts of the plant through the air. It also means that its concentration can be difficult to control, as it depends on factors such as temperature and air circulation.
