What is one difference between the ways Aristotle and theophrastos classified plants?

Aristotle classified plants primarily based on their general characteristics and uses, focusing on their habitats and behaviors, such as whether they were herbs, shrubs, or trees. In contrast, Theophrastus, often considered the "father of botany," introduced a more systematic approach by categorizing plants based on their morphological features and reproductive structures, thus laying the groundwork for modern botanical taxonomy. This emphasis on detailed observation and classification in Theophrastus's work represents a significant advancement in the study of plants compared to Aristotle's broader classifications.
