Experts and non-expert groups do not categorize using the same levels. Suppose we compare horticulturalists to people with little knowledge about plants. If we asked the groups to name, as specifically as possible, five different plants seen around campus, we would predict that the expert group would primarily label plants on the level, while the non-expert group would primarily label plants on the level.

- Subordinate; basic.

Explanation:

As per the question, given that five different plants are there to be labelled; it could be predicted that the expert group would firstly label the plants on 'subordinate' level while the 'non-expert' group would label on the 'basic' level. The key reason for this difference is that the experts possess essential knowledge of the domain while the non-experts would move gradually towards the expertise. Thus, the former views the information in a distinctly organized and meaningful pattern significant to the aspects of their knowledge while the latter lacks in such aspects and views the given domain or situation differently.
