'Der Botaniker' (botanist) belongs to a word family. 'Die Botanik' (botany) is the scientific field, and 'botanisch' (botanical) is the related adjective.
Sie studiert Botanik an der Universität.

The ending '-iker' often refers to a male person with a scientific or technical profession. This pattern is also found in words like 'Physiker' (physicist), 'Chemiker' (chemist), or 'Informatiker' (computer scientist).

As a job title, 'Botaniker' (botanist) is often used with verbs such as 'arbeiten als' (to work as) or 'sein' (to be). People also speak of a 'Team von Botanikern' (team of botanists) or a 'berühmten Botaniker' (famous botanist).

gardener
'Gärtner' and 'Botaniker' both have to do with plants, but in very different roles. A 'Gärtner' (gardener) works practically with gardens, soil, and plants, for example planting, cutting, and caring for them. A 'Botaniker' (botanist) studies plants scientifically and examines them. Learners may confuse the words because both can know a lot about plants. If someone works in a garden, 'Gärtner' fits. If someone researches plants or describes them scientifically, 'Botaniker' fits.

The botanist investigates in the laboratory why this plant grows so quickly.
Im Park schneidet der Gärtner die Hecken und pflanzt neue Blumen.
