A biologist specializing in botany.

Botany studies plants: their structure, physiology, genetics, reproduction, evolution and interactions with other organisms. A question such as how a plant survives drought connects several scales: guard cells regulate water loss, xylem transports water, and inherited variation changes performance across environments.

Botany combines observations of natural diversity with experiments on defined mechanisms. Comparing root pressure with water flow during transpiration, for example, distinguishes a positive pressure generated below from a pulling force associated with evaporation above.
