Auxanometer Diagram - Measuring Plant Growth in Science Education #1952466 (License: Personal Use)

This educational illustration depicts a mechanical auxanometer-a device that measures incremental growth in plants-attached to a young potted seedling. The instrument features a rotating arm with a calibrated arc (0-18 units), a counterweight, and a pointer indicating growth on the scale as the plant elongates. Designed for classroom use, it demonstrates quantitative plant biology principles in a clear, accessible way.

Used in K-12 and introductory college biology curricula to teach plant tropisms and growth measurement; supports lesson plans on experimental design and data collection in life sciences.
