Which device allows germinating plants to be attached and rotated?

The clinostat is a device specifically designed to allow germinating plants to be attached and rotated, which is essential for their growth in microgravity or as a part of a controlled experimental setup. By rotating the plants, the clinostat helps to simulate a more uniform gravitational effect, which is particularly useful in studying plant growth behaviors and responses.

This rotation promotes even distribution of growth hormones, which can be affected by gravity. While other devices listed may serve distinct roles in plant cultivation—such as providing light or aeration—they do not have the specific function of rotating the plants. The phototron focuses on maximizing light exposure for plants, the germinator is primarily used for starting seeds under optimal conditions, and the aerogarden utilizes hydroponics for plant growth without soil, but none replicate the clinostat's ability to rotate for uniform growth response studies.
