Plant Experiment in Space

An astronaut floats in a space station laboratory holding a clear container with a small plant, beside a microscope and an Earth-view window. Look for the plant’s leaves and roots, the row of test tubes and the many cupboard doors. The plant can stand out against the straight lines of the equipment.
