Question: What determines the shape of fungal spores that are ejected into the air? Develop an hypothesis and suggest an experiment .
Background: Many fungi disperse their spores by ejecting them forcibly into the air.For spores to be picked up by the wind, however, they must escape a layer of still air called boundary layer that lies close to the ground. Escape from the boundary layer is easier if spores have a size and shape that minimizes drag, the resistance of air to the movement of the object.
