These dots are called achenes and are the true fruits of the strawberry plant. Each achene is really an individual fruit containing a single seed.

“According to bundle theory, an object consists of its properties and nothing more; thus, there cannot be an object without properties and one cannot conceive of such an object. For example, when we think of an apple, we think of its properties: redness, roundness, being a type of fruit, etc . There is nothing above and beyond these properties; the apple is nothing more than the collection of its properties. In particular, there is no substance in which the properties are inherent.”
