Figure 17: The raspberry is a complex/composite fruit, with multiple berries attached together to form one raspberry unit. Stained with MGG (A), the flesh paucicellular and grungy shapes. With PAP stain (B), the cytoplasm is less viscous, and takes on a crumpled tissue paper-like quality. The strawberry is another composite fruit and the exterior seeds are consumed. The fragments of seeds are mixed into the fruit flesh, generating a granular background (C). At low magnification (D), the aggregate nature of the fruit is obvious, with cells attached onto a central core.
