Figure 14: Apples (A, B) are relatively acellular, with smooth cell walls and a glassy sheet-like, or plastic bag appearance. Bananas break into smaller rounded clumps that have rounded edges and varying sizes. Under MGG staining (C), the small clumps have a crumpled quality with an almost tacky texture. With PAP staining (D), banana particles become clear and thin. The fibrous strands that surround the banana fruit (the phloem bundles) can appear as jagged, fractured pieces admixed with the edible fruit’s thinner, smooth cells
