Dentate

Dentate, in a biological context, describes an edge or margin that is characterized by tooth-like projections. These projections, often small and pointed, resemble teeth and can be found on various natural structures such as leaves, shells, and bones. The term highlights the presence of these "teeth," differing in size and sharpness. The arrangement and shape of these "teeth" can be used to identify various species of plants, animals, or other organisms. When applied to the appearance, it signifies a serrated or jagged outline, contrasting a smooth or rounded one.

Dentate meaning with examples

• The botanist carefully examined the leaf, noting the prominent dentate margin. He documented the shape and spacing of each 'tooth' for accurate species identification. The small teeth-like structures were clearly visible, distinguishing it from a similar species with a smooth edge. This dentate feature was key to differentiating the plant from others in its genus, and provided essential information for his research.
• Fossils of ancient marine creatures revealed dentate shells. Paleontologists studied the arrangement of these "teeth" along the shell's edge. The dentate structure of the shell hinted at its dietary habits and the types of predators that might have existed in its environment. Researchers found subtle variations in the dentate pattern which could suggest individual differences or even subspecies.
• Under high magnification, the microscopic image revealed the dentate edge of the insect's mandible. The sharp projections allowed the insect to effectively chew through tough plant matter. Examining the structure and arrangement of the dentate edge helped researchers understand how it functioned, allowing them to determine what the insect's diet consists of and where in the food chain it resides.
• The artist sketched the profile of the dinosaur bone, highlighting the dentate ridge. He emphasized the small teeth-like projections along the bone's surface, creating a visually striking illustration. The dentate edge added texture and suggested the bone's history. It enhanced the overall realism and communicated the form's structural integrity. The careful detailing gave the depiction a natural appearance.
• The ocean wave’s receding foam revealed a dentate pattern against the sandy shore. Each peak showed a sharp, irregular edge, like tiny teeth. The jagged shape formed along the water's edge displayed the effects of wind and currents. From the sky, the dentate shoreline created an interesting pattern. The way the waves crash against the shore give this dentate look.
