Palmate

Palmate describes a hand-shaped structure, typically used in botany and zoology. It refers to something radiating outwards from a central point, resembling the palm of a hand with fingers. In botany, it's most often used to describe leaves, lobes, or veins that spread from a single point at the base. In zoology, it can describe structures like the webbed feet of certain birds or amphibians. The term highlights a multi-lobed or digitated form, distinct from other leaf or appendage arrangements. This characteristic signifies an adaptation for various purposes, such as gathering sunlight, navigating aquatic environments, or providing structural support.

Palmate meaning with examples

• The maple tree's leaves displayed a classic palmate form, with five distinct lobes radiating outward. The vibrant green color in the spring indicated the leaves' efficient use of photosynthesis as the branches provided shade to the forest below. The beauty of this tree is a favorite among many.
• Examining the duck's foot, we observed a clearly palmate structure, well-suited for propulsion in water. Each webbed toe aided in efficient movement while swimming and diving. This adaptation demonstrates the bird’s natural selection for its aquatic environment, increasing its chance of survival in the open water.
• The botanist carefully documented the palmate venation of the grape leaf, noting the arrangement's efficiency. The veins converged at the base of the leaf blade, distributing nutrients throughout the leaf. The leaf showed signs of slight damage by an insect, but nothing to worry about.
• The giant water lily, with its enormous palmate leaves, created a floating platform on the pond's surface. Its large, round shape was extremely unique for it's environment. Sunlight was able to shine through the water and help nourish the lily's root.
• The intricate palmate pattern of the starfish's arms allowed for effective locomotion and gripping the seabed. Each arm was used to search the ocean floor for prey, and to navigate in the low visibility ocean bottom. These creatures are very interesting to learn about.
