Palmate
Palmate (/pælˈmeɪt/; from Latin palmatus, "like a palm tree") is a term used in Botany and Zoology to describe certain types of characteristics that resemble the shape of a hand with fingers extended.
Etymology
The term "palmate" is derived from the Latin palmatus, meaning "like a palm tree". This is in reference to the shape of a palm leaf, which has lobes radiating from a common point, similar to the fingers of a hand.
In Botany
In Botany, palmate is used to describe the arrangement of leaflets or lobes in a leaf. A palmate leaf has lobes that are all attached at the same point at the base of the leaf, similar to the fingers of a hand. Examples of plants with palmate leaves include the Maple tree and the Horse chestnut tree.
In Zoology
In Zoology, palmate is used to describe certain types of animal features that resemble the shape of a hand with fingers extended. For example, the feet of many water birds and some mammals are described as palmate, as they have webbing between the toes that resembles the shape of a hand with fingers spread.
