Cupule

Cupule is a term used in botany to refer to a type of structure found in certain plants. Specifically, it is a small, cup-shaped structure that typically houses or supports another structure, such as a seed or flower. The term is derived from the Latin word "cupula", which means "small cup".

Overview

In botany, a cupule is a structure that typically serves as a protective covering for another structure, such as a seed or flower. It is often found in plants that belong to the family Fagaceae, which includes oaks, beeches, and chestnuts. The cupule is a key characteristic of these plants, and it plays a crucial role in their reproduction and survival.

Structure and Function

The cupule is typically a small, cup-shaped structure that is formed from modified leaves or bracts. It serves to protect and support the seed or flower that it houses. In some plants, the cupule may also aid in the dispersal of seeds. For example, in the oak tree, the cupule (commonly known as an acorn cap) helps to protect the acorn and aids in its dispersal by wind or animals.

Examples

One of the most well-known examples of a cupule is the acorn cap of an oak tree. Other examples can be found in the beech tree, where the cupule encloses and protects the tree's nuts, and in the chestnut tree, where the cupule is spiny and helps to deter predators.
