A lattice is a structure made up of intersecting lines or bars that form a grid-like pattern. It is commonly used in various fields, including mathematics, physics, and engineering. In mathematics, a lattice can refer to a set of points in space that are arranged in a regular pattern, often used in geometry and number theory. In gardening and architecture, a lattice is often used as a decorative element or support for climbing plants. It provides a framework that allows plants like vines to grow upward while also adding visual interest to fences or walls. Lattices can be made from materials such as wood, metal, or plastic.
