Conifers are a group of trees and shrubs that belong to the class Pinopsida. They are characterized by their needle-like leaves and the production of cones, which contain seeds. Common examples of conifers include pine, spruce, and fir trees. These plants are primarily found in temperate and boreal regions, where they thrive in various climates. Conifers are important for the environment as they provide habitat for wildlife and play a crucial role in carbon sequestration. Their wood is widely used in construction and paper production. Additionally, conifers are often used in landscaping and as Christmas trees, making them significant in both ecological and economic contexts.
