Conifers are a group of trees and shrubs that belong to the class Pinopsida. They are characterized by their needle-like leaves and cones, which contain seeds. Common examples of conifers include pine, spruce, and fir trees. These plants are primarily found in temperate and boreal forests around the world and are known for their ability to thrive in various climates. Conifers are evergreen, meaning they retain their leaves throughout the year, providing year-round greenery. They play a crucial role in their ecosystems by providing habitat and food for wildlife. Additionally, conifers are important for the timber industry, as their wood is used for construction, paper, and furniture.
