Which of the following is considered a hard angiosperm (hardwood)?

Maple is classified as a hard angiosperm, commonly referred to as hardwood. Angiosperms are flowering plants that produce seeds enclosed within a fruit. Hardwoods generally come from broadleaf trees, characterized by their dense, sturdy wood. Maple trees belong to the family Sapindaceae and are known for their strong, durable wood, making it suitable for furniture, flooring, and musical instruments.

In contrast, the other choices—pine, cedar, and fir—are examples of softwoods, derived from coniferous trees. These trees have needle-like leaves and produce cones instead of flowers and fruits. Softwood is typically lighter and grows faster than hardwood, influencing its applications in construction and woodworking. The distinction between hardwood and softwood is primarily based on the type of tree, and the properties of the wood vary significantly between these two categories, emphasizing the unique characteristics that hardwoods like maple possess.
