What type of grain do softwood trees have and why?

Softwood trees, such as pine and spruce, typically have a simpler grain structure compared to hardwoods. Their wood is characterized by straight, uniform grain patterns with fewer knots, which is largely due to the presence of tracheids—long, thin cells that facilitate water transport and provide structural support. This grain structure makes softwoods easier to work with and often less expensive than hardwoods, making them popular for construction and furniture.
