Conifers - Conifers are gymnosperms such as pine, hemlock and spruce and they do not have vessels. They have tracheids. There are two types of conifer wood: resinous and non-resinous. Conifer wood is made up mostly of tracheids and fiber tracheids, from a volume basis. Conifers have tracheids with pits. There are four basic types of wood, ring porous, diffuse porous, (simi-diffuse), conifer without resign ducts and conifers with resign ducts. And then there are palms.
