what tissues do tracheids have
There are two types of cells that make up the xylem: tracheids and vessel elements. Both of these cell types are dead when they are used in the xylem. Using dead cells, which donât have organelles filling them up, allows more capacity for transporting water.Tracheids are long, narrow cells whose ends overlap.ylem and phloem make up the vascular tissue. The vascular tissue is arranged in bundles, and is easy to see in a cross-section of a stem: Another important tissue is the dermal tissue, which is the outer protective layer. Plants donât have skin exactly, but they do have an epidermis.
