WHAT IS :. Tissues are groups of cells that work together to perform a specific function. These cells are often similar in structure and are organized into layers or masses..

Xylem. Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. Together, xylem and phloem make up the plant's vascular system, which is responsible for the transport of water, nutrients, and sugars throughout the plant..

Xylem is composed of several types of cells, including: Tracheids: Elongated cells with tapered ends. They are found in the xylem of all vascular plants. Vessel Elements: Shorter, wider cells that, when arranged end to end, form vessels. Vessel elements are found in angiosperms (flowering plants) and some gymnosperms (non-flowering seed plants). Xylem Fibers: These cells provide additional support to the xylem. Xylem Parenchyma: These are living cells that play a role in the storage and metabolism of various substances within the xylem..
