Dead cells that provide inelastic support in ground tissue. Answer to Xylem includes all of these excepta. Cells with tapering end walls. Vessels are elongated dead cells found in the xylem of flowering plants, consisting of perforated cell walls throughout which the water flows. tracheids.d. cells that story starch and carry out photosynthesis and respirations. Pits of tracheids consist of a pit membrane and the torus in a center, there are no openings. Their main function is water and mineral transportation. 9. Secondary cell wall is thicker than vessels. Tracheids are _____ (living/dead) cells _____ (with/without) protoplast. Xylem is a complex tissue which consists of dead cells called xylem vessels and tracheids. Tracheids are usually considered to be primitive cells. They have a thick lignified wall and lack protoplasm. Tracheids are shorter cells (about 1 mm long) They are imperforated cells. I will mark the best answer as the brainlist Vessels are found only in angiosperms. Which type of tissue forms the inner lining of … Vessels are only found in Angiosperms. Sclerenchyma, in plants, support tissue composed of any of various kinds of hard woody cells. Vessels are vertically aligned tubes made up of dead cells that transport liquid. Which one is made of dead cells ? Parenchyma. Mature sclerenchyma cells are usually dead and have thick secondary cell walls. Tracheids, vessel members and fibers are dead cells. Secondary cell wall is thinner than tracheids. Vessels (in hardwoods) and tracheids (in conifers) conduct water and substances dissolved in water. 10: Vessel elements are connected in an end to end fashion.
