Chapter 7:Plant Transport

a hard material embedded in the cellulose matrix of the cell wall-proovides support so plan can grow upward

tranports water and minerals though vascular plants

tranports food through vascular plants

pointed ends, thick walls with pits that conect them to near by cells. water moves from cell to cell though these pits

wider,shorter,thinner walle and less tapered than tracheids.end walls are either missing or perforated

dissovled sugars move from areas of high pressure (source) to areas of lower pressure (sink)

water molecules are attracted to eachother and get pulled along

water molecules are attracted to polar molecules and get pulled along

le on either side of the sieve tubes

tiny pores in the walls at the ends .allows contents of cells to mix

water molecules being pulled along the capillaries by adhesion and cohesion
