Now let's look at how water and minerals enter through the roots Roots are highly branched creating a lot of area for absorption Root hairs near each root tip increase the surface area water and minerals, shown in yellow can follow two paths from cell to cell within a route In one path, they travel in the cytoplasm which is connected between cells In the other path, they travel within cell walls In the path within cell walls however they encounter a waxy barrier that blocks entry to the xylum To continue, the water and minerals must cross a plasma membrane In this way, only certain minerals can enter the xylum
