Document Summary

Root anatomy: the outside of the root is epidermis this is a single layer of tissue and is what covers the root. 1. inner layer of cortex: a single layer of cells a) the endodermis has very tightly fitted cells. 1. this is where the xylem and the phloem are located: mycorrhizae (fungi) 2. indirectly increases surface area of roots to increase the absorption of water and minerals this association between fungi and plants is a key aspect to why land plants are able to colonize the land. The uptake of water and minerals which is occurring by the roots: water potential, abbreviated by the greek letter psi ( ) 2. free energy of water a) refers to the amount of energy available to do work. Long-distance transport bulk flow: diffusion explains movement of water over small, cellular scales, refers to the movement of liquid in response to a pressure gradient.
