Diagram and label a cross section of a primary eudicot root. Identify the function of three of the

labeled tissues. What will be an ideal response?


The diagram should resemble an amalgamation of Figs. 36-3 and 36-4. The functions of tissues to
choose from are as follows:epidermis
: absorption of water and minerals
cortex: the bulk of the cortex is involved in storage
endodermis: regulates the flow of water and minerals into xylem
pericycle: site of lateral root formation
xylem: transport of water and minerals
phloem: transport of dissolved sugars
