Can you please help me with a simple and short answers please. Also no meed for explanation i just need answers.Thank you Anatomy of Eudicot and Monocot Roots Eudicot and monocot roots differ in the arrangement of their vascular tissue. Observation: Cross-Section Anatomy of Eudicot and Monocot Roots 1. Obtain a prepared cross-section slide of a buttercup (Ranunculus) root. Use both low power and high power 2. Locate the cortex, which consists of several layers of thin-walled cells (Fig. 19.6a, b). In Figure 19.6 3. Find the endodermis, a single layer of Eudicot Root to identify the epidermis (the outermost layer of small cells that gives rise to root hairs). The epidermis protects inner tissues and absorbs water and minerals. note the many stained starch grains in the cortex cells. The cortex is ground tissue that functions in food storage. cortex root hair cells whose walls are thickened by a layer strip. (It is as though these cells are glued endodermis together with a waxy glue.) Because of the Casparian strip, the only access to the xylem strip is through the living endodermal cells. The xylem ot-- endodermis regulates what materials that enter a plant through the root? water and phioem vascular roor? s thar pericycle Use this illustration to trace the path of water and minerals from the root hairs to 4. Identify the pericycle, a layer one or two cells thick just inside the endodermis. Branch roots originate from 5. Locate the xylem in the vascular cylinder of the root. Xylem has several "arms" that extend like the spokes 6. Find the phloem, located between the arms of the xylem. Phloem conducts organic nutrients from the xylem: this tissue. of a wheel. This tissue conducts water and minerals from the roots to the stem. leaves to the roots and other parts of the plant. Figure 19.6 Eudicot root cross section. The vascular cylinder of a dicot root contains the vascular tissue. Xylem is typicallty star-shaped, and phloem lies between the points of the star. a. Drawing. b.

Explanation / Answer
3a)Endodermis regulated the movement of water and minerals to enter a plant through root hairs.
b) The path of water and minerals from root hair to xylem - Root hair ---> cortex ---> Endodermis ---> pericycle ---> Xylem
The path through which water move into xylem cells of root occurs through both apoplast and symplast.
