Question
Chapter 27, Problem 3CT
Summary Introduction
To explain: The reason why the roots lack the protective covering like the plant surface which has a waxy cuticle.
Concept introduction: Root is the plant part that typically lies below the soil surface. The root system is the extensive of the shoot system. The important function of the roots include taking up water (H2O) and mineral ions from the soil, anchor the plant to the soil, and store nutrients in some cases.

Aboveground plant surfaces are typically covered with cuticle. Why do roots lack this protective coating?
Why is it that the wall of the epidermis in the root area has no cuticle and has thin walls?
The mature regions of roots are relatively impermeable to water. Why? Explain its importance.

Endodermal cells constitute the innermost layer of root cortex and surrond the vascular cylinder (xylem and phloem). II. Endodermal wall is covered with waxy layer of casparian strip which blocks apoplastic transfer of minerals.III. Due to presence of casparian strip, water and minerals can only eneter the vascular cylinder if they will be able to cross the plasma membrane of an endodermal cell.arrow_forwardShow the sequence of secondary growth by drawing the row of cells from the boxed area below and labeling the vascular cambium cell (V), 5 xylem cells from oldest (X1) to youngest (X5), and 3 phloem cells (P1 to P3). Show what happens after growth continues by drawing and labeling a row with twice as many xylem and phloem cells. How does the vascular cambium’s location change? A pear has a hard texture but juicy.

- Secondary growth in stems involves two meristems. Identify and describe these two meristems, explain what tissues they are responsible for producing (including their functions), and explain the direction of cell division in which those tissues are produced in relation to the epidermis. For the last part of this question referring to the direction of cell division, make sure to address why cell division is occurring in two different planes. Also, as part of your answer, name and explain the functions of the tissues from the center of the stem to the dermal layer, in order, for a stem conducting secondary growth.arrow_forwardWhat is the function of the root hairs?
