Choose the incorrect statement: a. Bundle sheath cells surround the vascular bundles in both eudicots and monocots. b. Phloem sieve elements contain a higher concentration of amino acids than xylem vessels. c. Phloem sieve elements and xylem tracheary elements are similar at maturity because they are both dead. d. Root hairs are the primary cell type that absorbs water in roots.

What is the term used to identify the multi-cellular ring of fibers surrounding each of the vascular bundles in a C3 leaf’s veination?   Select one: a. fiber sheath b. collenchyma collar c. turgor ring d. stomatal sheath e. granum circle

Which of the following is/are false regarding the phloem? A. It transports starch from the leaves to the stem. B. It transports sucrose from the leaves to the roots. C. It is located lateral to the xylem in tree stems. D. Unlike the xylem, majority of the cells are living. E. A and D F. B and C

Which of the following is false? a. Stems have vascular bundles, and roots have vascular cylinders. b. Lateral roots can arise from nodes on a root. c. Primary growth (lengthening) can occur at an axillary bud. d. Apical meristem gives rise to epidermal tissue, ground tissue, and vascular tissue. e. Wood is xylem that forms during secondary growth

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.
