Identify the false statement The phloem can bidirectionally transport material. While the xylem can only unidirectionally transport material. The xylem is responsible for the transport of water while the phloem is responsible for transporting nutrients. Water moves from root to leaf through capillary action. The phloem is made up of dead cells and the xylem is made up of living cells.

QUESTION 14 Which of the following comparisons of xylem and phloem is FALSE? Xylem is dead when it is functional, but phloem cells are living. Primary xylem and phloem cells originate in the procambium. In vascular bundles, xylem cells are generally larger in diameter than phloem cells. Xylem cells are separated from phloem cells in roots, with xylem in a bundle on the inside of the root and phloem in a ring around the root exterior. QUESTION 15 Where would you find endodermis cells with the waxy Casparian strip? surrounding the vascular bundle at the center of a root on the exterior of the plant stems and leaves inside the vascular bundle at the center of a root surrounding the vascular bundles in stems

Which of the following is a correct statement about the ascent of water in the xylem? The creation of new cells in the apical meristem creates a new water demand in the shoot, forcing the plant to transport water upwards. Living cells of the xylem provide the main conduit for an ascent of water. Water moves from a region with high pressure to a region with low pressure. The evaporation of water from leaf mesophyll cells generates tension in the water column.

2 Give the technical terms for the following: The category of plant tissues that have lost their ability to multiply The kind of plant cells with thin walls and usually a single large vacuole (iii) Elongated cells which are thickened at the corners (iv) The two types of tissues which provide the upward movement of water and dissolved materials from the roots to other parts of the plant. 3 Mention if the following statements are true (T) or false (i) Phloem cells carry manufactured food from leaves to other parts. (ii) Veins of leaves have both xylem and phloem. (iii) The older xylem tissue does not participate in transport. (iv) The sclerenchyma consists of actively dividing cells.
