2. Using page 6 of the tree book and the first page of the handout entitled "Tree Trunk Cross Section". (i.e. handout #1). Review the following terms: heartwood, sapwood, softwood, hardwood, vascular system, xylem ceils, phloem cells, cambium and bark. Fill in the blanks directly below. a. The heartwood is located in the of a tree cross section. b. The-?-of a tree contains both xylem and phloem cells. c. The sapwood of a tree is located?_(inside or outside) of the heartwood. 3. Locate the 2 "Ryker mounts" that contain tree sections. (The mounts are black frames with glass covers over the specimens). One is entitled "Woody Stem Tissue", the other "Hardwood vs. Softwood". After examining these mounts, fill in the answers to the corresponding true- false questions below d. Bark is comprised of both xylem and phloem cells. e. The terms heartwood and early wood refer to the same thing. f. "Hardwood" trees, i.e. those that flower, usually experience slower growth rates than "softwood" trees. g. The vascular cambium of a tree contributes to the newest layer both the xvlem and phloem cellsExplanation / Answer
2. (a) The heartwood is located in the center of tree cross section.
(b) The vascular system of tree contains both xylem and phloem cells.
(C) The sapwood of a tree is located outside of the heartwood.
3. (d). The bark is comprised of only phloem cells.
Hence the statement is (false).
(e). The earlywood or the springwood are made of living cells, whereas heartwood are made of dead cells.
Hence the statement is (false).
(f). Hardwood trees have slower growth rate as compared to softwood trees.
Hence the statement is (true).
(g). The vascular cambium provides the secondary new cells to both xylem and phloem tissue.
Hence the statement is (true).
