32) Mitotic activity by the apical meristem of a root makes which of the following more possible? A) increased delivery of water to the aboveground stem B) decreased absorption of mineral nutrients C) increased absorption of carbon dioxide. D) effective lateral growth of the stem Answer: A Bloom's Taxonomy: Application/Analysis Section: 35.3 33) Which of the following root tissues gives rise to lateral roots? A) endodermis B) phloem C) epidermis D) pericycle Answer: D Bloom's Taxonomy: Knowledge/Comprehension Section: 35.3 34) As a youngster, you drive a nail in the trunk of a young tree that is 3 meters tall. The nail is about 1.5 meters from the ground. Fifteen years later, you return and discover that the tree has grown to a height of 30 meters. About how many meters above the ground is the nail? A) 0.5 B) 1.5 C) 3.0 D) 15.0 Answer: B Bloom's Taxonomy: Application/Analysis Section: 35.3 35) You find a plant unfamiliar to you and observe that it has vascular bundles scattered throughout the stem cross section. What do you conclude about the plant? A) It is probably an herbaceous eudicot. B) It will probably get annual rings of wood. C) It is probably a monocot. D) It could be either a young eudicot or a monocot. Answer: C Bloom's Taxonomy: Application/Analysis Section: 35.3 36) Monocot vascular bundles do not have a vascular cambium between the xylem and phloem. This means that monocots . A) are much less efficient at conducting water and sugars B) have very thin stems C) do not produce wood in annual rings D) cannot produce lateral shoots Answer: C Bloom's Taxonomy: Knowledge/Comprehension Section: 35.3 37) The following question is based on the drawings of root or stem cross sections shown in the figure. Refer to the figure. A monocot stem is represented by . A) I only B) II only C) III only D) IV only Answer: B Bloom's Taxonomy: Knowledge/Comprehension Section: 35.3 38) The following question is based on the drawings of root or stem cross sections shown in the figure. Refer to the figure. A woody eudicot is represented by . A) II only B) III only C) IV only D) I and III Answer: C Bloom's Taxonomy: Knowledge/Comprehension Section: 35.3 39) The following question is based on the drawings of root or stem cross sections shown in the figure. Refer to the figure. A plant that is at least three years old is represented by . A) I only B) II only C) III only D) IV only Answer: D Bloom's Taxonomy: Knowledge/Comprehension Section: 35.3 40) A student examining leaf cross sections under a microscope finds many loosely packed cells with relatively thin cell walls. The cells have numerous chloroplasts. What type of cells are they? A) parenchyma B) endodermis C) collenchyma D) sclerenchyma Answer: A Bloom's Taxonomy: Application/Analysis Section: 35.3 41) The veins of leaves are . I) composed of xylem and phloem II) continuous, with vascular bundles in the stem and roots III) finely branched to be in close contact with photosynthesizing cells A) only I B) only II
