Chapter 24: Quiz

Identify this plant as a monocot or eudicot after examining its stem and leaf. A) This plant is a monocot. B) This plant is a dicot. C) Not enough information is provided to differentiate the plant as a monocot or dicot.

A) This plant is a monocot.

Which of the following tissues forms the outer protective covering of the plant? A) epidermal tissue B) ground tissue C) meristematic tissue D) vascular tissue

A) epidermal tissue

To prepare a microscope slide of mitosis, where would one most likely find examples of cell division in a plant? A) near the root tip B) in a tree trunk, near the center C) anywhere in the mesophyll of a leaf D) at the center of a root, back from the tip

A) near the root tip

Which of these plant tissue types is composed of hollow nonliving tracheids and vessel elements that transport water and nutrient minerals from the roots to the leaves? A) xylem B) phloem C) collenchyma D) sclerenchyma E) parenchyma

A) xylem

All of the following are specialized epidermal cells except A) root hairs. B) trichomes. C) collenchyma. D) guard cells.

C) collenchyma.

The meristems that arise from the apical meristem include all of the following EXCEPT A) protoderm. B) ground meristem. C) epidermis. D) procambrium.

C) epidermis.

Considering that leaf stoma have the conflicting functions of allowing gaseous carbon dioxide into the leaf, yet preserving the plant's supply of water, which of the following is (are) reasonable? A) A submerged-water plant would have no stoma. B) Tree leaves that orient flat and present the top side to the sun would have most of their stoma on the bottom of the leaf. C) Corn, oats, rice, and wheat-all monocots-have relative upright blades with sunlight hitting both sides and would have stoma distributed evenly on both sides. D) All of the choices are reasonable. E) None of the choices is reasonable, since stoma are found uniformly on all type of leaves.

D) All of the choices are reasonable.

Consider the possibility that we discover a gene that regulates both the amount of root hairs and where root hairs grow on a root tip. Since the surface area provided by root hairs is so critical to their uptake of water and nutrients, expanding their growth area seems a great advantage. However, which of these might be a problem? A) Growth of root hairs in the zone of cell division would interfere with root cell proliferation. B) Growth of root hairs in the root cap would cause them to be shredded off since this area takes substantial abrasion. C) Growth of root hairs in the zone of elongation would cause them to be shredded off as they anchored in soil and the root lengthened. D) All of these choices pose a problem.

D) All of these choices pose a problem.

Which of the following tissues transports water and nutrients within the plant? A) epidermal tissue B) ground tissue C) meristematic tissue D) vascular tissue

D) vascular tissue

Which statement about leaves is NOT correct? A) The epidermis is covered by a waxy layer of cuticle that reduces water loss. B) Gas exchange occurs through tiny openings in the leaf surface called stomates. C) Regulation of gas exchange through the leaf is the responsibility of the guard cells. D) Vascular tissue is arranged in a net pattern in dicots and a parallel pattern in monocots. E) In eudicots, the photosynthetic mesophyll is made up of an upper spongy layer and a lower palisade layer.

E) In eudicots, the photosynthetic mesophyll is made up of an upper spongy layer and a lower palisade layer.

Which of these plant tissue types most closely corresponds to the "typical" unspecialized plant cell? A) xylem B) phloem C) collenchyma D) sclerenchyma E) parenchyma

E) parenchyma

Identify the incorrect pairing of tissue type with cell type. A) Ground tissue - Collenchyma cells B) Epidermal tissue - Parenchyma cells C) Vascular tissue - Xylem D) Epidermal tissue - cuticle

B) Epidermal tissue - Parenchyma cells

B) celery.

Which of the following structures is an underground horizontal stem? A) bulb B) rhizome C) corm D) stolon

B) rhizome

Which of these vascular tissue cells is alive but lacks a nucleus? A) tracheid B) sieve-tube members C) vessel element D) companion cell

B) sieve-tube members
