Chapter 31 Pt 2

Question 1

The green tissue in the interior of a leaf; a leaf’s ground tissue system; the main site of photosynthesis.

Answer 1

Mesophyll

Question 2

Flowering plants whose embryos have a single seed leaf, or cotyledon.

Answer 2

Monocot

Question 3

The point of attachment of a leaf on a stem.

Answer 3

Node

Question 4

In plants, a relatively unspecialized cell with a thin primary wall and no secondary wall; functions in photosynthesis, food storage, and aerobic respiration and may differentiate into other cell types.

Answer 4

Parenchyma cells

Question 5

A plant that lives for many years.

Answer 5

Perennial

Question 6

The portion of a plant’s vascular tissue system that conveys sap throughout a plant. This structure’s tissue is made up of sieve-tube members.

Answer 6

Phloem

Question 7

Part of the reproductive organ of an angiosperm, a single carpel or a group of fused carpels.

Answer 7

Pistil

Question 8

Part of the ground tissue system of a dicot plant. This structure fills the center of a stem and may store food.

Answer 8

Pith

Question 9

An increase in the length of a plant root or shoot, produced by an apical meristem.

Answer 9

Primary Growth

Question 10

horizontal stem that grows below the ground.

Answer 10

Rhizome

Question 11

An outgrowth of an epidermal cell on this structure, which increases this structure’s absorptive surface area.

Answer 11

Root Hair

Question 12

A structure, which anchors it in the soil, absorbs and transport minerals and water, and stores food.

Answer 12

Root System

Question 13

Light-colored, water-conducting secondary xylem in a tree

Answer 13

Sapwood

Question 14

In plants, a very hard, dead sclerenchyma cell found in nutshells and seed coats; a stone cell.

Answer 14

Sclereid

Question 15

A food-conducting cell in a plant. Chains of this structure’s members make up phloem tissue.

Answer 15

Sieve Tube Member

Question 16

A pore surrounded by guard cells in the epidermis of a leaf. When these structures are open, CO2 enters a leaf, and water and O2 exit. A plant conserves water when its stomata are closed.

Answer 16

Stoma

Question 17

Embryonic tissue at the tip of a shoot, made up of developing leaves and a compact series of nodes and internodes.

Answer 17

Terminal bud

Question 18

A tapered, porous, water-conducting and supportive cell in plants. Chains of this structure or vessel elements make up the water-conducting, supportive tubes in xylem.

Answer 18

Tracheid

Question 19

An enlargement at the end of a rhizome in which food is stored.

Answer 19

Tuber

Question 20

A strand of vascular tissues (both xylem and phloem) in a plant stem.

Answer 20

Vascular bundle

Question 21

During secondary growth of a plant, the cylinder of meristematic cells, surrounding the xylem and pith, that produces secondary xylem and phloem.

Answer 21

Vascular Cambium

Question 22

A short, open-ended, water-conducting and supportive cell in plants. Chains of this structure or tracheids make up the water-conducting, supportive tubes in xylem

Answer 22

Vessel element

Question 23

Secondary xylem of a plant

Answer 23

Wood

Question 24

The nonliving portion of a plant’s vascular system that provides support and conveys sap from the roots to the rest of the plant. This substance is made up of vessel elements and/or tracheids, water-conducting cells. The primary version of this substance is derived from the procambium. The secondary version of this substance is derived from the vascular cambium in plants exhibiting secondary growth.

Answer 24

Xylem
