Bio 102- Chapter 24

Front 1

Above ground part, stems, leaves and flowers. Framework for upright growth.

Back 1

The shoot system

Front 2

Below ground parts. Absorb water and nutrients, anchor,storage of photosynthetic products

Back 2

The root system

Front 3

Three processes involved in growth

Back 3

Cell division
Cell elongation
Cell differentiation

Front 4

Only occurs at the meristems

Back 4

cell division

Front 5

Activity here results in primary growth. A plant only lengthens here.

Back 5

Apical Meristem

Front 6

Activity here results in secondary growth. A thickening of older roots and shoots. Vascular cambium. cork cambium.

Back 6

Lateral Meristem

Front 7

Most common type of tissue. Composes most of the soft plant parts. Metabolically active and living.

Back 7

Parenchyma.

Front 8

Structural support for soft, non-woody plant organs. Living tissue. Elongated cells. does not interfere with growth. "Strings" of celery.

Back 8

Collenchyma

Front 9

Strong support for plant parts. Thick, lignified cell walls. Dead at maturity.

Back 9

Sclerenchyma

Front 10

Long, tapered cells

Back 10

Fibers

Front 11

Stubbier cells

Back 11

Sclereids

Front 12

Conducts water and dissolved minerals. Dead at maturity.

Back 12

Xylem

Front 13

Transports sugars. Living tissue.

Back 13

Phloem

Front 14

Covers and protects plant surfaces.

Back 14

Epidermis

Front 15

Three plant tissue systems.

Back 15

The ground tissue system
The vascular tissue system
The dermal tissue system

Front 16

apical dominance. Main zone of primary growth.

Back 16

Terminal buds

Front 17

Dormant shoots. Forms in a leaf axil

Back 17

Lateral buds

Front 18

veins are netlike

Back 18

Dicots

Front 19

Veins are parallel

Back 19

Monocots

Front 20

Outermost layer

Back 20

Epidermis

Front 21

Root cortex is below the epidermis for:

Back 21

storage

Front 22

Inner layer of cortex. controls water flow in the vascular tissues

Back 22

endodermis

Front 23

Vascular cylinder.

Back 23

Stele

Front 24

outer-most layer of stele. Gives rise to lateral roots.

Back 24

pericycle

Front 25

Ground tissue. not in dicot roots.

Back 25

pith

Front 26

Secondary xylem

Back 26

Wood

Front 27

Secondary phloem

Back 27

Inner bark

Front 28

Results from growth in the vascular cambium . concentric rings of secondary xylem. alternating bands of early and late wood.

Back 28

annual rings

Front 29

spring. pail and less dense

Back 29

early wood

Front 30

autumn, darker, more dense.

Back 30

Late wood.
