Plant Structure And Function

Front 1

Parechyma

Back 1

Soft,rounded cells with thin primary cell walls, air spaces between cells

Front 2

Collenchyma

Back 2

Strands of irregularly thickened primary cell wall, no air spaces, found particularly in young plants or new growth.

Front 3

Sclerenchyma

Back 3

Rigid secondary cell wall,may have no cyroplasm left

Front 4

Apical meristem

Back 4

Divides cells that form primary tissues, elongate to lengthen plant; found in stem buds and root tips.

Front 5

Primary growth

Back 5

Add brick at the top

Front 6

Secondary growth

Back 6

Add girth to sides. Eudicot plants (and gymnosperm) take on thickening,girth adding growth; trees, shrubs,vines.

Front 7

Intermediate growth

Back 7

Plants grow their whole life,as long as they have enough sources.

Front 8

Annual

Back 8

Life cycle is a single growing season

Front 9

Perennial

Back 9

Can live and reproduce for many seasons

Front 10

Wood

Back 10

Dead xylem tissue

Front 11

Vascualr cambium

Back 11

Growns from a meristem tissue. Divides primary xylem and phloem,add cells to the secondary growth

Front 12

Bark

Back 12

Growth that is to the vascualr cambium

Front 13

Heartwood

Back 13

Oldest layer of secondary xylem are in the center

Front 14

Sapwood

Back 14

Younger secondary xylem tissue that still conducts water

Front 15

Fertilizers

Back 15

Compund placed in the soil to enhance plant nutrition andencourage healthier growth

Front 16

Stromata

Back 16

Opening for a gas and water exchange;open and closed by guard cells.

Front 17

Transpiration

Back 17

The main method for water transport vertically

Front 18

Cohesive and adhesive

Back 18

No energy required, xylem sap is pulled upward bcoz of ____ and ____ properties of water

Front 19

Hormone

Back 19

Chemical signal that is transported to target cell and triggers their function or regulated timing of function

Front 20

Phototropism

Back 20

Directional growth towards light source

Front 21

Tropisms

Back 21

Directed growth response such as towards light or away from a barrier.

Front 22

Photoperiod

Back 22

Relative lengths of day and night that regulates plant's life cycle

Front 23

Part of stems

Back 23

Node,interlode,terminal bud, and axillary bud

Front 24

Node

Back 24

Point along the stem where leaves attach

Front 25

Interlode

Back 25

Space between leaves

Front 26

Terminal bud

Back 26

Tip of the stem, where height growth

Front 27

Axillary bud

Back 27

Side branches off stem;occurs between leaf and stem crook;gives birth to plant

Front 28

Primary site of photosynthesis

Back 28

Comprised of flat blade and petiole which attaches to stem.

Front 29

Simple leaf

Back 29

Single,individual blade,may have lobes or serrations

Front 30

Compund leaf

Back 30

Blade divided into many "leaflets"; main petiole grows off axillary bud,leaflets have no bud

Front 31

Doubly comfound leaf

Back 31

Leaflets divided into smaller leaflets

Front 32

Xylem

Back 32

Carries water

Front 33

Phloem

Back 33

Carries sugar solution

Front 34

Dermal tissues cover the plant

Back 34

Epidermis,stromata,bark

Front 35

Vascular tissues transports materials

Back 35

Xylem and phloem

Front 36

Ground tissues

Back 36

Metabolic functions, growth. Meristems,photosynthesis, storage)

Front 37

Organs

Back 37

Groups of tissue forming a larger structure, with a common structure and function.

Front 38

Shoot system

Back 38

Photosynthesis and reproduction

-stem with nodes

-leaves-axillary bud at base of each

Flower and fruits

Front 39

Root system

Back 39

Anchor plant; storage organs; arbsorption of water and nutrients

-roots,root hair
