1

annual plant

live and die within a year

2

perennial plant

live for many years

3

2 types of perennial plants

deciduos and evergreen

4

deciduous

loose leaves in fall

5

three types of plant tissues

epidermal, ground, and vascular

6

transport is provided by _ tissue

vascular

7

protection is provided by _ tissue

epidermal

8

support & storage is provided by _ tissue

ground

9

periderm

outer layer of tissue on roots and stems

10

root epidermis

acidic cells on periderm

11

stem epidermis

cork aka bark

12

leaves epidermal tissue

secretes waxy cuticle

13

why do leaves have waxy cuticle?

protects froms dehydration and repels water

14

plant body consist mostly of _ tissues

ground

15

parenchyma

ground tissue used for juice and starch storage

16

collenchyma

ground tissue that provides flexible support

17

sclerenchyma

ground tissue that provides firm support

18

types of vascular tissues

xylem and phloem

19

what is the xylem

vascular tissue that performs water transport from roots to leaves

20

what is the phloem

vascular tissue that performs sugar transport from leaves to rest of plant

21

where does primary plant growth occur

stem and root tips

22

primary growth occurs lengthwise or diameter-wise

lengthwise

23

what root cells contribute to primary plant growth

root meristem cells

24

what stem cells contribute to primary plant growth

apical meristem cells

25

define secondary plant growth

diameter-wise growth - occurs in woody perennials

26

what tissue is responsible for secondary plant growth

cambian tissue

27

where is Vascular Cambium located

between phloem and xylem

28

where is Cork, or Bark, Cambium located

between bark and cortex tissue, cortex is the photosynthesizing tissue

29

leaf blade

leaf body

30

leaf veins

transport vessels

31

leaf petiole

attaches leaf blade to stem

32

where on leaf are stomata located?

epidermis

33

what are stomata housed with on leaf epidermis

guard cells

34

what are stoma used for on leaf

gas exchange

35

types of internal leaf tissues

Palisade Mesophyll cells, ground tissues, Spongy Mesophyll Cells, Vascular Tissues

36

internal leaf ground tissue

2 layers of photosynthesizing cells in leaf

37

Palisade Mesophyll Cells

tightly packed cells located on top of leaf

38

Spongy Mesophyll Cells

not as tightly packed as Palisade, located on bottom of leaf

39

internal leaf vascular tissues

located in leaf veins, consist of xylem and phloem

40

internal leaf tissue xylem

used for water transport from roots

41

internal leaf tissue phloem

used to transport sugars throughout plant

42

monocot stem structures

pith, vascular tissue, epidermis

43

monocot stem epidermis

green leafy covering of stem

44

monocot stem pith

ground tissue that stores starch

45

monocot stem vascular tissue

stem Xylem and Phloem

46

annual eudicot stem epidermis

green outer covering of stem

47

annual eudicot stem pith

ground tissue that stores starch

48
