Flashcards in 10/20 Plant Anatomy Deck (63):
1

plants organized in what?

hierarchy

2

root is the same as what in a human?

heart

3

tissue is the same as what in a human?

muscle tissue

4

organs

composed of several types of tissues that carry out a particular function.

5

tissue

composed of a group of cells with a common function and structure

6

what are the three basic plant organs?

roots, stems and leaves

7

shoot system needs....

water and minerals

8

root system needs....

photosynthetic products from shoot sys

9

monocots

have one cotyledon

10

dicots

have two cotyledon

11

what are the 3 types of tissues?

dermal, vascular and ground

12

dermal tissue fx?

protects against dehydration, insects, animals, and pathogens

13

epidermis

one single layer

14

waxy coating on leaves and stems

cuticle

15

fx of cuticle

prevent dehydration and pathogens

16

stomata

tiny openings on leafs that allows plants to breathe

17

vascular tissue transport materials between what?

leafs and roots (photosynthetic products)

18

xylem

transports water and dissolves minerals

19

phloem

transport organic nutrients (sugars)

20

cell wall

made up of cellulose

21

chloroplast

photosynthesis

22

central vacuole

filled up with water (firmness) makes up cell rigid

23

root

have vascular tissue in the center (pith)

24

Stem

have vascular tissue in the edges "ring" (cortex)

25

plant cells have 3 unique parts

chloroplast, the sites of photosynthesis, central vacuole

26

Parenchyma

alive(Y), 1cellwall(Y), 2cellwall(N), fx photosynthesis, storage, metabolic process

27

Collenchyma

alive(Y), 1CW(Y), 2CW(N), fx flexible support, elongate, "string of celery"

28

Sclerenchyma

alive(N), 1CW(Y), 2CW(Y), fx support

29

secondary cell wall location

inside

30

primary cell wall

outside

31

xylem (water conducting cells)

alive(N), 1CW(Y), 2CW(Y), fx support and water transport (diff, xylem wider and tracheids thinner opening)

32

tracheids (water conducting cells)

alive(N), 1CW(Y), 2CW(Y), fx support water tansport (similarities openings for water transport)

33

sieve tube members (sugar conducting cell)

alive(Y), 1CW(Y), 2CW(N), fx transport sugar

34

companion cell (sugar conducting cell)

alive(Y), 1CW(Y), 2CW(N), fx transport and production of proteins

35

taproot

carrot, radishes, potato

36

does not have a endodermis

stem

37

potato eye

axillary buds

38

cactus spine and not leafs

too much sun, too much surface area, less water loss

39

roots fx

anchors plant in the soil, absorb&transport minerals and water, stores food

40

monocot roots

thin roots spread out shallowly in the soil

41

dicot root

have one main vertical taproot with many small secondary lateral roots growing outward

42

root hair

is an extension of an epidermal cell

43

ex of prop roots

corn

44

ex aerial roots

orchids

45

ex of climbing roots

ivy

46

ex of aquatic roots

water hyacinth

47

ex sucker root

mistletoe

48

ex food storage root

carrot

49

why would farmers harvest carrots, beets or sweet potatoes befor plant's flower (veggie)

make the flower sweeter

50

stem fx

support the leaves and flowers

51

green stem fx

perform photosynthesis

52

what are buds?

undeveloped shoots

53

stolons or runners

grow horizontal along the ground surface, reproduce asexually

54

rhizomes fx

store food and have buds, they spread and form new plants

55

peeling onion is removing what?

leaves attached to a short stem

56

leaves

photosynthesis, composed of lamina (blade) and petiole (stalk)

57

types of leaves

simple leaf, and compound leaf

58

simple leaf

one blade per leaf, has bud by stem

59

compound leaf

many distinct blade per leaf, no bud but has bud wher the rachins meet the stem (branch)

60

epidermis covered by waxy coat?

cuticle and prevents water loss but also prevents gas exchange

61

trichomes

leaves covered with hairs, fx catch water, reduce airflow and produce wax

62

palisade mesophyll

tightly packed cells on the upper surface

63

spongy mesophyll

loosely arranged cells
