Q

epidermal tissue

A
  • from rotoderm
  • contain closely packed epidermal cells
    • contain waxy cuticle, 1 layer
  • roots contain root hairs
  • lower leaf surface contain stomata
  • woody plants covered by cork
  • trichomes (Pubescence=plant hair)
20
Q

Ground tissue

A

forms bulk of a plant (from Ground meristern)
parenchyma cells
collenchyma cells
sclerenchyma cells

21
Q

parenchyma cells

A

least specialized, all organs of plant, divides

22
Q

collenchyma cells

A

thicker primary walls, bundles under epidermis

23
Q

sclerenchyma cells

A

thick secondary walls with lignin, nonliving, support/protection

24
Q

vascular tissues

A 
from procambium (vascular bundles) 
includes xylem and phloem
25
Q

xylem

A

transports water and minerals from the roots to the leaves (against gravity), Dead

26
Q

Phloem

A

transports sucrose and other organic compounds from the leaves to the roots (up, down, laterally), Living

27
Q

Root Organization

A 
root apical meristem (RAM)
primary meristem
zone of maturation
epidermis root hairs
cortex
endodermis
vascular tissue
28
Q

Root diversity

A

primary root
fibrous root system
adventitious roots

29
Q

primary

A

Fleshy, long single root that grows straight down; Stores food; lateral roots

30
Q

fibrous

A

Slender roots and lateral branches; Anchors plant to soil

31
Q

adventitious

A

Above ground, develop from shoot system; Anchor and increase water flow

32
Q

Stem Organization

A

Shoot Apical Meristem

33
Q

Shoot Apical Meristem

A

produces new cells that elongate

protected by terminal bud

enveloped by leaf primordia

specialized by primary meristems

34
Q

meristems

A

protoderm
ground meristem
procambium

35
Q

Woody stems

A

both primary and secondary tissues

have no vascular bundles, but instead have 3 regions
bark
wood
pith

36
Q

primary tissues

A

formed each year from primary meristems

37
Q

secondary tissues

A

develop during first and subsequent years from lateral meristems

38
Q

stolons

A

Above-ground horizontal stems

Produce new plants when nodes touch the ground

39
Q

Rhizomes

A

Underground horizontal stems

Contribute to asexual reproduction

40
Q

Rhizomes variations

A

tubers

corms

41
Q

tubers

A

enlarged portions for food storage

42
Q

corms

A

underground stems that produce new plants during next season

43
Q

leaf blade

A

facilitates collection of solar E

- thinness prevents overheating

44
Q

leaves adapted to

A

environment

45
Q

roles in

A

attachment
attraction
protection
