Root hair

Epidermal cell that increase surface area

6

Velamen tissue

Velamen tissue are root used to absorb moisture from arieal part

7

Bud

Under developed compact shoott
Terminal/ apical bud:: tip, growth of stem and branches
Axillary bud: leaf angle is axil

8

Stem modification

1 underground stem
2 stem tendrils
3 thorn

Tuber: potato,
Corm: cccga
Bulb: onion, garlic, Lily

10

Corm

Cccga
Colocasia, colchicum. Corcus, gladiolus, amorphaphallus

11

12

Sub aerial weak

Offset: (P.E) Pistia, eichhornia (short internode)
Sucker: pineapple, banana, Chrysanthemum( viroids)
Runners: grass, oxalis (long internode)
Stolons: jasmine, mint

13

Aerial

Arid region
Flattened stem- opuntia, fleshy- euphorbia [PHYLLOCLADE]
Unlimited growth

14

Cladode
1 internode

Stem is Leaf structure, asparagus, ruscus

15

2 lateral small leaf

18

Venation

Arrangements of vien and vienlets in the lamina or leafblade
Reticullate: DICOTS, peepal, hibiscus, luffa
Parallel: MONOCOT, banana

19

Compound leafs
RACHIS

Pinnately compound: have rachis, midrib eg- Neem
Plamately: eg- silk cotton

Phallode

Petiole to flat leaf for photosynthesis eg: Austrian acacia

23

Inflorescence

Arrangements of flower in floral axil

Racemose:
Grow indefinitely
ACROPETAL SUCCESSION
Old at base
Eg: Radish, Lupin, Mustard

Cymos:
Stops
BASIPETAL
New at base
Eg: Begonia, team, (BAkUGo), solanum, dianthus

24

Thalamus

Swollen end of stalk or pedical

25

4 whorls

Calyx, corolla, androecium, gynocim
In Lily, calyx and corolla are not diff, hence called PERIANTH
