Definition
| modified stems: bulbs: vertical underground shoots made up of leaves that store food |
|
|
Term
|
Definition
modified stems: stolons: horizontal shoots that grow along the surface "runners"
they increase the surface are for photosynthesis |
|
|
Term
|
Definition

Specialized for ___
|
|
Definition
|
|
Term
Leaves:
Usually have two parts: |
|
Definition
|
|
Term
|
Definition
- "Stem" of the leaf
- Falls off stem when the leaf is shed
|
|
|
Term
|
Definition
- Flattened: increased surface area for photosynthesis

look for auxillary buds!! |
|
Definition
Site of a meristem = possible place where a new branch can grow
Located at the base of each petiole – not at the base of a leaflet |
|
|
Term
Apical meristem (at shoot apex)
[image] |
