### plant part | stem | twig:

Infected twig
* become swollen, distorted, and if girdled can die.
* exude creamy bacterial ooze in droplets or fine, hair-like strands.
* serve as important sources of inoculum.
* tend to die easily.

Infested twig
* are very subject to wind breakage.
* break off in the wind.

Twig blight
* can continue to infect fruit-bearing twigs at all stages of development.
* causes death and browning of twigs tips
  - the stems of plants to die and can result in reduced fruit production
* is blight

### plant part:

Stolon
* Most stolons produce plants
  - require sunlight
* Some stolons have creep growth habits
* are above ground runners, while rhizomes are under ground runners
  - above-ground stems that spread horizontally for vegetative reproduction
* are flat, smooth, usually bent and root at the nodes
  - widely branched and root at each node
  - hairy and creeping
  - horizontal stems that grow above the soil surface
  - nesessary for the exchange of nutritions
  - similar to runners
  - weak stems that root readily, assuring rapid colonization
* arise from the base of the plant.
* connecting parent and daughter plants usually die off in fall.
* develop at least by the time the fifth leaf emerges
  - basally
  - above-ground and form nodes which give rise to new plants
  - aboveground such as on strawberries, and are also called runners
* grow from the leaf axils during the summer to produce new rosettes
  - in spring and summer and growth peaks in late summer
* includes sections.
* often remain green.
* plant organ
  - part
* produce a thick, dense turf that supports moderate traffic
* root at the nodes to form new rosettes that are genetically identical to the parent.

Stroma
* Some stromas contain enzymes.
* are plant tissue.
* is animal tissue

  - prepared in the late dormant season immediately before buds swell
  - safety and aesthetic concerns
  - stubs
  - susceptible for several weeks after cutting
* bring in a lot of unwanted soil and gravel.
* can be massive in a big tree
  - destroy outdrives, outboard and boat hulls
* natural object
* plant part.
* produce a very vigorous growth.
* rooted carrot does well in poor garden soil.

### plant part:

Tendril
* Some tendrils are leaves or stipules, others are modified stems
  - arise from stems
  - can respond to contact quite rapidly, in only a few minutes
  - emerge from seeds
  - grow on stems
* Some tendrils have adhesive pads
  - peas
  - provide sustenance
* appear every third leaf oppositely are reddish in color and used for growth along surfaces.
* are always modified leaves or leaflets
  - common in vines and used for support
  - long and simple
* are slim, flexible leafless stems that wrap around structures
  - shoots or, in some cases, leaf-like parts that act as tendrils
  - flexible, leafless stems that wrap themselves around anything they contact
  - usually modified leaves, branching like the veins of a normal leaf
* develop in the base of leaf petioles.
* look like string.
