STEM Flashcards
The area or region where leaves are attach
Nodes
The area or region between the nodes
Internodes
Occurs in the angle between the petiole and the stem
Bud
Bud located in the axil
Axillary bud
Open present at the tip of each twig
Terminal bud
Beard leaf like appendages at the base of the petiole
Stipules
Scar left by a fallen leaf
Leaf scar
That mark the location of the water conducting tissues located within the leaves cards
Bundle scars
Dark spots or elevations that allow gas exchange in the stem
Lenticels
What are the specialized stems
Rhizome
Tubers
Bulbs
Corm
Horizontal stem which grows near the surface of the soil
Rhizome
Enlarge ends of specialized underground branches
Tubers
Large bulbs with a small stem at the lower end surrounded by several flesh leaves
Bulbs
An underground stem which is short stout solid and more or less rounded in shape
Corm
Sub-aerial stem modification
Runner
Stolon
Offset
Sucker
A slender prostate branch with long or short internodes creeping on the ground and rooting at the nodes
Runner
Slender later branch originating from an underground stem and growing horizontally outwards
Stolon
Like the runners it originates in the axil of a leaf as a short more or less taken the horizontal branch
Offset
Like the stolen it is also a lateral branch developing from the underground part of the stem
Sucker
Thin leafless spiderly curve branch by which climbers attach themselves to other objects
Tendrils
Some stems maybe modified into hard street pointed structures called
Spines and thorns
In some plants stem are flattened and leaf like in appearance in the center of each is a node bearing very small scale like leaves with axillary buds
Cladophylls
In some plants stems are flattened stout and fleshy and are modified for water and food storage
Phylloclade
Enumerate the principal or main function of the stems
Mechanical support for leaves and other plant organs
Conduct water mineral salts and manufactured foods
