|
DETAILS ABOUT MONOCOTS
|
-no true pith

|
no vascular bundle arrangements
|
|
|
What is the arrangement of vascular bundles within a HERBACEOUS DICOT stem
|
in a ring formation
|
|
|
What is the arrangement of tissues within a vascular bundle in a WOODY DICOT
|
phloem on outside
xylem on inside |
|
|
What is the arrangement of tissues within a vascular bundle in a HERBACEOUS DICOT
|
phloem=outside
xylem=inside vascular cambium between them |
|
|
What is the cause of secondary growth in a HERBACEOUS DICOT
|
vascular cambium
|
|
|
What is the cause of secondary growth in a WOODY DICOT
|
vascular cambium, cork cambium
|
|
|
examples of plants-HERBACEOUS
|
roses, violets, sunflowers
|
|
|
examples of plants-WOODY
|
maple tree
|
|
|
interesting details-WOODY
|
xylem- 2 colors
-lighter color is spring wood |
|
|
interesting details-HERBACEOUS
|
has a pith (symmetrical middle)
|
|
|
Stolon definition and example
|
Stolon (or runner) horizontal above-ground stems (generally) often
forming roots and/or plantlets at their tips or nodes …can be one of several “stems” of the plant ex: (strawberry runners, spider plants) |
|
|
tuber definition and example
|
enlarged rhizome containing stored food
ex: Tuber enlarged rhizome containing stored food (Irish potato- the eyes of the potato are the modified buds.) |
|
|
rhizomes definition and example
|
Rhizome horizontal underground stem, typically forms roots and plantlets at tips or nodes …the main stem of the plant
ex: Iris |
|
|
corms definition and example
|
Corm a swollen, underground, compressed stem base
used for propagation, bud on top, used by some plants for food storage to survive drought/harsh winters ex: crocus |
|
|
bulbs definition and example
|
Bulb thickened, underground stem with fleshy storage
leaves attached at base ex: onion, tulip |
|
|
Which part of xylem on a woody dicot stem is nearest the centre of the tree?
|
the oldest
|
|
|
Compare the appearance of a herbaceous monocot to a herbaceous dicot stem
|
The herbaceous monocot stem differs from a herbaceous dicot because the herbaceous monocot does not have a pith. Also, the dicot has vascular bundles in a ring formation. They both have phloem on the outside and xylem on the inside.
|
|
|
Describe the appearance of summer wood and its location
|
Summer wood is darker in colour because it has a higher density and because it has stopped growing. The summer wood is located within a woody dicot stem nearest to the centre of the tree.
|
|
|
What is the role of meristematic tissue and where can you find it in the stem?
|
Meristematic tissue has cells that are constantly dividing, which leads to plant growth and expand the plant with the aid of water. Meristematic tissue is found in the cork cambium and the vascular cambium.
|
|
|
How does a monocot stem get larger?
|
A monocot stem gets larger due to meristematic tissue
|
|
|
What is collenchyma and where an you find it?
|
Collenchyma is a type of cell that is living, dividing and non growing. It has thin walls that are flexible and allow the stem to bend. It can be found within ground tissue and within dermal tissue.
