stems
|
supports the leaves and flowers of a plant; also used for transporting substances and for storing food
|
|
woody plants
|
plants that live several years and develop a large amount of wood in their stems
|
|
herbaceous plants, herbs
|
non-woody plants
|
|
vines
|
any plant with a long, thin stem that grows along the ground or has tendrils that twine around a wall or other support
|
|
taproot system
|
the primary root grows straight downs and remains larger than the secondary rootlets
|
|
fibrous root system
|
the primary root remains small and man slender secondary rootlets grow from it
|
|
vegetative reproduction
|
plant reproduction without flowers, seeds, or fruits'
|
|
root cap
|
the tip of the root which is made up of several layers of dead cells and new growth cells that form immediately behind the cap
|
|
cambium
|
a woody dicot has a layer of cells between its transport tubes
|
|
cambium cells
|
carry on cell division and make it possible for the root to grow in diameter
|
|
primary growth
|
growth in length
|
|
secondary growth
|
growth in diameter
|
|
root hairs
|
tiny hairs which develop from the sides of the root and forces their way between soil particles to absorb water and dissolved minerals
|
|
osmosis
|
the continuous movement of water from a solution of higher water content through a semipermeable membrane into a solution of lower water content
|
|
semipermeable membrane
|
a membrane that will allow some molecules to pass through but not others
|
|
cortex
|
the inner portion of the root which consists of storage cells surrounding the root's transport system
|
|
xylem tissue
|
carries water and nutrients from the root hairs upward through the root hairs upward through the root and stem to the leaves
|
|
the two types of vascular tissue which the plant's transport system consists of
|
xylem tissue and phloem tissue
|
|
phloem
|
carries glucose from the leaves back to the stem and roots
|
|
aids the rise of water through the xylem
|
capillary action and root pressure
|
|
root pressure
|
the upward force that results as water enters the roots by osmosis
|
|
capillary action
|
the tendency of water molecules to move up through the xylem tissue in response to surface tension
|
|
transpiration
|
evaporation from the leaves
|
