Plant Cells Flashcards
phloem
type of tissue that transports sugars made in the leaves to other parts of a plant
translocation
transport of materials, such as water and glucose, in plants
xylem vessels
pipelines for the flow of water up plants.
lignin
a hard substance in the walls of dead xylem cells that make up the tubes carrying water up plant stems
stomata
small openings mainly on the lower surface of leaves
transpiration stream
movement of water through a plant as a result of loss of water from the leaves
vascular bundles
groups of xylem and phloem vessels within plant stems
transpiration
loss of water from plant leaves through their stomata
guard cells
cells on either side of a stoma that work together to control the opening and closing of the stoma
wilt
droop//Plant stems and leaves wilt when there is insufficient water in their cells.
vacuoles
sacs within a cell used to store food and wastes
flaccid
describes cells that are not firm due to loss of water
