Plants Flashcards
what do plant cells require in order to grow
turgor pressure
what is the major structural component of cell wall
cellulose
what are the two compartments the cell wall creates
apoplast and symplast
three major plant tissues
vascular, dermal, ground
what is the vascular tissue
vessels; transport things around (xylem and phloem)
what is the dermal tissue
outer layer of the plant
what is the ground tissue
everything else inside plant
if a plant has vascular bundles scattered throughout the stem is it a monocot or a eudicot
a monocot has its vascular bundles scattered throughout
what moves water and minerals in plants
xylem
what controls stomatal aperture
xylem
what 2 cells make up the xylem
tracheas and vessels elements
is the xylem under positive or negative pressure
negative pressure; water is being sucked up
how is water able to be pulled up
cohesion by hydrogen bonding
what is the cause of tension in the xylem fluid
transpiration at the leaf surface
is the connection in the xylem fluid through cohesive or adhesive forces
cohesive forces
what is the purpose of root hairs
increase surface area for absorption
what does the stomata control
controls the transpiration stream
what is stomata aperture regulated by
light, aba, and k+ & water movement between guard and surrounding cells, primary via aquaporings
