Chapter 9
diffusion
low-high is against gradient
equilibrium
move along with concentration gradient
rate of diffusion depends on
temp
density of the medium
pressure
higher concentration to lower concentration
osmosis
diffusion of water through semipermeable membrane
high concentration to low concentration
turgid cell
firm cell due to water gained by osmosis
osmotic pressure
stops osmosis
primary way water enters plants
pressure
pressure potential
turgor pressure
water entering cell
pressure develops against walls
pressure-flow hypothesis specifics
water potential
turgor pressure
phloem loading
food substances
mass flow
water diffuses back to xylem
osmotic pressure
pressure required to prevent osmosis
balanced by resistance of call wall
pressure-flow hypothesis
water enters through osmosis
move along concentration gradients
nutrients
macronutrients
used by plants in greater amounts
when any required element is deficient in soil
micronutrients
used by plants in very small amounts
plants exhibit characteristic symptoms
