biology

which is xylem and which is phloem

function of x y and z

• x = store food/carbohydrate, responsible for transportation of materials into central cylinder by diffusion

  y = protect the root, where root hair is attached, protective Barrier and protects against water loss

  z = regulates movement of water ion and hotmone

• x = regulates movement of water ion and hormone

  y = store food/carbohydrate, responsible for transportation of materials into central cylinder by diffusion

  z = protect the root, where root hair is attached, protective Barrier and protects against water loss

• x = protect the root, where root hair is attached, protective Barrier and protects against water loss

  y = regulates movement of water ion and hormone

  z = store food/carbohydrate, responsible for transportation of materials into central cylinder by diffusion

• None of the three

where does water move

• lower to lower water potential

• higher to higher water potential

• low to high water potential

• high to low water potential

where does water move in apoplast and symplast pathway

and how do they enter

• apoplast = water moves along cell wall by osmosis down water potential gradient

  symplast = water moves through plasmodesmata and enter by diffusion

• apoplast = water moves along cell wall and enters by diffusion

  symplast = water moves through plasmodesmata and enters by osmosis down water potential gradient

• apoplast = water moves through plasmodesmata and enter by diffusion

  symplast = water movesalong cell wall by osmosis down water potential gradient

• none of them

function of casparian strip and what it is made of

can water pass through lignin

• who knows

• no

• yes

• maybe

which is source and sink

what is source and sink

phloem loading ( accumulation of sugar/carbohydrate) will
