features of a transport system

Question 1

lle mae xylem and phloem

Answer 1

xylem inside
phloem in the middle

Question 2

what is the vasuclar tissue fromed of

Answer 2

xylem and phloem

Question 3

what do the xylem and phloem form

Answer 3

vascular tissues

Question 4

2 functions of xlyem

Answer 4

transport of water and dissolved minerals
providing mechanical strenght + support

Question 5

what does xylem consist of

Answer 5

dead lignified tracheids and vessils

Question 6

what does xylem do

Answer 6

conduction or transport of water and salts

Question 7

how easy can water travel in xylem

Answer 7

easy - no barriers to stop flow

Question 8

what does vascular tissues provide in the stems

Answer 8

flexible support
resistance to bending strain

Question 9

what does vascular tissues provide in the leaves

Answer 9

arrangement of vascular tissues in the midrib and network of veins also gives flexible strength

Question 10

what does vascular tissues provide in the roots

Answer 10

helps the anchorage of the plant

Question 11

where is the greatest water uptake

Answer 11

root hair zone

Question 12

whats good about the root hair cell

Answer 12

surface area of the root is enormously increased by the presence of root hairs

freely permeablbe

Question 13

how can water travel? (3)

Answer 13

apoplast
symplast
vacuolar

Question 14

apoplast water movement

Answer 14

through the cell wall

Question 15

synplast water movement

Answer 15

through the cytoplasm and plasmodesmata

Question 16

vacuolar water movement

Answer 16

from vaculoe to vacuole

Question 17

whats the name of the dark strip which is waterproof in the plant cells thingies

Answer 17

casparian strip

Question 18

casparian strip thing about it

Answer 18

waterproof

because contains suberin

Question 19

what does casparian strip contain which makes it waterproof

Answer 19

suberin

Question 20

what does casparian strip do

Answer 20

water potential of endodermis cell raised by water being driven in by casparian strip

Question 21

what does the casparian strip actually do

Answer 21

prevents further transport through the apoplast

Question 22

what needs to happen for watee to travel past the casparian strip

Answer 22

water must enter the cell by osmosis
enter the symplast pathway

Question 23

what needs to happen for the water to move around the casparian strip

Answer 23

water potential in xylem must be much more negative than the water potential of the endodermal cells

Question 24

how is water potential of endodermis cells raised

Answer 24

by water being driven in by the Casparian Strip

Question 25

why is casparian strip essential

Answer 25

rehulate salt movement protect against entry of posions and fungal pathogens

Question 26

how are minerals taken up

Answer 26

by root hairs by active tranport moves through apoplast paethway and then through the transpiration steam ions enter cytoplasma and plasmodesmata through symplast pathway

Question 27

how are salts put into the vasuclar tissue

Answer 27

activley pumped this makes water potential of xylem more negative which causes water to enter the xylem by osmosis root pressure
