B4 Plant Transport

Question 1

Water

Answer 1

.from roots to leaves (for photosynthesis and cooling)

Question 2

Minerals

Answer 2

.from the soil (for growth and making proteins)

Question 3

Sugars

Answer 3

.from leaves to other parts (for energy and storage)

Question 4

Xylem Vessels

Answer 4

Transport water and minerals ions from roots to leaves
Direction- one way only-upward
Structure- long- hollow tubes made of dead cells with thick walls
Support- help support the plant ( like straws)

Question 5

Transpiration - water loss in leaves

Answer 5

Transpiration = loss of water vapor from the leaves
Water evaporates from leaf surface - more water pulled up from roots
Light intensity - Stomata open - more water lost
Wind - blows away water vapor - faster Transpiration
Humidity - Dry air - faster water loss

Question 6

Phloem - Sugar Transport

Answer 6

Phloem tubes - Transport sugars (glucose) made in leaves
Direction- both directors - up and down
Structure- made of living cells with sieve plates
Process - called transaction ( moving Sugar’s around the plant)

Question 7

Sugars go to.

Answer 7

.growing parts (for energy)
.roots (for storage and starch)

Question 8

Stomata and Guard Cells

Answer 8

.stomata = Tiny holes on underside of leaves
.guard cells open and close Stomata to control water loss and gas exchange.

Question 9

What happens when stomata opens?

Answer 9

(Stomata) when open:
.water can evaporate (transpiration)
.Carbon dioxide can enter for photosynthesis
