16
Q

What does the xylem do?

A

Transports water and minerals from the soil to the leaves; made of dead cells (tracheids or vessel elements)

17
Q

What does the phloem do?

A

Transports glucose and sugars formed during photosynthesis; made of living cells (sleeve tubes)

18
Q

How does water enter the roots?

A

Osmosis from the soil to the xylem

19
Q

How are minerals transported into the xylem?

A

Facilitated diffusion

20
Q

What is the mixture of water and minerals called?

21
Q

Water molecules, because of their shape and polar nature, are attracted to one another, what is this called?

22
Q

The water molecule are also attracted to the walls of the xylem which is called?

23
Q

What two factors allow water to move against gravity?

A

Root pressure and Transpiration

24
Q

What does root pressure do?

A

It pushes; as H2O moves into the roots it causes an increase in pressure, as pressure builds it forces water up the xylem

25
What does transpiration do?
It pulls; as H2O exits the leaf by transpiration the cohesive attraction pulls xylem sap up to replace the lost water
26
What cells produce sugars that provide energy for the whole plant?
The palisade cells and spongy cells
27
How is sugar pumped into the phloem?
Active transport
28
As the sugar concentration in the phloem increases, what will happen ?
Water will move in by osmosis
29
As water moves in what increases?
Turgor pressure
30
When turgor pressure rises what will happen to the phloem?
It will move through pores into neighbouring cells
