6. Which method does water used to move betwen plant cells?
- Active transport
- Diffusuion
- Osmosis
- Facilitated Diffusion
7. Where is the xylem usually found in the stem?
- In between two major vessels
- Nearest the pith
- Nearest the parenchyma
8. What is not an adaptation of a xerophyte?
- Thick waxy cuticle
- No stomata
- Hinge cells
- Hairs on surface of leaf to trap moist air
- Smaller leaves
- Densley packed spongey mesophyll
- Stomata in Pits
- Closing stomata
9. What is not an adaptation of a sieve tube element?
- No nucleus, tonoplast or ribosomes
- End walls break down to form a continnuous pipe
- Sieve plates at intervals
- Contain very little cytoplasm
- Near a companion cell
10. What is not an adaptation of a xylem cell?
- End walls break down to form a continnuous pipe
- Sieve plates between the elements
- Pits allow lateral movement
- Long thick walls with lignin in it to waterproof
11. Why do plants have transport systems?
- To send leafmail to each other
- Impatient and Rash
- Large and multicellular
- Large SA:V
12. What is transpiration?
- Loss of water vapur from ariel ports of a plantdue to evaporation
- Movement of a stream of water from the highest point of a mountain to the sea
13. What do sieve plates not have?
- Is between sieveplates
- Many plasmodesmata between compaion cells to allow comunication
- Pores to allow entry to ions
- Dense cytoplasm
14. What is not used to make the transpiration stream work ?
- Active transport
- Cohesion using hydrogen bonds between the water molecules
- Activley transporting ions into the stem to lower PSI
- Pressure from the water molecules make sit move up
- Adhesion using hydrogen bonds between walls of xylem and water
- Movement through apoplast or symplast pathway
15. The apoplast pathway goes through..?
- The cell walls
- Plasmodesmata in the cytoplasm
