Movement of water through a plant and evaporation

from leaves, stems and flowers is Translation.

• True

• False

Water molecules attracted to each other to move up the plant.

• Cohesion

• Transpiration

• Adhesion

• Capillary Action

• Root Pressure

HOW IS WATER TRANSPORTED UP THE PLANT?

• Cohesion

• Translation

• Adhesion

• Capillary Action

• Root Pressure

Minerals are actively moved (takes energy)

into the root cells and Osmotic pressure increases in the cell which begins to force water upwards

• Cohesion

• Translation

• Adhesion

• Capillary Action

• Root Pressure

Capillary Action... (check all that apply)

• takes place because of adhesion of water molecules and walls of xylem

• Transpiration is the evaporation of water vapour from plant

  leaves via the stomata

• walls are closer together and water and dissolved minerals move up the xylem

• water is POLAR, the water molecules in the xylem are connected by COHESIVE FORCES

• root pressure (in roots) and capillary action (in stem) allow water and minerals to go up

Label "A"

• Leaf - evaporation from stomata

• Water potential gradient

• Xylem - cohesion & adhesion

• Roots - Osmosis into root hairs

• None of the above

Label "C"

• Leaf - evaporation from stomata

• Water potential gradient

• Xylem - cohesion & adhesion

• Roots - Osmosis into root hairs

• None of the above

The process of transporting sugar and other organic

materials through the phloem of the plant is Translocation.

• True

• False

What is happening at " 1 "

• Sugar is actively loaded into phloem tubes at the source.

• Water flows into phloem passively, down its concentration gradient, increasing the water pressure.

• Sugar moves into sink cell.

• Water flows out of the phloem tube passively, down its concentration gradient, decreasing the water pressure.

What is happening at " 3 "

• Sugar is actively loaded into phloem tubes at the source.

• Water flows into phloem passively, down its concentration gradient, increasing the water pressure.

• Sugar moves into sink cell.

• Water flows out of the phloem tube passively, down its concentration gradient, decreasing the water pressure.
