Plant Xylem

An example of adhesion is

• Water molecules sticking to each other
• Water molecules sticking to cellulose in xylem walls
• Magnets sticking to a metal wall
• Gravity pulling water down

What is it called when water sticks to water?

• Cohesion

• Adhesion

• Capillary Action

• Xylem

When the forces of cohesion and adhesion work together, water can move up the plant against the force of gravity by....

• Phototropism

• Geotropism

• Photosynthesis

• Capillary Action

water movement through cellulose cell wall without entering protoplast of root cells is called

• symplast pathway

• vacuolar pathway

• apoplast pathway

• cellulose pathway

which theory of water transport states that hydrogen bonding allows water to maintain a continuous fluid column as water is pulled from roots to leaves

• Fusion

• Evaporation

• Pressure flow

• Cohesion-tension

Root pressure is caused by

• active loading of water molecules into xylem vessels by endordermis cells

• active loading of salts into xylem vessels by endodermis cells

• xylem vessels using energy to actively load water upwards

• movement of water molecules upwards in xylem vessels through osmosis

• Symplast

• Transpiration

• Evaporation

How does water enter a plant?
