Understanding Water Potential in Plants

What is the Greek letter used to represent water potential?

• Omega

• Alpha

• Beta

• Psi

How does solute concentration affect solute potential?

• Higher solute concentration makes solute potential more positive

• Higher solute concentration makes solute potential more negative

• Solute potential becomes zero with high solute concentration

• Solute concentration has no effect on solute potential

What is matric potential?

• The potential energy of water due to gravity

• The potential energy of water due to solute concentration

• The potential energy of water due to its attraction to surfaces

• The potential energy of water due to atmospheric pressure

In which type of plants does gravity significantly influence water potential?

• Aquatic plants

• Tall plants

• Small plants

• Desert plants

Through which processes can water move from areas of higher to lower water potential?

• Diffusion and precipitation

• Osmosis and transpiration

• Photosynthesis and respiration

• Evaporation and condensation
