Answer 1

Answer:

Water moves from areas of where water potential is higher (or less negative), to areas where it is lower (or more negative), and we refer to this movement as osmosis. ... Water potential is what allows water to get into plant roots when there is more solute within the root

Answer 2

Answer:

$\large\red\{Water potential (Ψ) is actually determined by taking into account two factors - osmotic (or solute) potential (ΨS) and pressure potential (ΨP). The formula for calculating water potential is Ψ = ΨS + ΨP. Osmotic potential is directly proportional to the solute concentration.}$
