Question 1 of 5

Time left: 00:00

Measurement or observation	Value
Cell solute potential	−0.80 MPa
Cell pressure potential	+0.30 MPa
Cell water potential	−0.50 MPa
External water potential	−0.20 MPa

Figure 1: evidence supplied for the question

A plant cell has solute potential −0.80 MPa and pressure potential +0.30 MPa. It is placed in a solution with water potential −0.20 MPa. What initially occurs?

Select one option.

Water enters because cell water potential is −0.50 MPa
Water leaves because cell water potential is +0.50 MPa
No net movement occurs
Solute actively diffuses out
The wall immediately lyses
