On the other hand, plants with more negative water potentials, such as -34.0 MPa, have lower soil water content percentages, such as 11.758 percent. Plants with more negative air potentials usually had higher soil water content, and plants with less negative air potentials had lower soil water content. It was also observed that plants in warmer environments had higher water potentials.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
