1. (3 pts) Describe the chemical structure of the plant cell wall and plant cell membrane. Make sure to include whether each structure is hydrophobic or hydrophilic. The plant cell wall contains cellulose and the membrane contains phospholipids. Cellulose is hydrophilic‚ meaning that it likes and is attracted to water. The phospholipid bilayer that makes up the cell membrane is both hydrophilic and hydrophobic. It contains hydrophilic heads that face the outside of the bilayer‚ and hydrophobic
