Solution:
- The cell membrane is composed of a phospholipid bilayer, which consists of two layers of phospholipid molecules with their hydrophilic (water-loving) heads facing outward and their hydrophobic (water-fearing) tails facing inward.
- In plants, the cell wall is composed primarily of cellulose, while in bacteria it can be composed of peptidoglycan or other materials. Fungi have cell walls composed of chitin.
