1. What is the primary structural component (fungi)?Chitin, a polymer of N-acetylglucosamine
2. What is a cell wall and why do plants need it?A cell wall is a tough outer layer that surrounds the cell membrane, giving the plant its shape and protecting it from damage. It also stops too much water from flooding the cell.
3. How do plant cell walls stay strong?Plant cell walls are made mainly of cellulose fibers, plus other sugars and sometimes lignin, which together form a rigid but flexible material that holds the cell up.

Osmotic Lysis: The rupture of a cell due to excessive water uptake and internal pressure.
Turgor Pressure: The hydrostatic pressure exerted by the cell contents against the cell wall.
Peptidoglycan Synthesis Inhibitors: Antibiotics that block the formation of bacterial cell walls, leading to cell death.
