What is the rigid outer layer that surrounds plant cells?

• A. Cell Wall
• B. Cell Membrane
• C. Nucleus
• D. Cytoplasm

Answer: (A)

The main idea is what forms the rigid outer boundary of plant cells. The rigid outer layer around plant cells is the cell wall. It sits outside the cell membrane and is mostly made of cellulose, which gives plants their strength and shape. The cell wall protects the cell and helps it stay upright, and it also helps prevent bursting when water moves into the cell. The cell membrane, by contrast, is a flexible boundary that controls what enters and leaves the cell. The nucleus and cytoplasm are internal components, not the rigid outer shell.
