Question

How does the cell wall protect a plant cell?
The cell wall protects the cell by providing support and maintaining the cell's shape.
The cell wall protects the cell by storing food so the plant doesn't run out.
The cell wall is thin and flexible, which allows the cell to be moved without harming the organelles.
The cell wall is on the inside of the cell and serves to contain the contents of the cell.

Answer 1

Correct choice: "The cell wall protects the cell by providing support and maintaining the cell's shape."

Why:
- The plant cell wall (made mainly of cellulose, hemicellulose and pectin) is a rigid outer layer that gives structural support, helps maintain a fixed shape, and protects the cell from mechanical damage and excessive water uptake.

Why the others are incorrect:
- "Storing food": storage of nutrients is mainly done by the vacuole and other organelles, not the cell wall.
- "Thin and flexible": that describes the plasma membrane; the cell wall is generally rigid (though young walls can be more flexible).
- "On the inside... contain the contents": the cell wall is outside the plasma membrane; the plasma membrane contains the cell’s internal contents.
