review questions

1. name two structures that are found only in plant cells.

Explanation:

1. The cell wall is the stiff outer - layer of plant cells, surrounding the cell membrane and its contents. It's composed of non - living cellulose, limits growth and movement, and gives the plant its shape.
2. Cellulose is a non - living material as stated in the text about cell walls.
3. From the table, chloroplasts and cell walls are structures found only in plant cells.

Answer:

1. The cell wall is the stiff outer layer of plant cells, surrounding the cell membrane and its contents. It is composed of a non - living material called cellulose. Its stiffness limits the plant's growth and movement and gives the plant its shape.
