Answer:
B) cell wall and large vacuole
Explanation:
A plant cell has tough and rigid cell wall made of cellulose. Presence of cell wall imparts the plant cells a definite angular shape. The angular shape is also the result of presence of large vacuole in the center of the plant cell. The vacuole is filled with water and electrolytes and serve to determine the shape of the plant cell.
