Question

1. describe the appearance of the vacuole in a well - watered plant. what effect would this have on the cell wall of the plant? the cell wall provides support and protection while the cellular membrane controls substance movement. 25. using your response to question 24, construct an explanation for why a plant has both a rigid cell wall and a cellular membrane.

Explanation:

In a well - watered plant, the vacuole is large and filled with water, creating turgor pressure. This pressure pushes against the cell wall, making it firm. The cell wall provides structural support and protection from mechanical damage and pathogens. The cellular membrane is semi - permeable and controls the movement of substances in and out of the cell. A plant has both a rigid cell wall and a cellular membrane because the cell wall offers support and protection for the overall structure, while the membrane regulates the internal environment and substance exchange at the cellular level.

Answer:

1. In a well - watered plant, the vacuole is large and filled with water, exerting turgor pressure on the cell wall, making the cell firm.
2. A plant has a rigid cell wall for overall structural support and protection from external damage and pathogens. It has a cellular membrane to control the movement of substances in and out of the cell, regulating the cell's internal environment.
