Which three organelles work together to prevent a plant cell from bursting when it has absorbed too much water?
a
vacuole, cell wall, and cell membrane
b
cytoplasm, cell wall, and endoplasmic reticulum
c
ribosome, cell membrane, and Golgi apparatus
d
lysosome, cell membrane, and chloroplast
a) vacuole, cell wall, and cell membrane
The correct answer is: a) vacuole, cell wall, and cell membrane.
The correct answer is a) vacuole, cell wall, and cell membrane.
Explanation:
When a plant cell absorbs too much water, it can lead to excessive swelling and the risk of bursting. However, plant cells have specific mechanisms to prevent this from happening. Three organelles work together in this process:
1. Vacuole: The vacuole in a plant cell acts as a storage space for water and other substances. When excess water enters the cell, the vacuole absorbs and stores it, keeping the water content controlled.
2. Cell Wall: The cell wall surrounds the cell membrane in plant cells. It provides structural support and rigidity to the cell. The cell wall is made up of a tough, fibrous substance called cellulose, which helps to keep the shape of the cell intact, even when it takes in large amounts of water.
3. Cell Membrane: The cell membrane is a selectively permeable barrier that surrounds the plant cell. It controls the movement of substances in and out of the cell. When a plant cell absorbs too much water, the cell membrane prevents further intake of water, helping to maintain the balance and preventing bursting.
Therefore, the correct answer is the combination of vacuole, cell wall, and cell membrane (option a).
