Does plant cells that are placed in water will not burst due to the resistance of cellulose?
Yes, that is correct. The cell wall of a plant cell is made up of cellulose, which provides strength and rigidity to the cell. When plant cells are placed in water, they undergo a process known as turgor pressure, in which the water enters the cell and pushes the cell membrane against the cell wall. However, the cellulose cell wall prevents the cell from bursting, allowing it to maintain its shape and function properly.
When plant cells are placed in water, they do not burst due to the resistance of cellulose. Here's a step-by-step explanation:
1. Cellulose is a complex carbohydrate that is a major component of the cell walls of plant cells.
2. The cell wall provides support and strength to the cell and helps maintain its shape.
3. Plant cells have a high concentration of solutes, such as various ions and organic molecules, inside their cytoplasm.
4. When a plant cell is placed in water, there is a difference in solute concentration between the inside of the cell and the outside environment.
5. As a result, water molecules move into the cell through a process called osmosis, from an area of lower solute concentration (outside) to an area of higher solute concentration (inside).
6. As water enters the cell, the cell membrane pushes against the cell wall due to the pressure exerted by the incoming water.
7. However, the resistance provided by the cellulose-rich cell wall prevents the cell from bursting.
8. Instead, the cell becomes turgid, which is the state where the cell is swollen and firm, due to the influx of water.
9. In plant cells, turgor pressure is exerted against the cell wall, allowing the cell to maintain its shape and remain rigid.
10. This turgor pressure is important for supporting the plant structure, as well as aiding in processes like cell expansion and nutrient transport.
In summary, the resistance provided by the cellulose cell wall prevents plant cells from bursting when placed in water, and instead, they become turgid.
Yes, plant cells placed in water will not burst due to the resistance of cellulose. The cell wall of a plant cell is made up of cellulose, which provides strength and rigidity to the cell. This cell wall acts as a protective barrier and helps prevent the cell from bursting or breaking even when placed in a hypotonic solution, such as water.
To understand why plant cells do not burst in water, we need to consider the concept of osmosis. Osmosis is the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration, across a semi-permeable membrane.
In a hypotonic solution, like pure water, the solute concentration is lower outside the plant cell compared to the cytoplasm inside the cell. As a result, water molecules move into the cell through the semi-permeable cell membrane, trying to equalize the concentration inside and outside the cell. This influx of water can create osmotic pressure within the cell.
However, the plant cell wall made of cellulose exerts an outward pressure on the cell membrane, known as turgor pressure. The rigid cell wall, in conjunction with turgor pressure, helps maintain the shape and integrity of the cell. This prevents the cell from bursting, even when water enters the cell through osmosis.
In summary, the resistance provided by the cellulose cell wall of plant cells, along with the turgor pressure generated by the influx of water, prevents the cells from bursting when placed in water.
