What is plasmolysis pressure?
Plasmolysis pressure is the pressure exerted on the cell membrane when a plant cell loses water and shrinks away from the cell wall. This pressure is caused by the shrinking of the cytoplasm away from the cell wall, leading to a decrease in turgor pressure within the cell.
What is an example of changing turgor pressure?
An example of changing turgor pressure is when a plant wilts due to water loss. As the cell loses water, the turgor pressure decreases, causing the cell to lose its rigidity and the plant to wilt. When the plant is watered, the turgor pressure increases, restoring the cell's rigidity and the plant stands upright again.
What is The pressure exerted against the cell membrane and cell wall known as?
The pressure exerted against the cell membrane and cell wall is known as turgor pressure. It is generated by the osmotic flow of water into the cell, causing the cell to become rigid and maintain its shape.
The internal pressure of a plant cell is called what?
turgor pressure, also turgidity, is the main pressure exerted by cell contents against the cell walls in plant cells
What causes a plant cell to wilt when it is not full?
When a plant cell is not full, it wilts due to the loss of turgor pressure. Turgor pressure is the pressure exerted on the cell wall by the fluid inside the cell. Without enough water to maintain this pressure, the cell loses its rigidity and wilts.
Why soil mechanics as a separate discipline from the general mechanics?
Soil mechanics is separate from general mechanics because soil is a complex material with unique properties like porosity, compressibility, and shear strength that require specialized study. Understanding the behavior of soil is crucial for geotechnical engineering projects such as foundations, retaining walls, and earth dams, making soil mechanics an essential discipline in civil engineering.

What is horizontal pressure?
Horizontal pressure refers to the lateral force exerted by a fluid or solid material in a horizontal direction. In engineering and geotechnical contexts, it often pertains to the pressure that soil or water exerts on structures like retaining walls or underground structures. This pressure can influence the stability and design of these structures, and it is typically calculated using principles of fluid mechanics and soil mechanics. Understanding horizontal pressure is crucial for ensuring safety and structural integrity in construction projects.
What is equipotential line in soil mechanics?
lines that all the points on it have the same head pressure and eqipotential lines are always prependicular to the stream lines .
Why are soil and soil mechanics importance to the civil engineers?
Sand
What is unsaturated soil mechanics?
Unsaturated soil mechanics is the study of the behavior of soil when it contains both air and water in its pore spaces. This differs from saturated soil mechanics, which deals with soil that is completely saturated with water. Understanding unsaturated soil mechanics is crucial in various geotechnical engineering applications, such as slope stability analysis and foundation design.
Is codes for soil mechanics?
yes

What is the difference and connection between soil mechanics and foundation engineering?
soil mechanics is the science dealing with soil to knowing ,type of soil , bearing capacity of the slackening weakness and strength of the soil and by soil mechanics can we give a recommendation to the designer Foundation engineering is design of foundation of any projects ,building ,factories ,stores ....)the design of foundation type depended on the bearing capacity of the soil of the concerned site of the project.
Why study soil mechanics as a separate discipline?
Soil Mechanics like fluids mechanics and structural mechanics and engineering surveying are the core disciplines of civil engineering for well over 70 years from the days of Terzaghi, father of soil mechanics. It is a separate discipline since soil behaviour cannot be predicted like the methods used for testing the behaviour of structures and fluids,yet ideas similar to these disciplines have been used but the testing and classification of soil had to be on its own. Now the discipline has a broad base to be known as geotechnics or geotechnical engineering.
Define pressure bulb in soil mechanics?
Shape: The pressure bulb is typically depicted as a three-dimensional shape, often resembling an inverted cone or pyramid. It extends downwards from the base of the loaded area or foundation into the soil. Distribution: Within the pressure bulb, the pressure is not uniformly distributed. It is highest at the base of the loaded area and decreases with depth. The pressure distribution is influenced by factors such as the shape and size of the foundation, the load magnitude, and the properties of the soil. Depth: The depth of the pressure bulb varies depending on the characteristics of the foundation and the soil. Deeper foundations will have deeper pressure bulbs.
