B1.8 Flashcards
What is osmosis in plants?
Osmosis is the movement of water into and out of plant cells.
How does osmosis help support plant stems and leaves?
It creates turgor pressure, making the cells rigid and supporting the plant.
What happens to plant cells in a HYPOTONIC solution?
They swell and become turgid.
What happens to plant cells in a HYPERTONIC solution?
They shrink and become flaccid.
What is plasmolysis?
Plasmolysis is when the cell membrane pulls away from the cell wall.
Why is turgor pressure important for plants?
Turgor pressure gives plants their shape and structure.
How can you investigate the effect of osmosis on plant tissues?
By placing plant tissues in different concentrations of solutions and measuring the changes in mass or size.
What factors can affect the rate of osmosis in plant cells?
Factors like temperature, concentration gradient, and surface area can affect the rate of osmosis.
Why is it important to control the concentration of the solution surrounding plant cells?
To maintain the right water balance in the cells and prevent plasmolysis.
How can you measure the effect of osmosis on plant tissues?
By measuring changes in mass, length, or turgor pressure.
