Diffusion Test

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What role does the cell membrane play in diffusion?

Back

The cell membrane controls the passage of materials into and out of the cell, allowing for selective permeability.

Front

What happens to plant cells when placed in a hypertonic solution?

Back

Plant cells will lose water, causing them to shrink and potentially die.

Front

What is the significance of using iodine in starch testing?

Back

Iodine is used to test for the presence of starch; it turns blue-black in the presence of starch.

Front

How does salt affect plant cells?

Back

Salt can cause plant cells to lose water, leading to cell shrinkage and potential death.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, leading to water entering the cell.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, leading to water leaving the cell.

Front

What is the effect of a 15% salt solution on plant cells?

Back

A 15% salt solution will cause plant cells to lose water and shrink.

Front

What is selective permeability?

Back

Selective permeability is the ability of a cell membrane to allow certain substances to pass while blocking others.
