Flashcard: Cell Membrane & Cell Transport

Front

What is Homeostasis?

Back

A balance that an organism maintains by regulating what goes into and out of the cell.

Front

What happens to a plant cell in a hypotonic solution?

Back

The plant cell swells due to water entering the cell.

Front

What is a Hypertonic solution?

Back

A solution that has a higher concentration of solutes compared to another solution, causing water to leave the cell.

Front

What happens to a plant cell with a 20% salt solution placed in a 10% salt solution?

Back

The plant cell will swell as water moves into the cell.

Front

What is Passive Transport?

Back

The type of cellular transport that requires no energy, allowing substances to move across the cell membrane by diffusion.

Front

What is Plasmolysis?

Back

The process in which cells lose water in a hypertonic solution, causing the cell membrane to pull away from the cell wall.

Front

What is Cytolysis?

Back

The bursting of a cell due to excessive water intake in a hypotonic solution.

Front

What is an Isotonic solution?

Back

A solution that has the same concentration of solutes as another solution, resulting in no net movement of water.

Front

What is Active Transport?

Back

The movement of substances across a cell membrane against their concentration gradient, requiring energy.

Front

What role do protein pumps play in cell transport?

Back

They help move ions and molecules across the cell membrane during active transport.
