Cell Membrane and Cell Transport

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What type of transport does not require energy?

Back

Passive transport is the type of transport that does not require energy.

Front

What structure in a plant cell prevents it from bursting in pure water?

Back

The cell wall is the structure that prevents a plant cell from bursting in pure water.

Front

What is osmosis?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of transporting molecules across a membrane with the help of proteins, without using energy.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What role do transport proteins play in cell transport?

Back

Transport proteins assist in the movement of substances across the cell membrane, either by facilitating diffusion or by actively transporting molecules.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

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 moving into the cell.
