Cellular Transport

Front

What is Osmosis?

Back

The movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What type of transport requires energy?

Back

Active transport requires energy to move substances against their concentration gradient.

Front

What is a HYPOTONIC solution?

Back

A hypotonic solution has a lower concentration of solute compared to the inside of the cell.

Front

What is Active Transport?

Back

A type of transport that requires energy to move substances across a cell membrane against their concentration gradient.

Front

What does it mean for a cell membrane to be Semi or Selectively Permeable?

Back

It means that the cell membrane allows certain substances to pass through while blocking others.

Front

What is Diffusion?

Back

The movement of particles from an area of higher concentration to an area of lower concentration without the use of energy.

Front

What is Facilitated Diffusion?

Back

A process that allows substances to cross membranes with the assistance of special proteins, without using energy.

Front

What is a HYPERTONIC solution?

Back

A hypertonic solution has a higher concentration of solute compared to the inside of the cell.

Front

What is Isotonic solution?

Back

An isotonic solution has an equal concentration of solute compared to the inside of the cell, resulting in no net movement of water.

Front

What is the role of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.
