T7D6 Cellular Transport

Front

What characteristic determines what goes in and out of a cell?

Back

Semi-permeability is the property of cell membranes that allows certain molecules to pass through while blocking others.

Front

Which type of transport is facilitated diffusion in?

Back

Facilitated diffusion is a type of passive transport that does not require energy.

Front

Which type of transport requires a protein aid?

Back

Facilitated diffusion requires a protein aid to help transport molecules across the cell membrane.

Front

What is it called when a cell has a higher salt level on the inside than on the outside?

Back

Hypotonic refers to a solution where the concentration of solutes is lower outside the cell than inside.

Front

Which type of passive transport functions with water?

Back

Osmosis is the passive transport of water across a semi-permeable membrane.

Front

What is the function of the cell membrane?

Back

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

Front

Define osmosis.

Back

Osmosis is the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

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 does isotonic mean?

Back

Isotonic refers to a solution where the concentration of solutes is equal inside and outside the cell.
