Cells Structure,Transport and Protists- EOC Review

Front

What happens to a cell in a hypotonic solution?

Back

The cell will swell due to the influx of water.

Front

What does it mean that a cell membrane is semi-permeable?

Back

It allows some substances to pass through while blocking others.

Front

What is facilitated diffusion?

Back

It is the process of molecules diffusing with the concentration gradient through a protein channel.

Front

What is passive transport?

Back

Transport of substances across a cell membrane without the use of energy.

Front

What is osmosis?

Back

The diffusion of water across a semi-permeable membrane.

Front

What is active transport?

Back

The movement of substances against their concentration gradient, requiring energy.

Front

What is the function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What are protists?

Back

A diverse group of eukaryotic microorganisms, which can be unicellular or multicellular.

Front

What is the role of protein channels in cell membranes?

Back

To facilitate the transport of specific molecules across the membrane.

Front

What is the difference between simple diffusion and facilitated diffusion?

Back

Simple diffusion does not require a protein channel, while facilitated diffusion does.
