Cell Transport

Front

What does the term 'hydrophilic' mean?

Back

Hydrophilic refers to substances that are 'water-loving' and can easily interact with water.

Front

What is active transport?

Back

Active transport is the movement of molecules against a concentration gradient, requiring energy.

Front

What happens to a cell in a hypertonic solution?

Back

Water moves out of the cell, causing it to shrink.

Front

What is osmosis?

Back

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

Front

What is the difference between simple diffusion and facilitated diffusion?

Back

Simple diffusion is the passive movement of molecules from high to low concentration without assistance, while facilitated diffusion requires specific transport proteins.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane allows certain molecules to pass through while blocking others.

Front

What is the role of transport proteins in cell transport?

Back

Transport proteins help move substances across the cell membrane, especially those that cannot pass through the lipid bilayer directly.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space.

Front

What happens to plant cells in a hypotonic solution?

Back

Plant cells swell as water enters, but they do not burst due to the rigid cell wall.

Front

What is the effect of salt on plant cells?

Back

Salt causes water to move out of plant cells, leading to cell shrinkage.
