TEST REVIEW: Cells & Cell Transport

Front

Which structures are found in plant cells, but not in animal cells?

Back

Chloroplasts, cell walls, central vacuole.

Front

True or False: Large molecules, such as glucose, can easily pass through the cell membrane without any help.

Back

False: They need a protein channel.

Front

All living things are made of...

Back

Cells.

Front

What is it called when large molecules move across the cell membrane from an area of high concentration to an area of low concentration through a protein channel?

Back

Facilitated Diffusion.

Front

What is the difference between active and passive transport?

Back

Active uses ATP (energy) and passive does not need energy.

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting sunlight into energy.

Front

What is the role of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, maintaining homeostasis.

Front

Define osmosis.

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane using energy (ATP) against their concentration gradient.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration.
