Cells and Cell Transport

Front

What do eukaryotic cells contain?

Back

Eukaryotic cells contain a nucleus, specialized organelles, and genetic material.

Front

What is the type of cell transport that does not require energy?

Back

Passive Transport.

Front

What structure serves as the cell's boundary from its environment?

Back

Cell membrane.

Front

What are the two main components of the cell membrane?

Back

Proteins and lipids.

Front

How does a cell move particles against the concentration gradient?

Back

By active transport.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.

Front

Define 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 passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, typically from an area of higher concentration to an area of lower concentration.

Front

What role do channel proteins play in cell transport?

Back

Channel proteins facilitate the passive transport of specific molecules across the cell membrane.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
