Cells and Cell Transport

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy. It occurs along the concentration gradient, from areas of higher concentration to areas of lower concentration.

Front

What is an isotonic solution?

Back

An isotonic solution is a solution in which the concentration of solutes is the same inside and outside of the cell, resulting in no net movement of water.

Front

What do prokaryotic and eukaryotic cells have in common?

Back

Both prokaryotic and eukaryotic cells contain DNA as their genetic material.

Front

What is osmosis?

Back

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

Front

What is the function of the cell membrane?

Back

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

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy (usually in the form of ATP).

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform specific functions, such as the nucleus, mitochondria, and ribosomes.

Front

What is the role of the nucleus in a cell?

Back

The nucleus is the organelle that contains the cell's genetic material (DNA) and controls cellular activities.
