Unit 2 The Cell Review

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes outside the cell as inside the cell, resulting in no net movement of water.

Front

What type of cell is characterized by having a membrane-bound nucleus?

Back

Eukaryote.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are cells that have a membrane-bound nucleus and membrane-bound organelles.

Front

What type of cells do not have a cell wall and are only surrounded by a cell membrane?

Back

Animal Cells.

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a simple, unicellular organism that lacks a membrane-bound nucleus and organelles.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell.

Front

What is the difference between plant and animal cells?

Back

Plant cells have a cell wall and chloroplasts, while animal cells do not.

Front

What is osmosis?

Back

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

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes outside the cell than inside, causing water to enter the cell.
