Front

What is a Prokaryote?

Back

A type of cell that lacks a nucleus and membrane-bound organelles, typically smaller and simpler than eukaryotic cells.

Front

What is a Eukaryote?

Back

A type of cell that has a nucleus and membrane-bound organelles, generally larger and more complex than prokaryotic cells.

Front

What is an Isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is a Hypertonic solution?

Back

A solution with a higher concentration of solutes outside the cell than inside, causing water to move out of the cell.

Front

What is a Hypotonic solution?

Back

A solution with a lower concentration of solutes outside the cell than inside, causing water to move into the cell.

Front

Which organelle is found only in plant cells?

Back

Chloroplast.

Front

What is diffusion?

Back

The process by which molecules move from an area of high concentration to an area of low concentration.

Front

What is the function of the cell membrane?

Back

To protect the cell and regulate what enters and exits the cell.

Front

What is cytoplasm?

Back

The jelly-like substance within the cell membrane that contains organelles and is the site of many cellular processes.

Front

What is a nucleus?

Back

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