Front

What are the two main types of cells?

Back

The two main types of cells are prokaryotic cells (without a nucleus, e.g., bacteria) and eukaryotic cells (with a nucleus, e.g., plant and animal cells).

What is the function of the nucleus in a cell?

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, as they produce energy (ATP) through cellular respiration.

What is osmosis?

Back

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

Front

What does isotonic mean?

Back

Isotonic refers to a solution that has the same concentration of solutes as another solution, resulting in no net movement of water.
