Cell Theory and Prokaryotic vs. Eukaryotic

Front

What is the Cell Theory?

Back

The Cell Theory states that all living organisms are made up of cells, the cell is the basic unit of life, and all cells arise from pre-existing cells.

Front

What are Prokaryotic cells?

Back

Prokaryotic cells are simple, single-celled organisms that lack membrane-bound organelles and a nucleus. Examples include bacteria and archaea.

Front

What are Eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain membrane-bound organelles, including a nucleus. Examples include plant and animal cells.

Front

What is a membrane-bound organelle?

Back

A membrane-bound organelle is a specialized structure within a cell that is enclosed by a membrane, such as the nucleus, mitochondria, and endoplasmic reticulum.

Front

What is the main difference between Prokaryotic and Eukaryotic cells?

Back

The main difference is that prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

Who proposed the Cell Theory?

Back

The Cell Theory was developed by scientists Matthias Schleiden, Theodor Schwann, and Rudolf Virchow.

Front

What is the function of the nucleus in a eukaryotic cell?

Back

The nucleus stores the cell's genetic material (DNA) and controls the cell's growth, metabolism, and reproduction.

Front

What is an example of a prokaryotic organism?

Back

An example of a prokaryotic organism is Escherichia coli (E. coli), a type of bacteria.

Front

What is an example of a eukaryotic organism?

Back

An example of a eukaryotic organism is a human, which is made up of eukaryotic cells.

Front

What does it mean that all cells come from pre-existing cells?

Back

It means that new cells are produced by the division of existing cells, not spontaneously.
