Front

What is DNA and what is its role in cells?

Back

DNA is the material that provides instructions for all cell processes.

Front

Where is DNA located in prokaryotic cells?

Back

In prokaryotic cells, DNA is located in the cytoplasm.

Front

Why are cells considered small?

Back

Cells are considered small because their size is limited by their outer surface area.

Front

What is the principle that states all living cells come from other living cells?

Back

This principle is known as cell theory.

Front

Do prokaryotic cells have a nucleus?

Back

No, prokaryotic cells do not have a nucleus or membrane-bound organelles.

Front

Which type of cells is normally larger: bacterial, human, or plant cells?

Back

Plant cells are normally larger than bacterial and human cells.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within a cell that are enclosed by membranes, such as the nucleus, mitochondria, and endoplasmic reticulum.

Front

What is the function of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, providing protection and support.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within a cell that contains organelles and is where many cellular processes occur.
