What is the function of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell, providing energy through the process of cellular respiration.

Front

How do heart muscle cells differ from skin cells in terms of mitochondria?

Back

Heart muscle cells have many more mitochondria than skin cells because they require more energy to support constant beating.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the site of protein synthesis, where amino acids are assembled into proteins.

Front

What is the structure of the cell membrane?

Back

The cell membrane is a lipid bilayer that provides a barrier and regulates what enters and exits the cell.

Front

Why do cells not dissolve when exposed to water?

Back

The lipid structure of the cell membrane allows water to bead up and roll off, preventing cells from dissolving.

Front

What is a common characteristic of both prokaryotic and eukaryotic cells?

Back

Both types of cells store their genetic code in the form of DNA.

Front

What is the plasma membrane's role in regulating cell contents?

Back

The plasma membrane regulates what goes in and out of the cell by using proteins to allow specific large molecules to cross.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform distinct processes, such as mitochondria and ribosomes.

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 the significance of the lipid bilayer in the cell membrane?

Back

The lipid bilayer provides a flexible barrier that separates the cell from its environment and helps maintain homeostasis.
