Cell Organelles

Front

What is the function of the mitochondrion in a cell?

Back

The mitochondrion is responsible for producing ATP (adenosine triphosphate), which is the energy currency of the cell, through the process of cellular respiration.

Front

Which organelles are typically absent in animal cells?

Back

Animal cells do not have a cell wall, central vacuole, or chloroplasts.

Front

What is the role of the cytoskeleton in a cell?

Back

The cytoskeleton helps the cell maintain its shape, provides structural support, organizes its internal components, and facilitates cell movement.

Front

How do mitochondria contribute to muscle cell function?

Back

Mitochondria generate ATP, which is essential for muscle contraction and energy during physical activity. Muscle cells contain hundreds to thousands of mitochondria to meet their high energy demands.

Front

What is the primary function of the cell membrane?

Back

The cell membrane regulates the movement of substances in and out of the cell, providing protection and maintaining homeostasis.

Front

What are the main components of the cell membrane?

Back

The cell membrane is primarily composed of a phospholipid bilayer, proteins, cholesterol, and carbohydrates.

Front

What is the difference between prokaryotic and eukaryotic cells regarding organelles?

Back

Eukaryotic cells contain membrane-bound organelles (like mitochondria and the nucleus), while prokaryotic cells do not have these structures.

Front

What is the function of chloroplasts, and in which type of cells are they found?

Back

Chloroplasts are responsible for photosynthesis and are found in plant cells and some protists.

Front

What is the significance of the central vacuole in plant cells?

Back

The central vacuole stores nutrients and waste products, helps maintain turgor pressure, and plays a role in cell growth.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.
