Cell Organelles & Functions

Front

What is the function of the nucleolus in a cell?

Back

The nucleolus is found inside the nucleus and produces ribosomes.

Front

What is the role of the nucleus in a cell?

Back

The nucleus is the control center of the cell and contains DNA.

Front

Describe the structure and function of centrioles.

Back

Centrioles are cylinder-shaped organelles made of short microtubules arranged in a circle, and they play a role in cell division.

Front

What is the primary function of ribosomes?

Back

Ribosomes assemble amino acids to create proteins.

Front

What is the cytoskeleton and its role in the cell?

Back

The cytoskeleton is a network of proteins that is constantly changing to meet the needs of a cell; it is made of small protein subunits that form long threads or fibers that crisscross the entire cell.

Front

What are organelles and why are they important?

Back

Organelles are specialized structures within a cell that perform distinct processes; they are important for maintaining cellular functions.

Front

How do ribosomes differ from other organelles in terms of structure?

Back

Ribosomes are not membrane-bound organelles; they are made of RNA and proteins and can be found free in the cytoplasm or attached to the endoplasmic reticulum.

Front

What is the significance of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, providing protection and structural support.

Front

Explain the function of mitochondria in a cell.

Back

Mitochondria are known as the powerhouse of the cell; they produce energy in the form of ATP through cellular respiration.

Front

What is the role of the endoplasmic reticulum (ER)?

Back

The endoplasmic reticulum is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), as well as the transport of materials within the cell.
