Cell Structure and Function

Front

What is the function of the Golgi body in a cell?

Back

The Golgi body modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What role do centrioles play in cell division?

Back

Centrioles help organize the mitotic spindle and are essential for proper chromosome separation during cell division.

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 structural support.

Front

What distinguishes eukaryotic cells from prokaryotic cells?

Back

Eukaryotic cells contain a true nucleus and membrane-bound organelles, while prokaryotic cells do not.

Front

What is the role of ribosomes in a cell?

Back

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

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

How do lysosomes contribute to cellular function?

Back

Lysosomes contain digestive enzymes that break down waste materials and cellular debris.

Front

What is the significance of the endoplasmic reticulum (ER) in a cell?

Back

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

Front

What is the function of mitochondria in eukaryotic cells?

Back

Mitochondria are known as the powerhouses of the cell, generating ATP through cellular respiration.

Front

What is the role of the nucleus in a cell?

Back

The nucleus houses the cell's genetic material (DNA) and is responsible for regulating gene expression and cell division.
