Cell Biology Review

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA (mRNA).

Front

What role do lysosomes play in cellular function?

Back

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

Front

What is cytoplasm and what is its significance in a cell?

Back

Cytoplasm is the jelly-like substance within the cell membrane that contains organelles and is the site for many metabolic processes.

Front

What is the function of Golgi bodies in a cell?

Back

Golgi bodies package, modify, and transport proteins and lipids to different destinations within or outside the cell.

Front

What distinguishes rough Endoplasmic Reticulum from smooth Endoplasmic Reticulum?

Back

Rough Endoplasmic Reticulum has ribosomes on its surface, which are involved in protein synthesis, while smooth Endoplasmic Reticulum lacks ribosomes and is involved in lipid synthesis and detoxification.

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 are mitochondria known as and what is their function?

Back

Mitochondria are known as the powerhouse of the cell, as they generate 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.

Front

What is the function of the cytoskeleton?

Back

The cytoskeleton provides structural support, maintains cell shape, and facilitates cell movement and division.

Front

What is the purpose of the cell wall in plant cells?

Back

The cell wall provides rigidity, protection, and structural support to plant cells.
