Parts of Cell

Front

What is the function of ribosomes in a cell?

Back

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

Front

What is the role of the cell membrane?

Back

The cell membrane protects the cell, provides structure, and regulates the movement of substances in and out of the cell.

Front

What organelle is responsible for photosynthesis in plant cells?

Back

Chloroplasts are the organelles that use energy from sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the primary function of mitochondria?

Back

Mitochondria break down food molecules to release energy in the form of adenosine triphosphate (ATP), often referred to as the powerhouse of the cell.

Front

What is a large central vacuole and its function in plant cells?

Back

A large central vacuole stores water, nutrients, and waste products, and helps maintain turgor pressure in plant cells.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various membrane-bound organelles.

Front

What is the function of the nucleus in a cell?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities by regulating gene expression.

Front

What are lysosomes and their function?

Back

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

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), and it also plays a role in detoxification.

Front

What is the function of the Golgi apparatus?

Back

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