What is the nucleolus?

Back

The nucleolus is a dense, spherical structure found within the nucleus of eukaryotic cells, responsible for ribosome production.

Front

What is the rough endoplasmic reticulum (rough ER)?

Back

The rough ER is a type of endoplasmic reticulum studded with ribosomes, involved in protein synthesis and processing.

Front

What is the Golgi body?

Back

The Golgi body, or Golgi apparatus, is an organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the mitochondria?

Back

Mitochondria are double-membraned organelles known as the powerhouses of the cell, where ATP (energy) is produced through cellular respiration.

Front

What are centrioles?

Back

Centrioles are cylindrical structures found in animal cells that play a key role in cell division by helping to organize the mitotic spindle.

Front

What is the function of the nucleus?

Back

The nucleus is the control center of the cell, containing the cell's genetic material (DNA) and regulating gene expression.

Front

What is the cytoplasm?

Back

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

Front

What is the smooth endoplasmic reticulum (smooth ER)?

Back

The smooth ER is a type of endoplasmic reticulum that lacks ribosomes and is involved in lipid synthesis and detoxification.

Front

What is the role of ribosomes?

Back

Ribosomes are molecular machines that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the cell wall?

Back

The cell wall is a rigid outer layer found in plant cells, fungi, and bacteria that provides structural support and protection.
