What are ribosomes?

Back

Ribosomes are small structures within cells that synthesize proteins by translating messenger RNA (mRNA). They can be found floating freely in the cytoplasm or attached to the rough endoplasmic reticulum.

Front

What is a centriole?

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 chromatin?

Back

Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells. It condenses to form chromosomes during cell division.

Front

What is the Golgi apparatus?

Back

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

Front

What is the rough endoplasmic reticulum?

Back

The rough endoplasmic reticulum (RER) is a type of endoplasmic reticulum that is studded with ribosomes, making it the site of protein synthesis and processing.

Front

What is the function of the mitochondrion?

Back

Mitochondria are known as the powerhouses of the cell, as they generate adenosine triphosphate (ATP) through cellular respiration.

Front

What is the cytoplasm?

Back

Cytoplasm is the jelly-like substance that fills the interior of a cell, providing a medium for chemical reactions and supporting organelles.

Front

What is the role of vesicles in a cell?

Back

Vesicles are small membrane-bound sacs that transport materials within the cell and to the cell membrane for secretion.

Front

What is the function of the cell membrane?

Back

The cell membrane is a protective barrier that regulates what enters and exits the cell, maintaining homeostasis.

Front

What is the nucleus?

Back

The nucleus is the membrane-bound organelle that contains the cell's genetic material (DNA) and controls cellular activities.
