Cell Structure and Function

Front

What is a eukaryotic cell?

Back

A eukaryotic cell is a type of cell that contains a nucleus and membrane-bound organelles. Examples include plant and animal cells.

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a type of cell that lacks a membrane-bound nucleus and organelles. Bacteria are examples of prokaryotic cells.

Front

What is the function of the cell membrane?

Back

The cell membrane surrounds the cell, providing structure and regulating the movement of substances in and out of the cell.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform specific functions, such as mitochondria for energy production and ribosomes for protein synthesis.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the role of the nucleus in a eukaryotic cell?

Back

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

Front

What is a cell wall?

Back

A cell wall is a rigid outer layer that provides support and protection to certain types of cells, such as plant cells and bacteria.

Front

What is cytoplasm?

Back

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

Front

What are ribosomes?

Back

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

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, as they produce energy (ATP) through cellular respiration.
