Cell Types and Organelles

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a type of cell that is always unicellular, lacks a nucleus, and has free-floating genetic material (DNA).

Front

What is a eukaryotic cell?

Back

A eukaryotic cell is a type of cell that has a nucleus and can be unicellular or multicellular.

Front

What is the function of the cell wall?

Back

The cell wall provides rigidity and structural support to the cell, helping to maintain its shape.

Front

What is the role of chloroplasts in a cell?

Back

Chloroplasts are organelles involved in photosynthesis, converting light energy into chemical energy in the form of glucose.

Front

What are the main differences between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells are unicellular, lack a nucleus, and have free-floating DNA, while eukaryotic cells can be unicellular or multicellular, have a nucleus, and contain membrane-bound organelles.

Front

What is the significance of the nucleus in eukaryotic cells?

Back

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

Front

What are organelles?

Back

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

Front

What is the function of ribosomes?

Back

Ribosomes are organelles responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the role of the plasma membrane?

Back

The plasma membrane is a selective barrier that regulates the entry and exit of substances in and out of the cell.

Front

What is cytoplasm?

Back

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