Cell organelles:Structure and Function

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a type of cell that does not have a membrane-bound nucleus or organelles. Examples include bacteria.

Front

What is a eukaryotic cell?

Back

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

Front

What is the function of the nucleus in a cell?

Back

The nucleus stores the cell's genetic material (DNA) and controls the cell's activities.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell; they generate energy in the form of ATP through cellular respiration.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is a vacuole?

Back

A vacuole is a membrane-bound organelle that stores substances such as food, water, and waste. It is typically larger in plant cells.

Front

What is the cell membrane?

Back

The cell membrane is a protective barrier that surrounds the cell, controlling the movement of substances in and out.

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 cellular processes.

Front

What are ribosomes?

Back

Ribosomes are small structures that synthesize proteins by translating messenger RNA.

Front

What is the endoplasmic reticulum (ER)?

Back

The endoplasmic reticulum is an organelle that helps in the synthesis of proteins (rough ER) and lipids (smooth ER).
