Front

What is the function of the endoplasmic reticulum in a cell?

Back

The endoplasmic reticulum (ER) is responsible for the synthesis of proteins and lipids, and it serves as a transport system within the cell.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a defined nucleus and organelles.

Front

What role does the Golgi body play in a cell?

Back

The Golgi body packages, modifies, and distributes proteins and lipids for secretion or use within the cell.

Front

Who was the first scientist to observe cells under a microscope?

Back

Robert Hooke was the first scientist to observe cells and coined the term 'cell'.

Front

What gives the rough endoplasmic reticulum its 'rough' appearance?

Back

The rough endoplasmic reticulum is 'rough' due to the presence of ribosomes on its surface.

Front

What is the primary function of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration.

Front

What is the function of lysosomes in a cell?

Back

Lysosomes contain digestive enzymes that break down waste materials and cellular debris.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis by translating messenger RNA (mRNA) into polypeptides.

Front

How do plant cells differ from animal cells?

Back

Plant cells have a cell wall, chloroplasts for photosynthesis, and large central vacuoles, while animal cells do not.

Front

What is the significance of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.
