Cell Organelles and Their Functions

Front

What is the function of the Nucleus in a cell?

Back

The Nucleus serves as the control center of the cell, containing genetic material (DNA) and regulating gene expression.

Front

What organelle is responsible for the synthesis of ribosomal RNA (rRNA)?

Back

Nucleolus.

Front

Which organelle is known as the powerhouse of the cell?

Back

Mitochondria, as they produce energy in the form of ATP.

Front

What is the primary function of Chloroplasts?

Back

Chloroplasts are responsible for photosynthesis, converting sunlight into chemical energy.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells are characterized by their small size, simple structure, and lack of a nucleus and membrane-bound organelles.

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

What is the function of the Golgi apparatus?

Back

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

Front

What is the function of the cell membrane?

Back

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

Front

What is the role of Lysosomes in a cell?

Back

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

Front

What is the function of the Endoplasmic Reticulum (ER)?

Back

The ER is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), and it also plays a role in detoxification.
