Cell Organelles and Their Functions

Click on the flashcard to see the answer



What is the function of the nucleus in a cell?

The nucleus acts as the control center of the cell, containing DNA and responsible for regulating activities like growth and reproduction.

Which organelle is responsible for energy production in cells?

The mitochondria are responsible for energy production, generating ATP through cellular respiration.

What is the role of ribosomes in the cell?

Ribosomes are responsible for protein synthesis, translating genetic information to make proteins.

What function does the cell membrane perform?

The cell membrane regulates what enters and exits the cell, providing protection and structural support.

What is the endoplasmic reticulum (ER) and its types?

The ER is a network of membranes involved in protein and lipid synthesis, consisting of two types: rough ER (with ribosomes) and smooth ER (without ribosomes).

How does the Golgi apparatus assist the cell?

The Golgi apparatus modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.

What are lysosomes and their role in a cell?

Lysosomes are organelles containing digestive enzymes that break down waste materials and cellular debris.

What is the function of chloroplasts, and where are they found?

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy in plant cells.

What role do vacuoles play in a cell?

Vacuoles store nutrients and waste products, helping maintain pressure and balance within the cell.

What is the cytoplasm and its importance?

The cytoplasm is a jelly-like substance where organelles are suspended, aiding in cellular processes and transport.

Describe the function of the cell wall.

The cell wall provides structural support and protection, found in plant cells and some bacteria.

How do peroxisomes function within a cell?

Peroxisomes break down fatty acids and detoxify harmful substances in the cell.

What is the function of the cytoskeleton in a cell?

The cytoskeleton provides shape, support, and facilitates movement of the cell and its components.

What are centrioles and their function in the cell?

Centrioles help in cell division by assisting in the organization of the mitotic spindle.

What is the function of the nuclear envelope?

The nuclear envelope encloses the nucleus, protecting its contents and regulating material exchange with the cytoplasm.
