Cell Parts Functions Quiz
- 1.
What is the function of the nucleus?
- A.
Break down & recycle molecules
- B.
Store materials
- C.
Contain DNA (information) & direct activities of the cell
- D.
Regulate materials entering and leaving the cell
Correct Answer
C. Contain DNA (information) & direct activities of the cellExplanation
The nucleus functions to contain the DNA, which holds the genetic information of the cell. It also directs the activities of the cell by controlling the synthesis of proteins through the process of transcription and translation. The nucleus plays a crucial role in regulating the cell's functions and ensuring that it carries out its tasks efficiently.Rate this question:

What is the function of the Cell Membrane?
- A.
Break down & recycle molecules
- B.
Modify, sort, and package proteins & lipids
- C.
Convert chemical energy in food to usable energy
- D.
Regulate materials entering and leaving the cell
Correct Answer
D. Regulate materials entering and leaving the cellExplanation
The cell membrane acts as a barrier, controlling the movement of substances in and out of the cell. It regulates the entry of essential nutrients and ions into the cell, while also preventing the passage of harmful substances. Additionally, it helps to maintain the cell's internal environment by controlling the exit of waste products and other molecules. Therefore, the function of the cell membrane is to regulate materials entering and leaving the cell.Rate this question:

What is the function of the mitochondria?
- A.
Convert chemical energy in food to usable energy
- B.
Store materials
- C.
Regulate materials entering and leaving the cell
- D.
Assemble proteins/lipids
Correct Answer
A. Convert chemical energy in food to usable energyExplanation
The mitochondria are often referred to as the "powerhouses" of the cell because their main function is to convert the chemical energy found in food molecules into a usable form of energy called adenosine triphosphate (ATP). This process, known as cellular respiration, occurs within the mitochondria's inner membrane and produces ATP through a series of complex reactions. The ATP molecules are then used by the cell to carry out various functions and activities, providing the energy needed for cellular processes such as growth, movement, and reproduction.Rate this question:

What is the function of the Golgi Apparatus?
- A.
Store materials
- B.
Modify, sort, and package proteins & lipids
- C.
Synthesize proteins
- D.
Break down and recycle molecules
Correct Answer
B. Modify, sort, and package proteins & lipidsExplanation
The Golgi Apparatus is responsible for modifying, sorting, and packaging proteins and lipids. It receives these molecules from the endoplasmic reticulum and then modifies them by adding sugars, lipids, or phosphate groups. It also sorts the molecules and directs them to their appropriate destinations within the cell. Finally, the Golgi Apparatus packages the molecules into vesicles, which can then be transported to other parts of the cell or released outside of the cell.Rate this question:

What is the function of the vacuole?
- A.
Store materials
- B.
Break down & recycle molecules
- C.
Regulate materials entering and leaving the cell
- D.
Modify, sort, and package proteins & lipids
Correct Answer
A. Store materialsExplanation
The vacuole is responsible for storing materials within the cell. It acts as a storage compartment, holding various substances such as water, nutrients, and waste products. This function helps maintain the overall balance and homeostasis within the cell by storing essential molecules and eliminating harmful waste.Rate this question:

What is the function of the Lysosome?
- A.
Modify, sort, and package proteins & lipids
- B.
Synthesize proteins
- C.
Break down & recycle molecules
- D.
Store materials
Correct Answer
C. Break down & recycle moleculesExplanation
The function of the Lysosome is to break down and recycle molecules. Lysosomes contain enzymes that can break down various types of molecules, such as proteins, lipids, carbohydrates, and nucleic acids. This process, known as hydrolysis, allows the lysosome to break down complex molecules into their smaller components, which can then be recycled by the cell for energy or used to build new molecules. Additionally, lysosomes are involved in the degradation of cellular waste and the removal of damaged organelles, contributing to the overall recycling and maintenance of cellular components.Rate this question:
