2 What is the primary function of ribosomes in a cell?
Correct Answer:
A
Explanation: Ribosomes are responsible for synthesizing proteins by translating messenger RNA into amino acid chains.
Explanation: Ribosomes are responsible for synthesizing proteins by translating messenger RNA into amino acid chains.
3 Which organelle is known as the powerhouse of the cell?
Correct Answer:
C
Explanation: Mitochondria are known as the powerhouse of the cell because they produce ATP, the energy currency of the cell, through cellular respiration.

4 What is the primary component of the cell membrane?
Correct Answer:
A
Explanation: The cell membrane is primarily composed of a phospholipid bilayer, which provides structure and regulates what enters and exits the cell.

5 Which of the following processes involves the movement of water across a semi-permeable membrane?
Correct Answer:
C
Explanation: Osmosis is the specific process of water moving through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Explanation: Osmosis is the specific process of water moving through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
6 Which type of cell division results in four genetically diverse daughter cells?
Correct Answer:
D
Explanation: Meiosis is a type of cell division that produces four genetically diverse daughter cells, each with half the number of chromosomes of the parent cell.
Explanation: Meiosis is a type of cell division that produces four genetically diverse daughter cells, each with half the number of chromosomes of the parent cell.
7 What is the function of the Golgi apparatus in a cell?
Correct Answer:
D
Explanation: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.
Explanation: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.
8 In which part of the cell does cellular respiration primarily occur?
Correct Answer:
B
Explanation: Cellular respiration primarily occurs in the mitochondria, where glucose is converted into ATP.
Explanation: Cellular respiration primarily occurs in the mitochondria, where glucose is converted into ATP.
9 Which structure contains the genetic material of a cell?
Correct Answer:
B
Explanation: The nucleus contains the cell's genetic material (DNA), which regulates cell functions and reproduction.
Explanation: The nucleus contains the cell's genetic material (DNA), which regulates cell functions and reproduction.
10 What is the term for the semi-fluid substance inside the cell membrane?
Correct Answer:
A
Explanation: Cytoplasm is the semi-fluid substance that fills the cell and contains organelles, enzymes, and other materials necessary for cellular processes.
Explanation: Cytoplasm is the semi-fluid substance that fills the cell and contains organelles, enzymes, and other materials necessary for cellular processes.
11 What type of organism is composed of only one cell?
Correct Answer:
B
Explanation: Unicellular organisms are composed of a single cell, while multicellular organisms are made up of many cells.
Explanation: Unicellular organisms are composed of a single cell, while multicellular organisms are made up of many cells.
12 Which of the following is NOT a function of the cell membrane?
Correct Answer:
D
Explanation: The cell membrane regulates transport and communication but does not conduct cellular respiration, which occurs within mitochondria.
