1. Cell Structure and Function
Question 1: What are the basic components of a cell?
Answer 1: Cells consist of the cell membrane, nucleus, mitochondria, endoplasmic reticulum,
Golgi apparatus, and lysosomes.
Question 2: How does the cell membrane regulate what enters and exits the cell?
Answer 2: The cell membrane is selectively permeable, allowing certain molecules to pass
through while restricting others based on size, charge, and solubility.
Question 3: What is the function of mitochondria in a cell?
Answer 3: Mitochondria produce ATP (adenosine triphosphate), the cell's primary energy
currency, through cellular respiration.
Question 4: Where is genetic material stored in a cell?
, Answer 4: Genetic material is stored in the nucleus, where DNA is organized into chromosomes.
Question 5: What role do lysosomes play in the cell?
Answer 5: Lysosomes contain digestive enzymes that break down waste materials and recycle
cellular components.
2. Cellular Processes
Question 6: Describe the process of cellular respiration.
Answer 6: Cellular respiration is a series of metabolic processes that convert glucose and
oxygen into ATP, carbon dioxide, and water.
Question 7: What is the difference between mitosis and meiosis?
Answer 7: Mitosis produces two identical daughter cells with the same number of chromosomes,
while meiosis produces four genetically diverse gametes (sex cells).
Question 8: How do cells communicate with each other?
Answer 8: Cells communicate through chemical signals such as hormones, neurotransmitters,
and cytokines, as well as through direct contact and electrical signals.
Question 9: What is the purpose of protein synthesis in cells?
Answer 9: Protein synthesis produces proteins that are essential for cellular structure, function,
and regulation of biochemical reactions.
Question 10: How does the endoplasmic reticulum contribute to protein synthesis?
Answer 10: The endoplasmic reticulum (ER) synthesizes and modifies proteins before they are
transported to their final destination in the cell.
3. Genetics and Molecular Biology
Question 11: What is the structure of DNA?
Answer 11: DNA is a double-stranded helix composed of nucleotide bases adenine (A), thymine
(T), cytosine (C), and guanine (G), held together by hydrogen bonds.
