I'm sorry, but I cannot answer all the questions in the question paper as I do not have access to the specific questions you are referring to. However, if you provide me with the questions, I will do my best to answer them to the best of my ability.

Section A: Multiple Choice Questions (1 point each)
1. Which of the following is NOT a function of the cell membrane?
(a) Regulating transport of substances
(b) Protecting the cell
(c) Synthesizing proteins
(d) Maintaining cell shape
2. The process by which cells use energy to pump substances against their concentration gradient is called:
(a) Diffusion
(b) Facilitated diffusion
(c) Active transport
(d) Osmosis
3. Which of the following is the smallest unit of life?
(a) Atom
(b) Molecule
(c) Cell
(d) Organism
4. The site of protein synthesis in the cell is the:
(a) Ribosome
(b) Nucleolus
(c) Golgi apparatus
(d) Mitochondrion
5. Which type of cell division produces gametes (eggs and sperm)?
(a) Mitosis
(b) Meiosis
(c) Binary fission
(d) Budding
Section B: Short Answer Questions (2 points each)
1. Describe the structure of the eukaryotic cell membrane.
2. Explain the difference between passive and active transport.
3. What is the role of the nucleus in the cell?
4. Describe the process of photosynthesis.
5. How does the immune system protect the body?
Section C: Essay Question (5 points)
1. Discuss the importance of cell division in living organisms, explaining the differences between mitosis and meiosis.
Answer Key
Section A
1. (c)
2. (c)
3. (c)
4. (a)
5. (b)
Section B
1. The eukaryotic cell membrane is a phospholipid bilayer with embedded proteins. It has a hydrophilic (water-loving) head and a hydrophobic (water-repelling) tail.
2. Passive transport is the movement of substances down their concentration gradient, while active transport is the movement of substances against their concentration gradient with the use of energy.
3. The nucleus contains the cell's DNA and is responsible for controlling cell activities and reproduction.
4. Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose (sugar) and oxygen.
5. The immune system protects the body from infection by recognizing and destroying foreign substances, such as bacteria, viruses, and fungi.
Section C
1. Cell division is essential for growth, repair, and reproduction in living organisms. Mitosis is the process by which a cell divides into two identical daughter cells, while meiosis is the process by which a cell divides into four genetically unique daughter cells. Mitosis is used for growth and repair, while meiosis is used for gamete production.
