Sample Questions and Answers
To give you a better idea of what to expect, here are some sample questions and answers from the Wassce 2019 Biology Questions.
Multiple-Choice Questions
1. Which of the following is the primary site of photosynthesis in a plant cell?
| A | B | C | D |
|---|---|---|---|
| Mitochondria | Chloroplasts | Ribosomes | Nucleus |
Answer: B. Chloroplasts
2. What is the process by which genetic material is transferred from one organism to another?
| A | B | C | D |
|---|---|---|---|
| Mitosis | Meiosis | Genetic engineering | Natural selection |
Answer: C. Genetic engineering
Essay Questions
1. Explain the process of osmosis and its significance in biological systems.
Osmosis is the movement of water molecules from an area of high water concentration to an area of low water concentration through a semi-permeable membrane. This process is crucial for maintaining the balance of water and solutes in cells and tissues. For example, in plant cells, osmosis helps to maintain turgor pressure, which is essential for the plant's structure and growth. In animal cells, osmosis plays a role in the regulation of cell volume and the transport of nutrients and waste products.
📝 Note: Ensure you understand the underlying principles of osmosis and provide relevant examples to support your answer.
2. Discuss the role of enzymes in biological processes.
Enzymes are biological catalysts that speed up chemical reactions in living organisms. They play a crucial role in various biological processes, including digestion, respiration, and DNA replication. Enzymes work by lowering the activation energy required for a reaction to occur, making the reaction more efficient. Each enzyme is specific to a particular substrate, meaning it can only catalyze a specific reaction. Enzymes are also affected by factors such as temperature, pH, and the presence of inhibitors, which can alter their activity.
📝 Note: Provide detailed examples of enzymes and their functions to illustrate your understanding.
Preparation Tips for Wassce 2019 Biology Questions
