Sample WAEC GCE Biology Essay Questions:
- Explain the process of photosynthesis and the importance of this process to plants.
- Answer: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells, where chlorophyll absorbs light energy. The general equation for photosynthesis is 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂. Photosynthesis is important because it provides the primary source of energy for all living organisms and releases oxygen, which is essential for respiration.
- Discuss the differences between mitosis and meiosis.
- Answer: Mitosis is a type of cell division that results in two identical daughter cells with the same number of chromosomes as the parent cell. It occurs in somatic cells for growth and repair. Meiosis, on the other hand, is a type of cell division that results in four non-identical daughter cells, each with half the number of chromosomes of the parent cell. It occurs in gametes (sex cells) for the purpose of sexual reproduction. While mitosis results in diploid cells, meiosis results in haploid cells.
- Describe the structure and function of the human heart.
- Answer: The human heart is a muscular organ located in the thoracic cavity, between the lungs. It has four chambers: two atria (upper chambers) and two ventricles (lower chambers). The right side of the heart pumps deoxygenated blood to the lungs through the pulmonary artery, while the left side pumps oxygenated blood to the rest of the body through the aorta. Valves between the chambers ensure a unidirectional flow of blood. The heart functions as a pump, maintaining blood circulation throughout the body, delivering oxygen and nutrients to tissues, and removing carbon dioxide and waste products.
These questions should provide a solid basis for your study and help you prepare for the types of questions that might appear in your WAEC GCE Biology exam.
