Exam questions on Sexual and asexual reproduction
- A gardener in Kerala grows strawberry plants. Each plant sends out long stems called runners along the ground, and a new plant grows from each runner. Strawberry plants also produce flowers, and when these are pollinated they form fruits that contain seeds.Explain why the gardener might prefer to grow strawberry plants from runners rather than from seeds.2 marks
- A biology teacher in Cairo explains how a baby begins to develop. A sperm cell from the father joins with an egg cell from the mother.Explain why the baby will not be genetically identical to either parent.2 marks
- A microbiologist in Mexico City observes bacteria in a flask of warm nutrient broth. In ideal conditions, each bacterium divides into two about every 20 minutes.Describe how bacteria reproduce by binary fission.3 marks
