KS3 Plants Practice Test 2026 – Complete Exam Preparation

Seeds benefit from being dispersed primarily by reducing competition for resources. When seeds are spread away from the parent plant, they have a better chance of finding suitable conditions for growth, such as sunlight, water, and nutrients. This spatial separation prevents them from competing directly with the parent plant and each other, which can lead to higher survival rates and healthier offspring.

When seeds remain close to their parent, they often end up vying for the same resources, which can limit their growth potential and increase the likelihood of failure. Dispersal mechanisms, such as wind, water, or animals, facilitate this process by taking seeds away from areas that may already be overcrowded or where resources are depleted. This strategy increases the chances that at least some seeds will find favorable environments to germinate and thrive.
