Key Stage 3 (KS3) Plants Practice Test

Wilting leaves are a clear indication of poor health in a plant. When a plant is healthy, its leaves are typically firm, turgid, and vibrant. Wilting occurs when a plant loses water faster than it can take it up from the soil, which can be due to various factors such as insufficient watering, root damage, or disease. This physiological response signals stress and can lead to a decline in overall plant health if not addressed promptly.

In contrast, strong stems indicate a robust structure and a healthy support system for the plant, while regular growth patterns and bright green foliage are signs of good health and proper functioning. Healthy plants usually exhibit consistent growth and vibrant foliage, which are indicative of effective photosynthesis and nutrient uptake.
