Key Stage 3 (KS3) Plants Practice Test

Water supply is indeed one of the main factors affecting plant growth. Plants rely on water for numerous vital processes, including photosynthesis, nutrient transport, and maintaining turgor pressure, which helps them stay upright and healthy. Adequate water is necessary for roots to absorb nutrients from the soil. Without sufficient water, plants can experience stress, leading to wilting, reduced growth, and even death.

While wind speed, soil temperature, and humidity levels can influence plant growth in different ways, water supply is crucial because all living organisms need water to survive. Understanding the importance of water helps in recognizing its role in ensuring that plants thrive in their environment.
