Sarah has been studying the effect of sunlight on plant growth. She observes that a plant grows 2 cm per day with 6 hours of sunlight. If the sunlight increases to 9 hours per day, the growth rate increases by 50%. How much will the plant grow in 10 days with 9 hours of sunlight? - Groen Casting

Title: How Increased Sunlight Boosts Plant Growth: A Practical Study
When studying how environmental factors influence plant development, Sarah, an aspiring botanist, conducted a detailed observation on how sunlight duration affects a plant’s daily growth. Her findings reveal a clear correlation: sunlight directly impacts growth speed, making it a key variable in optimizing plant health.
Originally, under 6 hours of sunlight, the plant grew at a steady rate of 2 cm per day. However, when Sarah exposed the plant to extended sunlight—increasing the daily exposure from 6 to 9 hours—the growth rate improved by 50%. This significant boost demonstrates how even a few additional hours of sunlight can accelerate plant development.
Understanding the Context
Let’s break down the calculation to determine total growth over 10 days with 9 hours of daily sunlight.
At 6 hours of sunlight, growth = 2 cm/day
With a 50% increase at 9 hours:
2 cm × 1.50 = 3 cm per day
Over 10 days:
3 cm/day × 10 days = 30 cm total growth
Therefore, with 9 hours of sunlight daily, Sarah’s plant will grow 30 centimeters in 10 days—a striking example of how sunlight duration directly enhances plant development. This insight not only supports theoretical knowledge but also explains practical gardening techniques to encourage faster, healthier growth.
Key Insights
For anyone passionate about horticulture or plant science, Sarah’s experiment underscores the importance of optimizing sunlight exposure to maximize plant performance.
