Question No. 1
How much oxygen can one acre of grass produce per day?

One acre of grass can produce enough oxygen for approximately ___ people daily. This is because grass, like all green plants, undergoes photosynthesis, a process that converts carbon dioxide and sunlight into oxygen and glucose. The significant oxygen production by grass highlights its ecological importance. Grass-covered areas not only contribute to air purification but also aid in carbon sequestration, capturing and storing carbon dioxide from the atmosphere, which is crucial for mitigating climate change. According to studies, well-maintained lawns and grasslands can greatly impact improving urban air quality.

Question No. 3
What percentage of a grass leaf is made up of water?

Grass leaves are composed of _____________ water, making water a critical component of their structure. This high water content helps maintain the plant's turgidity, which is necessary for its upright growth and overall health. Water is vital for photosynthesis, the process by which grass and other plants produce food. Additionally, water aids in nutrient transport within the plant and helps regulate its temperature. Maintaining adequate water levels in grass is essential for its survival, especially during hot and dry conditions.

Question No. 4
How much cooler can a natural green lawn be compared to synthetic grass on a hot day?

On a hot day, a natural green lawn can be up to ___ degrees Fahrenheit cooler than synthetic grass. This significant temperature difference is due to the natural cooling effect of the transpiration process in real grass. Transpiration involves water evaporation from the grass blades, which cools the surrounding air. In contrast, synthetic grass absorbs and retains heat from the sun, leading to much higher surface temperatures. This cooling effect makes natural grass more comfortable and safer for recreational activities during hot weather.
