The gardener's observation that rye grass grows faster than Zoysia grass, despite equal environmental conditions, suggests a genetic influence on grass growth rates. This conclusion aligns with the idea that genes play a role in determining growth characteristics in plants.
Based on the information provided, the conclusion that can be drawn about the growth rate of grass is:
A. The growth rate of grass is affected by the genes of the grass.
The gardener's observation that rye grass grows at a faster rate than Zoysia grass despite receiving equal amounts of water and sunlight suggests that the difference in growth rate is likely influenced by genetic factors inherent to each type of grass. Genetic characteristics play a crucial role in determining various traits, including growth rate, in plants. While environmental conditions, such as water and sunlight, can impact growth, the consistent difference observed in the growth rates of rye grass and Zoysia grass points towards a genetic influence on their respective growth rates.
