Thermal Influence on Tetrahymena Growth: Comparative Analysis Across Optimal, Marginal, and Extreme Temperature

Abstract

In this experiment, we studied the influence of temperature on the growth rate of Tetrahymena thermophila (T. thermophila), a unicellular organism with profound historical significance in biology and complex ties to ecosystem dynamics. The experiment entailed cultivating T. thermophila at three distinct temperatures (25°C, 33°C, and 40°C) in separate incubators, with two-hour sample collections over two days.

We predict that T. thermophila exhibits different growth rates under varying thermal conditions. The statistical analysis indicates no significant temperature differences (p-value = 0.7038 > 0.05) among different temperature treatments and thus denied our original hypothesis. We conclude that experimental errors, such as inaccurate sampling or statistical error, may lead to this result.
