Question

An experiment showed that seeds from a certain plant species germinate best at a temperature of 25°C when tested in a range from 0°C to 50°C. It was concluded that variations in temperature had a direct effect on the success rate of the germination of the seeds. Which statement gives a reason for this conclusion?

A. Temperature affects the enzyme's ability to function properly.
B. Temperature affects the carbohydrate's ability to function properly.
C. Temperature affects the process of fertilization.
D. Temperature affects the process of photosynthesis.

Answer 1

Temperature affects the enzyme's ability to function properly, which is why variations in temperature have a direct effect on the success rate of seed germination.

Step-by-step explanation:

The experiment showed that variations in temperature had a direct effect on the success rate of the germination of the seeds. In this case, the reason for this conclusion is that temperature affects the enzyme's ability to function properly. Enzymes are biological catalysts that facilitate chemical reactions, including the breakdown of stored energy in seeds during germination. Temperature influences the activity and functionality of enzymes, and at 25°C, the enzymes involved in seed germination are optimally functional.
