Final answer:
The maximum cardinal temperature range for most plants is typically between 25-35 °C (77-95 °F), with exceptions for plants that grow in cooler habitats. Factors such as photosynthesis, respiration, and growth are influenced by temperature in plants.
Step-by-step explanation:
The maximum cardinal temperature range for most plants is typically between 25-35 °C (77-95 °F). This temperature range represents the optimum conditions for growth. However, there are exceptions, as some plants have maximum growths rates below 35 °C, which is typically seen in plants that grow in cooler habitats.
For example, certain flowering plants can adapt to temperatures well below freezing and tolerate temperatures above 40 °C. This adaptability allows these plants to survive in various environments.
The effects of temperature on plant activities, including photosynthesis, respiration, and growth, are influenced by temperature. As the temperature increases within the optimal range, plant growth and photosynthesis increase, but respiration increases more. As a result, the net photosynthesis declines, leading to a decrease in plant growth.
