Question

Growth is primarily affected by two climatic factors ...........................

• A. Light and temperature
• B. Temperature and relative humidity
• C. Light and wind
• D. Rainfall and temperature

Answer 1

The correct option is A Light and temperature

Growth in plants is affected by a number of environmental factors. The most important ones are light and temperature. This is because plants are autotrophic organisms and use light energy to produce their food. Since plants are living organisms, their metabolism requires ambient temperature and pH. This is because all the metabolic reactions are catalyzed by enzymes.
