• 1. why does photosynthesis rate maximum at 2-3pm? intensity of sunlight as sun is at its zenith + warmest in afternoon - enzyme and metabolic activity, stomata opened
  2. why does rate of respiration not change as much throughout the day? to meet energy requirements (growth, repair, metabolism) vs ph needs light
