Match the following factors with their impact on the rate of photosynthesis:

Light wavelength = Affects the rate and efficiency of photosynthesis Amount of water = Influences the overall rate of photosynthesis Red or blue light = Results in a faster rate of photosynthesis Oxygen level = Indicates whether the plant needs to release excess oxygen Signup and view all the answers

Match the following substances with their role in photosynthesis:

Carbon dioxide (CO2) = Used as a raw material for glucose production Water (H2O) = Supplies hydrogen ions and electrons for glucose formation Glucose (C6H12O6) = The primary product of photosynthesis Oxygen (O2) = Released as a byproduct during photosynthesis Signup and view all the answers
