Pardon my disagreement...
Photosynthesis is the process plants (and some animals) use to fix carbon used to build the structure of their bodies. During photosynthesis carbon dioxide is consumed, the carbon from the CO2 is fixed to form organic molecules for building the organisms structure, and providing sugars used as metabolites for energy, and oxygen is exhaled.

If photosythesis is not occuring, then there is no carbon fixation, and consequently no growth. Consequently, growth DOES mean photosynthesis is occuring.
