No. The nucleus stores most of the genetic material--DNA (and the messenger RNA that is sent out of the nucleus into the cytoplasm of the cell to be translated)--except for the DNA that's in the chloroplasts and the mitochondria. Plants are autotrophic, meaning they are "self feeding", and the products of photosynthesis--photosynthate, all those sugars, all those carbohydrates--provide the food for the plant, along with the nutrients and such that the plant takes up from the roots because they're dissolved in water, and the products of photosynthesis allow the plant to grow and provide the energy for the nutrients and such to work within the plant. But because proteins require nitrogen to be made, and nitrogen is taken up from the plant through the soil (NO3- or NH4+), plants don't just get food from the sugars created in photosynthesis. You could say that the nucleus provides the pattern for the ribosomes to be made, though, (in the DNA, to be transcripted into messenger RNA, to be translated into a polypeptide chain) and ribosomes are where the proteins are synthesized.
