In higher plants much of the product of photosynthesis 

 must be transported to a nonphotosynthetic part of the plant. 

 This requires that higher proportions of easily transported 

 molecules such as sucrose are formed (4). In all higher plants 

 that have been studied, however, there is appreciable direct 

 photosynthesis of amino acids and fats, not just carbohydrates.
