PROTEIN IN PLANTS AND ANIMALS 



PROTEIN IN PLANTS 



From the above results we can see that the protein in seeds 

 is greater than in straws. In the woody or older parts of the 

 plant very little protein is found. The legumes are richer in 

 protein than the grasses. Grass hay and straw contain much 

 more protein than roots. The protein in grains is found largely 

 in the germ and that portion closely surrounding it. 



DISTRIBUTION OF PROTEIN IN THE CORN PLANT 



This distribution of protein in corn is interesting. The bran 

 is the outer covering of the corn grain and is for protecting the 

 seed, and is therefore low in protein. The outer coverings of 

 other seeds as oats, rice, cotton, etc. also contain less protein than 

 the other parts of the seed. The germ, or embryo plant, is com- 

 paratively rich in protein for it is this part of the seed that must
