Re: Are nuts wood?

Hi there! No, nuts are not wood. Nuts are fruitlike. The outer layer (the 
woody-like part) is heavily lignified and this gives the nut it's hardness. 
Inside the nut  is the  seed  to the plant. 
     Wood is the  product of secondary  growth in a plant. It consists
of xylem and phloem and it's  functional purpose is to carry water and 
sugar and nutrients to plant parts.  It too is heavily lignified and  this 
gives the wood it's hardness. However, wood's structural and functional 
purposes are completely different from a nut's. As well, a nut's outer 
layer is composed of entirely different cell types than wood's and it's 
function is solely to protect the seed.
