Before revision:  We present separate stability constraints for the mechanical part of the one-dimensional morphoelastic model and stability constraints for the chemical part of the one-dimensional morphoelastic model. Stability results are developed for both the continuous and (semi-) discrete problems.
After revision:  We present separate stability constraints for the mechanical part of the one-dimensional counterpart of this morphoelastic model, for both the continuous and (semi-) discrete problems.
