1. Regarding different or dissimilar forms: The heteromorphic existence in different phases at different stages of life, like insects that undergo complete metamorphosis.

Heteromorphic forms can take place at different times or at different stages of the life cycle of a plant having an alternation of vegetatively dissimilar generations.
2. A situation in which there is a replacing of missing pieces by new parts which are different from those that have been lost: The broken jug went through a heteromorphic process when it was repaired with pieces of material from a flower pot.

1. In biology, having a different appearance; differing in shape, size, or structure; such as, heteromorphic sex chromosomes. 2. In biology, taking different forms at different stages of a life cycle.
3. In medicine, characterized by an atypical form or forms.
4. Differing from the standard form in size or structure: heteromorphic chromosome pairs.

Deviating from the normal, perfect, or mature form; having different forms at different stages of existence, or in different individuals of the same species; applied especially to insects in which there is a wide difference of form between the larva and the adult, and to plants having more than one form of flower.
