Kinds of Ovules

Ovules undergo varied degrees of curvature during development. The position of micropyle with respect to the funiculus becomes different and constitutes the basis of classification of the ovules. Five basic types of ovules are known. These are: anatropous, orthotropous, hemi anatropous, campylotropous and amphitropous.
