The anatropous ovule type is the most common in the angiosperms and is
presumed to be ancestral for the group. An orthotropous ovule is one in which no
curvature takes place during development; the micropyle is positioned opposite
the ...

Flower Seeds: Biology and Technology
Ovule types: A - anatropous; B - orthotropous. Integuments ovules are unitegmic (
i.e. have only one integument). The nucellus appears to play a role in nutrient
transfer between the mother plant and the developing embryo sac (Rangan and ...

A Text Book Of Practical Botany 2
In this type, the nucellar protuberance is at first in the same line as the axis, but
the rapid growth on one side makes it anatropous. The curvature continues till the
ovule has turned over completely with the micropylar end again pointing upward,
...

These are known as orthotropous, anatropous, amphitropous, campy lotropous,
hemianatropous and circinotropous ovules (Plate 10, Figures 1-6). In
orthotropous type, the micropyle and the funiculus are in the same line. In
anatropous type ...

Seed Development and Germination
Generally speaking three types of ovules can be recognized- Anatropous ovules
are the most common ones. In this case the ovule during its development
undergoes a curvature of about l 80°. By this process the nucellus and the
integuments ...
