Solution

An ovule is called orthotropous when its chalaza and micropyle are in an opposite direction on a straight line.

Explanation:

In an orthotropous ovule, the ovule is straight and upright with the micropyle, chalaza, and funicle aligned in one straight line. This is a simple, linear arrangement found in some plants like Polygonum.
