Morphology

orthotropous + ovule

The adjective 'orthotropous' explicitly describes an orientation ('straight with micropyle at apex'), so when combined with 'ovule' the phrase plainly denotes an ovule having that orientation. Although technical botanical vocabulary, the meaning is directly compositional (adjective modifying noun) and therefore predictable to a learner who knows both constituent meanings.

Etymology

The noun orthotropous ovule gets its name from its straight, upright shape: imagine a tiny egg that stands straight so the little opening, the micropyle, is at the top. That's why the term means an ovule that is 'completely straight' with the micropyle at its 'top'.
