Morphology
This is a straightforward adjective + noun combination: 'anatropous' denotes an inverted form and 'ovule' denotes the seed/egg structure, so the phrase simply means an ovule that is inverted. The meaning is directly compositional and follows a standard modifier pattern rather than an idiomatic shift, so learners who know both constituents can infer the MWE's meaning.
Etymology
Anatropous ovule describes an ovule bent all the way back on its little stalk, so the tiny opening, the micropyle, points toward the plant's seed tissue called the 'placenta'. That strong picture of an ovule 'turned back' explains why the term means an ovule completely inverted with its opening near the 'placenta'.
