An ovule which becomes curved so that the nucellus and embryo sac lie at right angles to the funicle is:

Step-by-step solution

Ovules have been separated into six categories based on their shapes: Orthotropous (Atropous): Ovules is straight so that the chalaza, the funicle and the micropyle are all aligned. Anatropous: Ovules become completely inverted during development so that the micropyle lies close to the hilum. Hemi-anatropous: Ovules becomes at a right angle in relation to the funicle. Campylotropous: ovule is bent and the alignment between the chalaza and micropyle is lost. Amphitropous: ovule is very much curved that the embryo sa
