Question

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

• A. Anatropous
• B. Orthotropous
• C. Hemitropous
• D. Campylotropous

Answer 1

The correct option is C Hemitropous

An ovule which becomes curved so that the nucellus and embryo sac lie at right angles to the funicle is a hemitropous ovule. The body of the ovule is placed transversely at right angles to the funicle and the micropyle and chalaza lie in one straight line in hemitropous ovules.

Anatropous ovule - a completely inverted ovule turned back 180 degrees on its stalk.

Orthotropous ovule - a completely straight ovule with the micropyle at the apex.

Campylotropous ovule- The body of the ovule is curved and bent around so that the micropyle and chalaza do not lie in the same straight line.

Thus, the correct answer is Hemitropous - option (c).
