Solution

The correct option is B Orthotropous
Orthotropous ovule
  • The orthotropous ovule lies straight in the ovary and has a straight funicle which is in the same line with the micropyle and chalaza.
  • Thus the body of the ovule, embryo sac, micropyle and funicle, all lie in one vertical plane.
