The ovule is

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

Answer 1

The correct option is B

Amphitropous
Campylotropous ovule
The body of a campylotropous ovule is curved such that the micropyle and funicle lie at the same pole near each other.

Amphitropous ovule
In an amphitropous ovule, the body of the ovule and the embryo sac are curved so that the hilum, chalaza and micropyle lie in close proximity. The embryo sac forms a horseshoe shape.

Orthotropous ovule
An orthotropous ovule lies straight in the ovary and has a straight funicle which is in the same line with the micropyle and chalaza.

Anatropous ovule
Anatropous ovule is inverted and the micropyle lies close to the hilum, facing the placenta. The micropyle and chalaza lie in a vertical line.
