Options

A. Hemitropous
B. Orthotropous
C. Anatropous
D. Campylotropus

Answer

C

Explanation

Ovules are of 6 types :
1. Orthotropous (Atropous) ovule
`**` Orthotropous ovule is the most primitive type ovule.
`**` Ovule is straight and Micropyle, chalaza and funicle lies in a straight line or present at `180^(@)` or in one vertical plant.
e.g. : Most of gymnosperms like Cycas and primitive angiosperms like Nelumbo and Polygonum.
2. Anatropous ovule
`**` Anatropous ovule is the most common (82 % angiosperms) and most advanced type of ovule.
Ovule is inverted.
`**` Micropyle and chalaza lies in a straight line.
`**` Micropyle and funicle lies close to each other.
e.g. : Asteraceaee (most advance dicot family) and Solanaceae.
3. Hemitropous (half-inverted) ovule
`**` Micropule and chalaza lies in a straight line but both lies at `90^(@)` or perpendicular to funcile.
e.g. : Primulaceae and Rannunculaceae.
4. Campyotropour (body curved) ovule
`**` Body of ovule is curved.
`**` Embryo sac less curved and appears kidney shaped.
e.g. : Capsella and Pea.
5. amphitorpous ovule
`**` Both ovule and embryo sac curved and appears horseshpe shaped.
e.g. : Papaveraceae, Alisma
6. Circinotropous ovule
`**` Funicle coiled around the ovule.
e.g. : Opunia.
