Question

Body of the ovule is straight but at right angles to the funicle. It is

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

Answer 1

The correct option is C Hemitropous

•Orthotropous ovule is the simplest and primitive type of ovule. In this type of ovule, micropyle, chalaza and funiculus lie in one vertical plane.

•Campylotropous ovule- In this type of ovule, the length of funiculus becomes increased and it covers the whole ovule.

•Hemianatropous ovule- The body of ovule is turned through 90° and micropyle and chalaza lie in a straight line but funiculus is at right angle or 90° with both these two.

•Amphitropous ovule- The body of ovule gets curved along with the embryo sac in such a way that it becomes horseshoe-shaped.

Thus, in Hemianatropous ovule, the body of ovule is straight as it doesn't get curved and is turned to 90° such that it is at right angle to the funiculus.

So, the correct answer is C
