Question

The most common type of ovule is

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

Answer 1

The correct option is C Anatropous

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

•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.

•Anatropous ovule is the most common type of ovules, which occurs in more than 80% of angiospermic families. The body of ovule is rotated by 180° and micropyle comes near to the funiculus. Chalaza and micropyle lie in the straight line but hilum is at 90° to micropyle.

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

So, the correct answer is C.
