Question

Which of the following statements is incorrect with respect to a typical anatropous ovule?

• A. The stalk of the ovule is called funicle.
• B. Micropyle is situated opposite to the basal part of the ovule.
• C. Hilum is a small opening on the surface of an ovule.
• D. The mass of cells enclosed within the integuments is called nucellus.

Answer 1

The correct option is C Hilum is a small opening on the surface of an ovule.

Hilum is not a small opening on the surface of an ovule. Hilum is the region in which the body of the ovule fuses with the funicle. Infact, micropyle is the small opening on the surface of an ovule. It is the only region where the ovule is not covered by the integuments.
Hence option 'c' is incorrect.

The ovule is attached to the placenta within the ovary by means of a stalk called funicle.

The micropyle is situated opposite to the basal part of the ovule called chalaza.

The diploid nutritive tissue inside the ovule is called nucellus.
