The ovule of an angiosperm is technically equivalent to

  1. megasporangium
  2. megasporophyll
  3. megaspore mother cell
  4. megaspore.

Answer

(1) megasporangium

Solution

As per NCERT, the ovule is a small structure attached to the placenta by the funicle; the megasporangium of angiosperms is the ovule, in which the megaspore mother cell forms megaspores.

⇒ The carpel (pistil) is the megasporophyll, and the megaspore mother cell and megaspore are cells inside the ovule.

∴ The ovule is technically equivalent to the megasporangium.
