In anatropous ovule, micropyle lies _________.


Open in App
Solution

Ovule:

  1. Ovules are present inside the ovary.
  2. It is the region where female reproductive cells are enclosed.
  3. The ovule is found at the bottom of the carpel (female reproductive organ vase-like in structure).
  4. The top of the carpel has a neck and an opening for the pollen to fall known as stigma.
  5. After fertilization, the ovule of the ovary gets converted into seed.
  6. The ovules can grow perpendicular to the funicle, thus the ovule seems to lie on its side.
  7. An anatropous ovule is an ovule that has a micropyle in the position which is adjacent (near) to the funicle (filamentous stalk attaching the ovule to the placenta) base.
  8. Anatropous ovule is the most common ancestral ovule found in angiosperms.

Micropyle:

  1. Micropyle is the small opening at the ovule through which the pollen tube enters the ovary.
  2. The chalaza is known as the basal part of the ovule where the nucellus and integuments of the ovule attach, hence it is known as the chalazal end.
  3. The junction where the ovule fuses with the stalk-like funicle is known as the hilum.
  4. When the chalaza and micropyle lie in the straight line but the hilum is at 90 °to the micropyle then the micropyle is in close association with the funiculus.
  5. The ovule body might get turned 180° which can also make the micropyle come close to the funiculus.

Final answer: In anatropous ovule, micropyle lies in a straight line with funicle.
