Answer:

Megasporangia (female sporangia) produce megasporocytes (megameiocytes) that yield megaspores. The sporangia may be borne in specialized structures such as sori in ferns, cones (strobili) in some pteridophytes and most gymnosperms, or flowers in angiosperms.

Answer:

Megasporangium or Ovule is the structure inside ovary where megaspore formation takes place.

The internal structure of the Ovule consists of the following parts:

Funicle: Stalk that attached ovule to placenta

Hilum: Junction between ovule & funicle

Integuments: One or many protective envelopes around ovule

Micropyle: A small opening at the tip of integuments

Chalaza: Basal part of ovule

Nucellus: Mass of cells enclosed within integuments used for food storage

Embryo sac: Female gametophyte located in nucellus

MEGASPORE MOTHER CELL(MMC):

•a diploid cell in plants that undergoes meiosis to create four haploid megaspores

•The megaspore mother cell arises within the megasporangium tissue.

•These cells resides within the ovule that is surrounded by integuments
