Ovum is produced by _____.

An ovum, also known as an egg cell, is the female reproductive cell. It is produced in the female reproductive system through a specific process.

The production of an ovum occurs in the ovaries – the female reproductive organs responsible for producing eggs and reproductive hormones. The process by which ova (plural of ovum) are produced is called oogenesis.

Oogenesis is the process of formation, development, and maturation of an ovum in the ovaries. It begins before a female is born and continues until menopause. Oogenesis involves several stages: oogonium, primary oocyte, secondary oocyte, and ovum.

Here is a breakdown of the stages of oogenesis: 1. Oogonium: These are the immature egg cells that are present in the ovaries even before a girl is born. There are around 1 to 2 million oogonia by the time a girl reaches puberty. 2. Primary oocyte: At puberty, one oogonium in each menstrual cycle starts maturing into a primary oocyte and enters the first phase of meiosis, but gets arrested in the prophase I stage. 3. Secondary oocyte: During ovulation, one primary oocyte is released from the ovary and finishes meiosis I, producing a secondary oocyte and a smaller polar body. 4. Ovum: If the secondary oocyte is fertilized by a sperm, it quickly completes meiosis II and becomes a mature ovum, ready to form a zygote which eventually develops into a fetus. To answer the question, ovum is produced by the process of oogenesis within the ovaries.
