The nucleus of an ovum does not divide in the same way as in typical somatic cells. Instead, during oogenesis, the ovum undergoes meiosis, where it completes the first meiotic division to form a secondary oocyte and a polar body. The secondary oocyte then arrests in metaphase II until fertilization occurs, after which it completes meiosis, resulting in another polar body and the mature ovum. Thus, the division of the nucleus in an ovum is primarily associated with the process of meiosis, rather than conventional nuclear division.
What else can I help you with?
DNA is found only in sperm and ovum?
No, DNA isn't just found in the sperm and ovum. DNA is found in the nucleus of all cells in the body.
Is a human ovum a prokaryote?
No, a human ovum is a eukaryotic cell. Prokaryotic cells lack a true nucleus and membrane-bound organelles, while eukaryotic cells have these structures. The ovum contains a nucleus with DNA and organelles like mitochondria that are characteristic of eukaryotic cells.
How many autosomes are in each ovum?
Each ovum contains 22 autosomes, which are the non-sex chromosomes. This is because during oogenesis, the egg cell undergoes a process called meiosis to divide the chromosomes evenly into four daughter cells, resulting in one mature ovum with half the number of chromosomes.
Why don't prokaryotic cells divide through mitosis'?
Mitosis is division of the nucleus, and prokaryotes don't have a nucleus
What does an OVUM look like under microscope?
An ovum, also known as an egg cell, is a large and nutrient-rich cell that contains a single set of chromosomes. When seen under a microscope, an ovum appears as a round cell with a distinct nucleus and cytoplasm. It is typically larger than other cells in the body and contains structures like mitochondria for energy production.
What does the nucleus do in the ovum?
it controls it
DNA is found only in sperm and ovum?
No, DNA isn't just found in the sperm and ovum. DNA is found in the nucleus of all cells in the body.
Is a human ovum a prokaryote?
No, a human ovum is a eukaryotic cell. Prokaryotic cells lack a true nucleus and membrane-bound organelles, while eukaryotic cells have these structures. The ovum contains a nucleus with DNA and organelles like mitochondria that are characteristic of eukaryotic cells.
What is needed for a zygote to form what is this process called?
Zygote is formed by the unification of an ovum and a sperm.Sperm provides the nucleus whereas the oven provides the cytoplasm of the zygote.Union of a sperm and a ovum is called fertilization and zygote formed in this way is diploid in nature.
Is a egg a female?
ovum ovum ovum
Why don't prokaryotic cells divide through mitosis'?
Mitosis is division of the nucleus, and prokaryotes don't have a nucleus

During asexual reproduction when does the cytoplasm divide?
after the nucleus divides:)
Why is the nucleus importance in a plant cell?
The nucleus is important because it contains the genetic material for our cells to divide and develop
Why is the nucleus important in the plant cell?
The nucleus is important because it contains the genetic material for our cells to divide and develop
Can a mature red blood cell divide?
No, mature red blood cells do not have a nucleus or organelles required for cell division. They are produced in the bone marrow from stem cells but lose their nucleus during development, making them unable to divide.
What are facts about an ovum?
its an ovum
