What is the production growth and maturation of an egg or ovum called?
Oogenesis is the process of producing an ovum (egg cell). Egg production begins and ends before birth. There is a series of processes that take place during the production of an ovum... for more detailed information on the entire process, take a look at this article. http://en.wikipedia.org/wiki/Oogenesis
What is contained in the cytoplasm of a female sex cell?
The cytoplasm of a female sex cell, or egg cell, contains organelles like mitochondria for energy production, cytoskeleton elements for structural support, and enzymes essential for cellular processes. It also contains nutrients necessary to support the development of the embryo after fertilization.
Which is the largest cell on the earth?
The EGG OF AN OSTRICH is the biggest cell in the world.
How would you describe the production of an ovum?
The production of an ovum, or egg cell, is called oogenesis and occurs in the ovaries of females. It involves a series of cell divisions and maturation processes that result in the development of a mature egg cell capable of being fertilized by a sperm cell. Ovulation is the release of a mature ovum from the ovary into the fallopian tube, where it can potentially be fertilized.
Why would placing a cell nucleus inside a nucleus- free egg cell enable the egg to begin dividing?
Placing a cell nucleus inside a nucleus-free egg cell enables the egg to begin dividing because the introduced nucleus carries the genetic information necessary for cell division. The nucleus contains the DNA that instructs the egg cell to start dividing and developing into an embryo. This process, known as somatic cell nuclear transfer, reprograms the egg cell to start cell division by activating the genes in the introduced nucleus.
How hormones affect egg production by the ovaries?
Hormones maintain a delicate balance in the body that makes the ovaries produce eggs. When this balance is affected by hormonal changes, egg production can be increased or diminished.
What is the benefit of uneven production of gametes in oogensis?
Uneven production of gametes in oogenesis results in the formation of one large egg cell and several smaller polar bodies. The larger egg cell contains most of the cytoplasm and organelles necessary for supporting early embryonic development, while the smaller polar bodies degenerate. This ensures that the developing embryo receives ample nutrients and cellular machinery from the egg cell.
How could the maturation of an egg cell be halted in the ovary?
The halt in egg cell maturation in the ovary can occur if the initial stages of meiosis are arrested. This can happen due to hormonal imbalances, genetic factors, or environmental influences. Without the proper signals or conditions, the egg cell will not progress through its normal development stages.
What does an egg contribute to the embryo that a sperm cell does not?
An egg contributes the majority of the genetic material needed for the embryo to develop, including the mitochondria for energy production. In contrast, a sperm cell provides only half of the genetic material necessary for embryo formation.
What is a hen's egg a cell or a group of cell?
A hen's egg is a single cell, specifically an ovum or egg cell, that is formed in the hen's ovary. It contains all the necessary components to potentially develop into a chick if fertilized by a sperm cell.
What is the purpose of the egg cell donor in cloning?
The egg cell donor in cloning provides the genetic material necessary for the creation of a clone. The nucleus of the donor egg cell is usually removed and replaced with the DNA of the individual being cloned, initiating the development of a genetically identical organism. The egg cell provides the necessary environment for the DNA to develop into a new organism.
How does light affect egg production?
Light plays a significant role in stimulating egg production in hens. Increasing daylight hours can trigger the release of hormones in the bird’s pituitary gland, which stimulates egg development and ovulation. Providing more hours of light can help maintain consistent egg production in hens.

What happens when a sperms cell and an egg all unite?
When a sperm cell and an egg cell unite they form a zygote which now has the DNA it needs to divide and form a new individual. The sperm cell and the egg cell have one half the amount of DNA necessary to form a new individual.
Glands that produce the egg cells and hormones?
Glands that produce the egg cells and hormones are the ovaries.
Ostrich egg equal to single cell?
Think of the ostritch egg as a chicken egg. The yellow of the chicken egg is the nucleus, the white part is the ctyoplasm and the shell is the cell membrane/cell wall. So now an ostritch egg is just a bigger version of a chicken egg. GET IT?
Which contains more cytoplasm and needed chemicals egg or sperm cell?
An egg cell contains more cytoplasm and needed chemicals than a sperm cell. This is because an egg cell is larger and contains all the necessary organelles and nutrients to support early development after fertilization. Sperm cells are specialized for motility and delivering genetic material to the egg.
