Essay On Ovum

Ovum Cell Research Paper The ovum cell is one of the most important cells in all living organisms. Most ova are unicellular because they are only one cell at first but becomes multi cellular once fertilized by the sperm and begin dividing. However, in other organisms, such as protists, they can start off as multi cellular as well. The ova is the female gamete produced by the female reproductive system and joins together with the sperm, the male gamete, during fertilization to form the embryo. Gametes are haploids which is the only type of cell that contains only one set of chromosomes. Ova are produced by many living organisms, such as animals, protists, fungi, and flowering plants and ferns. In animals, they are produced
It also provides nutrients for the embryo once it is formed until it sinks into the uterus where the placenta can take over. In the human body, the ovum is about the size of a sesame seed, or approximately 0.12 mm in diameter. The reason why it is so large is because it contains all organelles, materials, and nutrients for the growth and development of the embryo as well as a layer of padding which protects valuable information in the nucleus. So what kind of organelles do ovum cells have and what are their functions? Nucleus
The nucleus controls the entire ovum cell and it contains most of the genetic material in the form of chromosomes. This is where the genes are situated when the sperm cell enters the ovum. Both the egg and the sperm have half the number of chromosomes of a regular cell. For example, in a human reproductive system, the sperm and the egg have 23 chromosomes, so once they combine during fertilization and create the embryo it will have the normal 46 chromosomes. The human baby will also receive its genetic information and inherit traits from its mom and dad from the nucleus.
