What is the process that produces sex cells?
Meiosis < hope it helps you along your biological way (: Eggs (also called ova or oocytes), and sperm are called "Sex Cells". A single egg cell is called an ovum, and a single sperm cell is called a spermatozoa.
Is a zygote part of the female reproductive cell?
A zygote is formed from the egg cell contributed by the female parent and an sperm from male parent. The fertilized egg is called a zygote, therefore, zygote is definitely a part of female reproductive cell.
Why is it neccessry to reduce the chromosome number of gametes but not other cells of an organism?
Gametes are sperm and egg cells. When the sperm fertilizes the egg, their genetic material is joined to form a new cell called a zygote. Because both the sperm and egg cells have half the number of chromosomes as in normal body cells, the zygote will have the full number of chromosomes as in normal body cells.
During the process of fertilization which step happens first?
It is hard to say which step happens first in the process of human fertilization. The process leading up to it is usually slow. A man and a woman smile at each other. That is actually the first step. They get to know each other. The process goes on and on. A man grabs hold of a woman. Neither one has clothes on. He puts his penis in her vagina. Both push back and forth. Eventually, with them breathing hard, he ejaculates semen. Sperm work their way out from her vagina, through her uterus into her fallopian tubes. Meanwhile, her ovaries prepare an egg. It has a full set of chromosomes. It loses half of them. Unlike ordinarily cell division, only the nucleus divides. The egg cell ejects the nucleus called a polar body. The ovary ejects the egg. little cilia move the egg to the fallopian tubes. There it meets the sperm. The sperm breaks through the surface of the egg. The surface becomes hard so no more sperm will break through. The sperm swims through the egg until it reaches the nucleus. There it deposits its chromosomes. The chromosomes in the nucleus break apart and then reassemble. At that point the chromosomes of the new individual exist in the form the new person will have them the rest of his or her life. Which step happened first?
What are two main types of gametes?
the female egg and male sperm.
Process of uniting an egg with a sperm?
The process of uniting an egg with a sperm is called fertilization. It occurs when a sperm cell penetrates the outer layer of an egg cell and fuses with the egg's nucleus, forming a zygote. This marks the beginning of a new organism's development.
What is process of forming male gametes called?
It is still called meiosis, except that instead of an egg you end up with a sperm cell.
What is the process called in which the sperm and egg unite?
It is called Fertilization.
What is the process when sperm joining the egg called?
FERTILIZATION
What is the process of uniting of the sperm and egg called?
Fertilization
When the sperm meats with the egg what is this called?
Fertilization is the process describing the union of the sperm cell and the ovum.
How does sperm fertilize an egg?
Sperm fertilizes an egg through a process called fertilization. During sexual intercourse, sperm is released into the female reproductive system and swims towards the egg. When a sperm reaches the egg, it penetrates the outer layer of the egg and releases its genetic material. This genetic material combines with the genetic material of the egg, forming a new cell called a zygote. This zygote then begins to divide and develop into an embryo, which eventually grows into a baby.
What happens when the sperm cell reaches the egg cell?
When the sperm reaches the egg, they fuse together forming one cell and multiplying creating what is called the fetus.
How does sperm fertilize an egg to initiate the process of conception?
During fertilization, a sperm cell penetrates the outer layer of the egg and releases its genetic material. This genetic material combines with the genetic material of the egg, forming a new cell called a zygote. The zygote then begins to divide and develop into an embryo, initiating the process of conception.
What do you call it when a sperm cell units with a egg cell?
When a sperm cell unites with an egg cell, it forms a zygote. This process is called fertilization.
The process in which a sperm cell fuses with an egg in the ovary called?
fertilization
What is the process called when the egg and sperm combint the contents of their nuclei?
fertilization
