Notifrealizit Takes Place In The Ovary When The Sperm Cell Unites With The Egg Cell.

NOTIFREALIZIT takes place in the ovary when the sperm cell unites with the egg cell.

 

Answer:

It takes place when a sperm cell unites with the egg cell

When the sperm cell finally reaches the egg cell, the plasma membranes of the two cells fuse together and the sperm releases its genetic material into the egg. At this point, fertilization has occurred, but were not done yet! Fusion also triggers the cortical reaction.

People are reproducing themselves through their sperm cells and egg cells. When a sperm cell unites with an egg cell to form a zygote. The process of this is called the ovulation and fertilization. Where it is possible to form another life from it.

Although it is happening every hour of every day, all over the world, the story of egg meeting sperm is still a tale worth telling. Millions of candidates set off on a long and perilous journey with a single target at the end, and if the candidates reach their target, something completely unique is created. But before we get to the end, let's take a closer look at the journey.

Hundreds of millions of sperm vie for a single egg cell. The sperm cells are streamlined in design for this purpose: a long tail to help them move, lots of mitochondria to power that movement, genetic information to pass on, and enzymatic proteins to get into the egg cell. The proteins are stored in a cap at the front of the sperm known as an acrosome - this is the part that first contacts the egg. The tail is called a flagellum, and it uses the energy made by the mitochondria to move the sperm forward. Flagella use a lot of energy, so they're kept dormant until sperm enter the vagina. Sperm are haploid; they contain one set of 23 chromosomes. They are created by the cellular division process known as meiosis, which creates 4 sperm from a single germ cell. They're also very small, only about 50μm long. Sperm are ejaculated in semen, a basic fluid with a pH of about 7.4.

short :

The sperms' target, is the egg. Since it is so much bigger than sperm, the egg is the source of cytosol and organelles,particularly mitochondria, for the future zygote

My Answer :

other sperm contributions to the egg. The egg lacks centrosomes and thus cannot divide without the critical contribution of centrosomes from the sperm
