Why male egg cell has a long tail?

Why male egg cell has a long tail?

Tail allows the sperm to become motile, hence helps the sperm to reach ovum which is larger in size and nonmotile.

Why do sperm have a tail like structure?

A new study focuses on the development of the sperm tail, the structure that enables sperm cells to swim and is therefore critical for male fertility. By beating their tails, sperm cells swim to the female reproductive cell (oocyte) and fertilise it.

Why do sperm cells have a long tail and a streamlined head?

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.

Why do sperm have tails Class 10?

Since the sperm needs to travel inside the female reproductive system and enter the egg, it has a tail. Tail helps the sperm to move forward (like a snake) instead of moving in circles.

Why does a sperm cell have lots of mitochondria?

The acrosome in the head contains enzymes so that a sperm can penetrate an egg. The middle piece is packed with mitochondria to release energy needed to swim and fertilise the egg. The tail enables the sperm to swim.

What is the function of a sperm cell ks3?

Sperm are the smallest cells in the body and millions of them are made. The cytoplasm contains nutrients for the growth of the early embryo. The haploid nucleus contains the genetic material for fertilisation. The cell membrane changes after fertilisation by a single sperm so that no more sperm can enter.

What is the function of tail?

Many land animals use their tails to brush away flies and other biting insects. Some species, including cats and kangaroos, use their tails for balance; and some, such as monkeys and opossums, have what are known as prehensile tails, which are adapted to allow them to grasp tree branches.
