Tail allows the sperm to become motile, hence helps the sperm to reach ovum which is larger in size and nonmotile.Aug 31, 2017
Why does sperm have a long tail?
The tail gives the sperm cell movement. It whips and undulates so that the cell can travel to the egg. Following sperm deposition in the female reproductive tract, activation of tail movement is suppressed until the sperm is carried to within a relatively short distance of the egg.
Why do sperm cells have a long tail and a streamlined head?
Sperm cells have streamlined head and long tails which helps it to swim to towards the egg cell. Structure: Large surface area to hold lots of haemoglobin so oxygen can be carried. Has no nucleus to make room for more oxygen.
How does the shape of a sperm cell help its function?
Streamlined body - The sperm has a streamlined body that allows it to move rapidly to reach the target egg cell. For instance, the head has a tapering apex which helps reduce drag as the cell travels in the female reproductive tract.
What is the tail of a sperm cell called?
flagellumThe flagellum, also called the sperm “tail”, is a slender lash-like appendage that protrudes from the cell body. By beating their tails, sperm cells swim to the female reproductive cell (oocyte) and fertilise it. A bundle of microtubules that span the entire length of the tail is critical for flagellar beating.
Why does the male egg cell has a long tail?
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.
What does it mean when a sperm has two heads?
duplicate spermWhen the sperm has two heads, it is called a duplicate sperm, a condition linked to exposure to toxic chemicals, heavy metals like cesium, smoke or high prolactin hormone in the male. Large swollen midpiece or sperm neck may be related to defective mitochondria, the energy-making parts of the sperm cell.
Why does a sperm cell have enzymes in its head?
Normal sperm cells have an oval-shaped head with a cap-like covering called the acrosome. The acrosome contains enzymes that break down the outer membrane of an egg cell, allowing the sperm to fertilize the egg.
Why do sperm cells have lots of mitochondria?
The sperm cell needs a lot of energy to reach the egg cell and therefore contains many mitochondria. So, now we know that the correct answer choice is (A). Sperm cells contain many mitochondria to provide them with energy needed for movement.
