What is on a sperms tail?
A sperm's tail, also known as a flagellum, is responsible for propelling the sperm forward toward the egg during fertilization. It is made up of proteins and microtubules that generate the whip-like movement required for the sperm to swim.
How is a sperm cell good at its job?
The sperm cells (spermatozoa) shape and structure makes it a specialised cell. Its tail (flagellem) enables it to swim and move easily to reach and fertilise the female egg. There are many mitochondria within the body of the cell providing it with the energy to enable it to swim. Within the head of the sperms cytoplasm a vacuole containing enzymes is present so that it can digest its way through the ovum to fertilise it.
The Function of Flagellum?
Flagellum are used to propel microscopic organims like, bacteria. Some microscopic organisms have many some have just one or two. But much like the fins and tails of fish through the proper function of flagellum the organism gets where it needs to go.
Why are egg and sperm cells specialised?
It is specialised by being a long, thin cell that enables it to carry electrical messages (nerve impulses) around the body through travelling along the "axons" (thin, long bit in middle knows as "nerve fibres") from your brain or spinal cord to one of the muscles. Once the impulse gets to the muscle, the muscle contracts. =)
