Why are egg and sperm cells specialised?

Answer 1

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. =)

Answer 2

It is mainly due to the fact that the millions of sperm entered ito the vagina after ejaculation takes place the semen is released in the cervix. The semen then imeadiately coagulates so that the female retains the sperm

Answer 3

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.

Answer 4

Sperm cells have a long, thin tail to propel them cells to the egg. Masses of mitochondria provide the necessary ATP to make the journey. Nerve cells or neurones are coated in a myelin sheath to insulate and protect the cells Red blood cells have a bi-concave shape which increases their surface area to maximise oxygen uptake. They don't have a nucleus either, to further raise their potential capacity for oxygen uptake. White blood cells are able to either engulf pathogens, or secrete antibodies to kill them.

Answer 5

There are many types of white blood cells. - If you want the short general answer, it's that some release antibodies to stop the microbe/virus from causing any more damage, some get your body back to normal, some tackle bacteria and fungi whilst others tackle larger parasites. Job done. That is the Year 7/8 answer for you. If you want the year 4 answer, it is that they 'swallow germs'.

Answer 6

A sperm cell (gamete) is a specialised cell because it only performs one function: to fertilise an egg, and its structure relates to it's function. For example, the sperm cell's long tail helps it swim faster.

Answer 7

they have good legs for running to the infection

Answer 8

It is specialized because it takes away the bacteria that gets inside you otherwise that bacteria could harm you. Also there would be lots of white blood cells because they die away easily.
