A sperm cells particular function is to fertilise an egg cell
How does a sperm cell become Specialised?
Sperm Cells are specialised in a number of ways. They
have an Undulipodium (tail) which moves
by energy generated by many mitochondria and propels the cell. The head of the cell contains an Acrosome, which is a specialised Lysosome that releases enzymes so that the Sperm Cell can penetrate the Ovum Coat of the Egg.
How are sperm cells Specialised GCSE?
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. Sperm are the smallest cells in the body and millions of them are made.
What is unique about a sperm cell?
The sperm cells have
only 23 chromosomes
, or half of the usual number. When a sperm cell unites with the ovum, which also has 23 chromosomes, the resulting 46 chromosomes determine the offspring's characteristics. The sperm cells also carry the X or Y chromosome that determines the sex of the future child.
How is an egg cell Specialised?
Although an egg can give rise to every cell type in the adult organism, it is itself a
highly specialized cell
, uniquely equipped for the single function of generating a new individual. The cytoplasm of an egg can even reprogram a somatic cell nucleus so that the nucleus can direct the development of a new individual.

Is it healthy to eat sperm?
Is it Safe to Swallow Semen?
The ingredients that make up semen are safe
. Some people have had severe allergic reactions to it, but this is very rare. The biggest risk when swallowing semen is getting a sexually transmitted infection.
What is inside a sperm cell?
The mature sperm cell (spermatozoa) is 0.05 milliliters long. It consists of
a head, body and tail
. The head is covered by the ac cap and contains a nucleus of dense genetic material from the 23 chromosomes. … Sperm swim at a rate of about 3mm (0.12 inches) per minute.
Where is the sperm cell located?
Sperm develop in
the testicles
within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells.
What are some Specialised cells?
| Specialised cell type Animal or plant cell? | Skeletal muscle cell Animal | Neuron (nerve cell) Animal | Red blood cell Animal | Sperm cell Animal |
|---|
What are the Specialised cells?
Nerve cells, blood cells, and reproductive cells
are examples of specialized cells. … Reproductive cells include the sperm cell and egg cell. These cells have special features that allow them to come together and create a new organism that will grow and create specialized cells of its own!
How many egg cells does a woman have?
At birth, there are
approximately 1 million eggs
; and by the time of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman's reproductive lifetime. Fertility can drop as a woman ages due to decreasing number and quality of the remaining eggs.
What are the 2 types of cell?
Cells are of two types:
eukaryotic, which contain a nucleus, and prokaryotic cells
, which do not have a nucleus, but a nucleoid region is still present. Prokaryotes are single-celled organisms, while eukaryotes can be either single-celled or multicellular.
What are three Specialised cells?
| Specialised cell type Animal or plant cell? | Skeletal muscle cell Animal | Neuron (nerve cell) Animal | Red blood cell Animal | Sperm cell Animal |

Why is a red blood cell Specialised?
Red blood cells transport oxygen around the body. They are
specialised to carry oxygen because
they: contain large quantities of a protein called haemoglobin , which can bind oxygen. … have a biconcave disc shape, which maximises the surface area of the cell membrane for oxygen to diffuse across.
