The purpose of reproduction is to ensure the continuation of a species. Animals have evolved a number of mechanisms to ensure variability and assortment in a population. The most widespread of these is sexual reproduction between male and female gametes.

Fertilization may be either external or internal. Aquatic and amphibian animals usually fertilize externally, using water as a medium in which the sperm swims to the egg. Terrestrial animals normally fertilize internally.

The processes of spermatogenesis and oogenesis produce haploid sperm and eggs in specialized organs called testes and ovaries.

These gametes are produced from germ cells which are separated early in the development of the embryo.

The reproductive organs are designed to manufacture and store the gametes as well as to allow the act of mating.

Three sets of glands in the male add nutrients and enzymes to sperm that help the sperm move through the vagina into the uterus where fertilization takes place.

The uterus is the place where the egg will implant and grow into the embryo - and eventually the infant ready to be born.

Male and female reproductive systems are under the control of a group of hormones, and the hypothalamus is the main center for this regulation. The female reproductive system of humans and other primates follows a menstrual cycle.

Fertilization between male and female gametes occurs in animals from jellyfish to humans. The same basic mechanism of sexual reproduction applies in every case.

But we should also note that as animals have evolved into more complex forms, reproductive systems have also evolved into complex anatomical structures. Hormonal control has become a vital component of the processes involved in vertebrate reproduction, and is also the basis for the most reliable method of birth control.

In the human body and in that of animals, there are 2 types of reproductions:

Sexual reproduction and asexsual reproduction those are the two most important types of reproductions.

Sexual reproduction: we can find this reproduction only in human beings. Why?. Because humans reproduce through sexual intercourse. When a man and a woman have sexual intercourse, it is most likely that there is a baby in the woman's womb and the world will reproduce little by little. Such is sexual reproduction.

Asexual reproduction: Asexual reproduction does not involve sex cells or fertilization. Only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information. As a result, the offspring are genetically identical to the parent and to each other. They are clones.

Example of sexual reproduction:
Humans
Mamals animals

Example of asexula reproduction:
Animlas like: Frog, turtle etc.

Write your summary of 70 words here. The reproduction is an essential part of the life cycle of the organisms sexual reproduction is characterized by two events the union of gametes known as fertilization and meiosis this occurs in different stages of the life cycle in each type of organism In animals the embryonic stage begins with fertilization and ends with birth When fertilization heppens diploid cells are formed the juvenile stage goes from birth to sexual maturity During this stage of. Sexual maturity the procces of meiosis being to prduce gametes it is at this stage then that the reproduction of the species happens throught fertilization does not as long on the other hand males produce sperm until their death the human being goes through the stages embryonic prenatal infancy adolescence

Animal Reproduct

Animal reproduct:
The reproduction is an essential part of the life cycle of the organisms. Sexual reproduction is characterized by two events: the union of gametes, known as fertilization, and meiosis. This occurs in different stages of the life cycle in each type of organism,

Metamorphosis is a complexión process of chance that contribuye to the development of many animals
Cecle reproduction:
Egge
Pups
Tadpoles
Youth
Adult

Asexsual reproduction
• The Fragmentation.

The budding.

• Parthenogenesis. .

ANIMAL REPRODUCTION
the reproduction is an essential part of the life cycle of the organisms. sexual reproduction is charactarzed by two event the onion of gametes know as fertilization and meiosis.

In the adult stage runs from youth to death the animal cease to grow into adulthood. the female have a fertile period in which the produce eggs. but it does not last as long on the other hand male produce sperm until their death
the humans being goes through the stages embryonci prenatal infancy and adolencence, youth, adulthood and old age

metamorphosis
the metarmophosis is a complex process of change that contribute to the developement of many animal particulary in insects and amphibians it can be complete or incomplete
complete metamorphosis
happens in some fish amphibians mollusco and insect species. animal development stages are very different.
in frogs case its:

eggs
pups
tadpoles
youth
adult

and in others case can be incomplete metamorphosis
consist of severals stages: eggs, nymphs, youth and adult. this metamorphosis has not puppa stages. cockroaches and grasshopers, for example.

Diego Leonardo

Animal reproduction is when 2 animals have babies but when they are still in the pan, they are ovules that develop over time, it is the reproduction of animals but the baby when the baby needs a lot of care by his mother because he is easy prey for the other animals because he is defenseless and still needs food to survive that what I think

metamorphosis is a change that exists in some animals such as frogs 🐸 they change from being eggs to tadpoles etc. that is metamorphosis for me
