How Do You Spell INTERNAL FERTILISATION?

Pronunciation: [ɪntˈɜːnə͡l fˌɜːtɪla͡ɪzˈe͡ɪʃən] (IPA)

Internal fertilisation is the process by which a male organism deposits sperm inside the female organism, which then leads to fertilization. The word "internal" is pronounced /ɪnˈtɜːrn(ə)l/, while "fertilisation" is pronounced /ˌfɜː(t)əlaɪˈzeɪʃ(ə)n/. The phonetic transcription explains the spelling of the word, including the silent letter "n" in "internal" and the British spelling of "fertilisation" with the letter "s". This process is found in various animal species, including mammals, birds, and reptiles.

INTERNAL FERTILISATION Meaning and Definition

1. Internal fertilisation is a reproductive process that occurs in certain organisms, particularly in animals, where the fusion of male and female gametes takes place within the female reproductive system. It is characterized by the transfer of sperm from the male to the female, which occurs inside the body of the female organism.

   In internal fertilisation, the male usually produces sperm, while the female produces eggs. The sperm is introduced into the female's body through copulation, mating or mating rituals. The female's reproductive tract then facilitates the journey of the sperm to reach the egg, which is commonly stored and fertilized within the female's body. The fusion of the sperm and the egg forms a zygote, or a fertilized egg.

   Internal fertilisation offers a number of advantages. Firstly, it increases the chances of successful reproduction as the sperm is protected from external factors that could hinder its progress, such as predators or environmental variations. Secondly, internal fertilisation allows for the provision of nutrients and protection for the developing embryo or zygote, enhancing its chances of survival. It is common in many terrestrial and aquatic organisms, including mammals, reptiles, birds, and insects.

   Overall, internal fertilisation is an important reproductive strategy that ensures the survival and continuation of many species, providing offspring with a higher probability of success and adaptability.

Etymology of INTERNAL FERTILISATION

The term "internal fertilisation" is composed of two main parts: "internal" and "fertilisation".

The word "internal" comes from the Latin word "internus", which means "inside" or "within". It is derived from the combination of "inter" meaning "between" and "internus" meaning "inward".

The word "fertilisation" comes from the Latin word "fertilis", which means "fruitful" or "fertile". It is derived from the combination of "ferre" meaning "to bear" or "to carry" and the suffix "-ilis", indicating "capable of" or "pertaining to".

Therefore, "internal fertilisation" refers to the process of fertilisation occurring within the body of an organism, typically involving the meeting of male and female reproductive cells internally.
