Complete answer: Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies.

What is the difference between external and internal fertilization quizlet?
External fertilization is when eggs are released by a female into the environment and later fertilized with a male's sperm. Internal fertilization is when sperm are deposited in or near a female's reproductive tract and fertilization takes place within the reproductive tract.
What is fertilization state the difference between internal and external fertilization with examples?
Reproduction in Animals | Exercise
| Internal fertilization | External fertilization |
|---|---|
| Fusion of male and female gametes takes place inside the body. | Fusion of male and female gametes take place outside the body. |
| A female partner lays fertilized eggs or a fully grown young one. | The female partner lays unfertilized eggs. |
What is internal fertilization give an example?
Internal fertilization is the process of fertilization that occurs inside the body of an individual. It occurs mostly in land animals. ... Different animals have different methods of transferring the sperms. For eg., in mammals, reptiles, and some fish, this is done by copulation.
What is external fertilization explain with example?
external fertilization is a case in which fusion of male and female gametes takes place in outside environment/ medium and not in the body of the female . for example, in case of frogs , fertilization takes place in water medium . the female releases eggs in the water at the same time sperms are released too.
What is the main problem associated with external fertilization?
A water body is required to initiate external fertilization. The sperms would die on land. It is a reproductive disadvantage for most of the animals because most of the gametes die without being fertilized.
What are the advantages and disadvantages of internal and external fertilization?
Increase chance gametes meet and greater change of successful fertilisation. More protection against outside environments and predators, and therefore a higher chance of surviving until birth. More selective of their mates. Less chance of desiccation of gametes.
What type of fertilization takes place in cow?
Fertilisation which takes place inside the female body is called internal fertilisation. Internal fertilisation occurs in many animals including humans, cows, dogs and hens.
What types of organisms use external fertilization?
Many fish, amphibians, and other sexual aquatic animals use external fertilization (the exceptions are aquatic mammals, sharks, and some other special types of fish). External fertilization is beneficial because the mother does not have to physically carry the developing offspring.
What are the benefits of internal fertilization?
Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. Internal fertilization also enhances the fertilization of eggs by a specific male.
Is external fertilization asexual?
Refer back to paragraph 10 to review external fertilization. Both are forms of reproduction, but binary fission is where a single cell divides into two (sexual), and external fertilization is where egg and sperm are released into the environment and combine to create a new organism (asexual).
What is internal fertilization explain with Example Class 8?
The fertilisation which take place inside the female body is called internal fertilisation. The female animal's eggs are fertilised by sperm inside her body. ... Type of fertilisation in which the fusion of a male gamete and a female gamete occurs inside the body of the female animal is called internal fertilisation.
