Which is common between internal and external fertilization?
The similarity between internal fertilization and external fertilization is that the sperm fuses with the egg cell to form a zygote. The dissimilarity is that in internal fertilization, the fusion occurs inside the body of the organism while in external fertilization, the fusion occurs outside the body of the organism.
What is fertilization difference between external fertilization and internal fertilization?
Difference Between Internal and External Fertilization
| Internal Fertilization | External Fertilization |
|---|---|
| Only male gametes are discharged into the female genital tract | Both female and male gametes are discharged into the external surroundings |
| Site of further development | |
| Inside the female body | Outside the body |

What is internal fertilization and external development?
Internal fertilization occurs most often in land-based animals, although some aquatic animals also use this method. In oviparity, fertilized eggs are laid outside the female’s body and develop there, receiving nourishment from the yolk that is a part of the egg.
Where does external fertilization occur?
External fertilization in animals usually occurs in water or in damp areas in a process called spawning. Moisture in the environment keeps the gametes from drying out. Moisture is also important so the eggs and sperm can move around freely, which lets them meet and fuse.
What is the difference between fertilisation and fertilization?
As nouns the difference between fertilisation and fertilization. is that fertilisation is (chiefly|british) alternative spelling of fertilization while fertilization is the act or process of rendering fertile.
What is internal fertilization explain with 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 meant by internal Fertilisation?
Internal fertilization is the union of an egg and sperm cell during sexual reproduction inside the female body. Following fertilization, the embryos are laid as eggs in oviparous organisms, or continue to develop inside the reproductive tract of the mother to be born later as live young in viviparous organisms.
What are examples of external fertilization?
Mention Some External Fertilization Examples. Aquatic animals generally release their gametes directly into the environment.
What are the disadvantages of external fertilization?
Disadvantages of External Fertilization A large number of gametes are left unfertilized and wasted. Predators and other environmental hazards reduce the chances of fertilization. The sperm might not necessarily come in contact with the eggs. The gametes or the zygote dessicate.
What is meant by external fertilization?
External fertilization is a mode of reproduction in which a male organism’s sperm fertilizes a female organism’s egg outside of the female’s body. It is contrasted with internal fertilization, in which sperm are introduced via insemination and then combine with an egg inside the body of a female organism.
What are the similarities of internal external fertilization?
Similarities Between Internal and External Fertilization Both internal and external fertilization are mechanisms of fusing female gametes with male gametes. Both internal and external fertilization occurs in animals as well as plants. Mobile sperms and immobile egg cells are produced in both
