Difference Between External and Internal Fertilization

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 internal and external?

The difference between internal and external is that anything internal is on the inside of something, whereas anything external is on the outside of something.

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 the internal and 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.

Whats internal and external mean?

• Internal conflict, which takes place in a person's mind—for example, a struggle to. make a decision or overcome a feeling. Internal conflicts are character vs. self. • External conflict, which generally takes place between a person and someone or.

What is internal and external respiration?

External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs. Internal respiration is the exchange of gases with the internal environment, and occurs in the tissues.

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 main problem associated with external fertilization?

The main problem associated with external fertilization is its limited environment and wastage of major reproduction components.

What is the advantage of external fertilization?

External fertilization in an aquatic environment protects the eggs from drying out. Broadcast spawning can result in a greater mixture of the genes within a group, leading to higher genetic diversity and a greater chance of species survival in a hostile environment.

What are the examples of external fertilization?

Descriptive external fertilisation examples are that of salmon, trout fish and codfish. Both the female and male release their eggs and sperms respectively into the water where they diffuse and fertilize. In the list of external fertilization examples, aquatic animals such as mammals and sharks are exceptions.

What are the advantages and disadvantages of internal and external fertilization?

Advantages & Disadvantages of Internal and External Reproduction

• Increase chance gametes meet.
• 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 is internal fertilization give 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.
