What is the SIMILAR between external fertilization and internal fertilization?

Similarities Between Internal and External Fertilization Both internal and external fertilization occurs in animals as well as plants. Mobile sperms and immobile egg cells are produced in both internal and external fertilization. The final result of both internal and external fertilization is the zygote.

What is the similarities of internal and external fertilization?

What are the Similarities Between External and Internal Fertilization? External and internal fertilization are two types of fertilization occur in sexual reproduction. In both types, a male and a female gamete fuse with each other. Also, both results a diploid zygote.

What is common and external fertilization?

External fertilization usually occurs in aquatic environments where both eggs and sperm are released into the water. ... Most external fertilization happens during the process of spawning where one or several females release their eggs and the male(s) release sperm in the same area, at the same time.

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 external fertilization Why is it disadvantageous compared to internal fertilization?

Internal fertilisation occur in organisms like human and external fertilisation occur in organisms like frogs. Disadvantage if external fertilisation is that there is less chances of meeting of sperm and ova whereas in internal fertilisation there is more chances if fertilisation.

What is the difference between internal and external fertilization?

Q9) Differentiate between internal fertilisation and external fertilisation. 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.

What is the difference between zygote and Foetus?

Zygote is a fertilized egg formed after the fusion of the sperm with the egg. It divides several times to form an embryo. On the other hand, Foetus is a stage of the embryo that shows all the main recognizable body parts of a mature organism.

What is meant by the terms internal fertilization and external fertilization explain with examples?

Internal fertilisation is in which fusion of male and female gametes take place inside female. body. example---fertilisation that occur in humans,fertilisation occurs in birds,etc. External fertilisation is in which fusion take place outside female body. example---fertilisation occur in frogs,etc.

What is the meaning of internal fertilization?

Internal fertilization is characterized by sperm fertilizing the egg within the female; the three methods include: oviparity (egg laid outside female body), ovoviparity (egg held within female), and viviparity (development within female followed by live birth).

Is Dog internal or external fertilization?

When we think about organisms mating, often we think of animals around us—humans, dogs, dragonflies, cats, lizards, or maybe birds. When these animals mate with each other, the egg and sperm meet inside the body, not outside in the air or water.

Which fertilization is more advanced external fertilization or internal fertilization give reasons?

External fertilization is primitve and internal fertilization is advance. External fertilization is not advanced because it occurs outside the body of the organisms, mostly in water in most aquatic organisms so that a large number of gametes are wasted.

What is external fertilization class 12 biology?

External fertilization is the process in which the fusion of male and female gamete takes place outside the female body in an external medium, generally water. For example, fish, frog, starfish etc.

What is the external fertilization give example?

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.

Why is external fertilization advantageous?

Advantages of External Fertilization

It results in increased genetic variations. It produces a larger number of offsprings. The gametes released can drift and therefore it is easy to find mates.

How does the external fertilization in fish occur quizlet?

How does the external fertilization in fish occur? Eggs and sperm are deposited in the same area, usually in a protected place such as floating plants or other shallow, gravel areas. Define the term.
