differentiate between internal fertilization and external fertilization class 8 ncert

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 external Fertilisation 8th?

Type of fertilisation in which the fusion of male gamete and a female gamete takes place outside its body is called external fertilisation. Though the animals like frog and fish which undergo external fertilisation, lay hundreds of eggs , all the eggs do not get fertilised and hence do not develop into new frogs.

How do internal fertilization and external fertilization differ Brainly?

Answer. Answer: Internal fertilization is the process of fusion of sperm with an egg inside the female body whereas external fertilization is the process of fusion of sperm with the egg outside the body.

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 are the similarities 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 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.

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 internal and external fertilization in animals?

The process of the internal fertilization takes place inside the female body, and the offspring develops there only, while in external fertilization this process happens outside the body that is in the external aquatic environment. ... There are no such types of external fertilization.

What are the two types of Fertilisation?

Animals also produce gametes for fusion. But the fusion of gametes may take place inside or outside the body. Based on this, fertilization is of two types – internal and external fertilization.

What is cloning for Class 8?

Cloning is the production of an exact copy of an animal by means of asexual reproduction. ... The nucleus of a normal body cell of the animal is transferred into an empty egg cell . The newly formed egg cell is allowed to develop normally.An exact copy of the animal is produced. Ewe is a female sheep.

What are advantages 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.
