Can external Fertilisation occur on land?

Fertilisation cannot be external in land animals.

Where is external fertilization most common?

Among vertebrates, external fertilization is most common in amphibians and fish. Invertebrates utilizing external fertilization are mostly benthic, sessile, or both, including animals such as coral, sea anemones, and tube-dwelling polychaetes. Benthic marine plants also use external fertilization to reproduce.

Can external fertilization occur both in water and on land?

External fertilisation can occur both in water and on land. 2. The eggs of fish are covered by hard shells for protection.

Why does external fertilization generally occur in aquatic environment?

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.

How does internal fertilization facilitate life on land?

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.

Where does internal fertilization occur?

Internal Fertilization in Humans

The male introduces the sperms into the female reproductive tract. The sperm fuses with the egg in the ampulla of the fallopian tube. This results in the formation of a zygote which undergoes mitosis to form an embryo. The embryo is then implanted into the uterus.

Which of the following shows external Fertilisation?

Answer: Fish. Salmon, cod, trout, and char are all examples of the fish that externally fertilize. The female and male both release their gametes into the water, where they diffuse together and fertilize.

Where in the human body does an egg get fertilized Class 8?

(a) In the human body does the egg (ovum) get fertilized in the fallopian tube.

What kind of fertilisation takes place in hen?

Internal fertilisation take place in hen also. 1)After fertilisation takes place inside the body of the hen, the fertilised egg or zygote divides repeatedly to form embryo which travel down the oviduct.

Is fish internal or external fertilization?

Most fish species spawn eggs that are fertilized externally, typically with the male inseminating the eggs after the female lays them.

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.

Do Frogs do external fertilization?

In most species of frogs, fertilization is external. The male frog grabs the female's back and fertilizes the eggs as the female frog releases them (Figure 2.2B).

Why do you think external fertilization occurs generally in aquatic animals not terrestrial animals?

External fertilisation of the female gamete by the male gamete takes place mostly in water; because water facilitates: extended period of gamete survival and easy movement of sperms towards egg.

Does internal fertilization occur in birds?

Birds. Most birds do not have penises, but achieve internal fertilization via cloacal contact (or “cloaca kiss”). In these birds, males and females contact their cloacas together, typically briefly, and transfer sperm to the female.

Do chickens have internal or external fertilization?

Chickens — like other birds — lay fertilized eggs via sexual reproduction.

How does internal fertilization facilitate life on land quizlet?

How does internal fertilization facilitate life on land? Internal fertilization allows the sperm to reach the egg without either gamete drying out.

What is the difference between internal & external 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.

Why is internal fertilization essential for true terrestrial living?

Why is internal fertilization essential for true terrestrial living? Internal fertilization continues the life cycle on land rather than in water. No need for water to aid in fertilization.
