Answer: In amphibians, syngamy occurs in water outside the body of the organism (external fertilisation and external development). In reptiles, syngamy occurs inside the body of the female (internal fertilisation and external development).
Where does syngamy occur in organisms?
=> In most of the algae, aquatic fungi, Bony fishes and amphibians, syngamy occurs outside the body of the organism, in the medium of water. => In certain algae and fungi, bryophytes, pteridophytes, gymnosperms and angiosperms and most of the animals, syngamy occurs inside the body of the organism.
Where does the syngamy occur .give with an example?
Explanation: syngamy occurs within the embryo sac where pollen grains are carried by pollen tube and released into the embryo sac. These gametes enter through the fillform apparatus and reach the egg cell to complete fertilization.
Where does syngamy occur in mammals?
In reptiles and mammals, syngamy occurs within the body of the organism (internal fertilisation).
Where does bird syngamy occur?
how can the zygote development be outside the body. The development of complete foetus/baby from zygote does not take place inside the body in birds and reptiles as they lack organs, space and favourable environment for their development.
Lecture 6: Amphibian Reproduction
Where do amphibians and reptiles syngamy occur?
In amphibians, syngamy occurs in water outside the body of the organism (external fertilisation and external development). In reptiles, syngamy occurs inside the body of the female (internal fertilisation and external development).
Where does syngamy occurs in amphibians fishes and higher animals such as reptiles birds?
Where does syngamy occur? In most aquatic organisms, such as a majority of algae and fishes as well as amphibians, syngamy occurs in the external medium (water), i.e., outside the body of the organism. This type of gametic fusion is called external fertilisation.
Does syngamy occur in birds?
In birds and reptiles, the fertilisation of egg and sperm takes place inside the body to form zygote. ...
When syngamy occurs inside the body of the organism The process is called?
Reason: Syngamy occurs inside the body of organism is called internal fertilisation.
Where does syngamy occur in most algae?
Syngamy occurs outside the body of the algae in majority cases. Syngamy occurs generally in water(ie. external medium),this type of fertilisation is called external fertilisation.
What syngamy means?
: sexual reproduction by union of gametes : fertilization.
What process will occur if syngamy does not occur?
Syngamy is the process of fusion of male gamete with female gamete resulting in the formation of zygote which develops into offspring. If syngamy does not takes place, there will be no zygote formation, hence no new generation produced.
What is reproduction essential for organism?
Why is reproduction essential for organisms? Answer1. Reproduction is essential for organism because through reproduction we can reproduce our young ones who are similar to us in most of our characters. Reproduction enables us to continue the life of species even after our death.
In which of the following organisms syngamy occurs outside the body?
When fertilization occurs outside the body of the organism, this type of gametic fusion is called external fertilization or external syngamy. In majority of algae, external fertilization occurs.
Why does syngamy occur Class 12?
The process of fusion of male and female gametes to form a zygote is called fertilization or syngamy. In this type of fertilization, syngamy occurs outside the body of organism. Example- in most aquatic organisms like algae, fish, amphibians.
What would happen if syngamy does not occur Class 12?
If no syngamy occurs, there will be no zygote formation, hence no new generation produced.
In which of the following does Syngamy occur usually in external medium?
In most of Aquatic organism such as majority of algae and fishes as well as in Amphibians (frog) , syngamy occurs in the external medium such as Water i.e., outside the body of organism.
What is asexual reproduction common in?
Asexual reproduction (i.e., reproduction not involving the union of gametes), however, occurs only in the invertebrates, in which it is common, occurring in animals as highly evolved as the sea squirts, which are closely related to the vertebrates.
Which organisms both male and female gametes are motile?
Dear student, In some organisms like fungi and algae both male and female gametes are motile. The male gametes need a medium through which it can move and can reach the female gamete. In plants like algae, bryophytes and pteridophytes water serve as the medium through which gamete transfer takes place.
Do mammals have cloaca?
cloaca, (Latin: “sewer”), in vertebrates, common chamber and outlet into which the intestinal, urinary, and genital tracts open. It is present in amphibians, reptiles, birds, elasmobranch fishes (such as sharks), and monotremes. A cloaca is not present in placental mammals or in most bony fishes.
What is the importance of syngamy and meiosis?
The importance of syngamy and meiosis in the sexual life cycle of an organism : Syngamy ensures the continuity of species in a sexually reproducing organism. Meiosis is the pathway to produce haploid gametes which are involved in sexual reproduction and responsible for fertilisation to occur.
In which of the following organism hatching of eggs occur inside female body?
organisms are called as ovoviviparous. example - - shark, snake, reptiles etc.
In which of the following organisms self fertilisation is seen?
In liver fluke both cross and self-fertilization is seen as they are hermaphrodites. It shows both the sex organs and thus self-fertilization is commonly seen.
What is reproductive phase?
Reproductive Phase : As the name suggests this phase is the time when the individual organism attains reproductive maturity and is sexually active. The reproduce and give birth to offspring.
What is the reproduction of organism?
Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique. In asexual reproduction, one parent copies itself to form a genetically identical offspring.
