What are the advantages and disadvantages of viviparity?
Advantage- in this, young one develop inside body of female and so gets better nourishment,proper development and better chances of survival. Disadvantage- the maturation period is long nd the offspring produced are comparatively very less.
What is the advantage of viviparity over oviparity?
Viviparity (give birth to live young) is good because the embryo can develop inside the mother where temperatures and nutrients are stable, thus enabling the young a greater chance to survive.
What are the advantages and disadvantages of oviparity?
An advantage of oviparity is the number of eggs produced, because it is likely some of the offspring will survive. However, the offspring are at a disadvantage because they must go through a larval stage in which their location is directed by oceans currents.
Why oviparous animals are disadvantages?
Being an oviparous has it on disadvantages which is they have to protect and hide their eggs during development because the eggs produce is so fragile and also to protects those eggs from predators (Mills,2018)Viviparous animals refer to the animals that give birth to offspring.
What is an advantage of viviparity?
Egg-laying is inefficient in allowing huge losses and greatly limits the size of the newborn, although it has the advantage of causing little physiological upheaval to the mother. Viviparity, on the other hand, allows the growth of a much larger fetus, offers great protection and is highly efficient.
What are the advantages of viviparous animals?
The advantages of viviparous is reproduction system that has been considered superior with own reproductive strategies. The young one gets better nourishment and also good shelf life. They have their own system. They produce the young one instead of egg.
Does being vivipary offer any advantage to organisms?
The vivipary animals have the advantage that is fertilization takes place within the female body thus the embryonic development is safe within the mothers womb.
What is a Vivipary?
Vivipary refers to a seed that germinates into a seedling before being shed from the parent plant, e.g., Rhizophora, red mangrove.
What are the differences between viviparity and ovoviviparity?
The key difference between oviparity, ovoviviparity and viviparity is that oviparity is the trait of laying eggs, while ovoviviparity is the development of embryos inside eggs that are retained within the mother's body until they are ready to hatch, and viviparity is giving birth to young ones directly.
What is the difference between viviparity and oviparity?
The main difference between oviparous and viviparous animals is that oviparous animals do not undergo any embryonic development inside the mother whereas viviparous animals develop into a young animal inside the mother. This means oviparous animals lay eggs. These eggs develop and hatch into young individuals.
What is a vivipary?
Vivipary refers to a seed that germinates into a seedling before being shed from the parent plant, e.g., Rhizophora, red mangrove.
What is the meaning of viviparity?
viviparity, retention and growth of the fertilized egg within the maternal body until the young animal, as a larva or newborn, is capable of independent existence. The growing embryo derives continuous nourishment from the mother, usually through a placenta or similar structure.
Why are not all animals oviparous does viviparous offer any advantage to organisms?
Explanation: All animals are not oviparous this is due to the fact that these have do not exhibit the capability to lay the eggs. The vivipary animals have the advantage that is fertilization takes place within the female body thus the embryonic development is safe within the mothers womb.
What is the most advantageous for developing animals oviparity Ovoviviparity or the viviparity Why do you say so?
The young one gets better nourishment and good shelf life. They have their own system. They produce the young one instead of egg. Another advantage of ovoviviparity is that the offspring are advanced in their development when they are born live, thus the juveniles are more likely to fend for themselves in the wild.
Why is vivipary an undesirable character?
It is because the seeds cannot be stored under normal conditions for the next season. Annual plants complete their life cycle in one season, wherein seeds are produced, germinated and the mature plant hence produced, dies within the same season.
Why is vivipary good for some plants?
For this select group of plants, vivipary is part of the reproductive strategy. In vivipary, seeds lack dormancy. Rather than waiting to be dispersed before germinating, viviparous seeds germinate inside of fruits that are still attached to their parent plants.
Why is Vivipary advantageous?
Egg-laying is inefficient in allowing huge losses and greatly limits the size of the newborn, although it has the advantage of causing little physiological upheaval to the mother. Viviparity, on the other hand, allows the growth of a much larger fetus, offers great protection and is highly efficient.
What is the most advantageous for developing animals oviparity ovoviviparity or the viviparity Why do you say so?
The young one gets better nourishment and good shelf life. They have their own system. They produce the young one instead of egg. Another advantage of ovoviviparity is that the offspring are advanced in their development when they are born live, thus the juveniles are more likely to fend for themselves in the wild.

Why viviparity is of survival value?
Introduction. Viviparity was one of the most significant evolutionary adaptations of vertebrate reproduction because it allowed offspring to develop within the body of the mother removed from predation and environmental pressures.
What is the most advantageous for developing animals Oviparity Ovoviviparity or the Viviparity Why do you say so?
The young one gets better nourishment and good shelf life. They have their own system. They produce the young one instead of egg. Another advantage of ovoviviparity is that the offspring are advanced in their development when they are born live, thus the juveniles are more likely to fend for themselves in the wild.
What is the difference between oviparity and viviparity?
The main difference between oviparous and viviparous animals is that oviparous animals do not undergo any embryonic development inside the mother whereas viviparous animals develop into a young animal inside the mother. This means oviparous animals lay eggs. These eggs develop and hatch into young individuals.
Why is Vivipary undesirable for annual crop plants?
It is because the seeds cannot be stored under normal conditions for the next season. Annual plants complete their life cycle in one season, wherein seeds are produced, germinated and the mature plant hence produced, dies within the same season.
What can you do with vivipary?
You can remove the sprouted seeds and eat around them, or you can turn the situation into a learning opportunity and plant your new sprouts. They likely won't grow into an exact copy of their parent, but they will produce some kind of plant of the same species that makes fruit.
What is the advantage of viviparous organisms over oviparous organisms Class 12?
The Embryo absorbs nutrients from the mother's body during its foetal stage. Eggs are exposed to several risks and damages which reduces survival rate for Oviparous Organisms. The chances of survival are high in Viviparous Animals as Embryo stays fully protected inside the mother's womb.
What is the advantage of viviparous germination?
As the authors of the Epiphyllum study put it, vivipary is “a reproductive advantage that, in addition to allowing propagules to root and grow almost immediately, favors quick establishment whenever seedlings land on suitable substrates.”
What type of reproduction is viviparity?
Viviparity (live-bearing reproduction) and oviparity (reproduction by oviposited eggs) are two basic modes of sexual reproduction in metazoans. Viviparity implies matrotrophy with placentotrophy as its most advanced form.
Why are offspring of viviparous animals at a greater risk as compared to offspring of viviparous animals?
On the other hand, in viviparous animals, the development of the egg takes place inside the body of the female. Hence, the offspring of an egg-laying or oviparous animal is at greater risk as compared to the offspring of a viviparous animal, which gives birth to its young ones.
Why is Vivipary undesirable?
It is because the seeds cannot be stored under normal conditions for the next season. Annual plants complete their life cycle in one season, wherein seeds are produced, germinated and the mature plant hence produced, dies within the same season.
What is description of viviparity?
1 : producing living young instead of eggs from within the body in the manner of nearly all mammals, many reptiles, and a few fishes. 2 : germinating while still attached to the parent plant the viviparous seed of the mangrove.
