Questions Related to oviparous and viviparous
Microlecithal eggs are found in
-
Reptilia and Aves
-
Amphibia, Aves and Reptilia
-
Reptilia, Aves and Chiroptera
-
Eutheria
Yolk is composed of
-
Carbohydrate
-
Protein
-
Phospholipid
-
All of the above
The yolk is a part of an egg, that feeds the developing embryo in animals. It is composed of carbohydrates (3.5%), protein (16%) and fats (phospholipids 26.5%) of total yolk. The main fatty acids present in the yolk is oleic acid, linoleic acid, palmitic acid etc.
Yolk is synthesized in
-
Liver
-
Fat bodies
-
Both A and B
-
Sertoli cells
The process of formation of the yolk is known as vitellogenesis. These are generally used to nourish the developing embryo in oviparous animals. They are deposited during oocyte maturation for use after fertilization and are synthesized in the liver or fat bodies as a common precursor termed vitellogenin.
Yolk cytoplasm contains
-
Ooplasm
-
Protoplasm
-
Deutoplasm
-
Trophoplasm
- Deutoplasm is the nutritive material present in the egg for development and nourishment of embryo. It is a non-living portion of the egg.
- Deutoplam is present in the yolk of eggs. Sometimes yolk and deutoplasm are used synonymously.
Animals which give birth to young ones are called as
-
Amphibious
-
Oviparous
-
Triploblastic
-
Viviparous
Amphibious are the animals that can live on water as well as on land.
Oviparous are the animals that lay eggs.
Triploblastic describes the animal having a body composed of three embryonic cell layers as the ectoderm, mesoderm, and endoderm.
Viviparous are animals that give birth to live young one that has developed inside the body of the parent.
Egg-producing animals such as birds are called as
-
Unisexual
-
Oviparous
-
Viviparous
-
Hermaphrodite
Unisexual is where the organism is either male or female.
Oviparous animals are those that lay eggs, with little or no other embryonic development within the mother.
Viviparous are animals that give birth to live young ones.
Hermaphrodite is the one which has both male and female reproductive organs.
So, the correct answer is option B.
Which of the following animals are correctly categorised ?
Oviparous | Viviparous |
---|---|
A. Human,cow | Snake, Pigeon |
B. Hen, Snake | Human, Crocodile |
C. Pigeon, Crocodile | Rat, Horse |
D. Toad, Earthworm | Cockroach, Cat |
-
A
-
B
-
C
-
D
Oviparous are the animals that lay eggs and the embryonic development majorly takes place outside the body of the mother. From the options, pigeon and crocodile lay eggs.
Viviparous are the animals that give birth to live young ones that have developed inside the body of the female parent, Of the given options, rat and horse are viviparous.
So, the correct answer is option C.
Egg laying animals are known as
-
Viviparous
-
Oviparous
-
Sterile
-
Hermaphrodite
Oviparous animals lay an egg and the embryonic development takes place outside the human body. Example birds.
While viviparous animals are those that give birth to live young ones. Example human beings.
So, the correct answer is option B.
The development of embryo inside an egg is called as
-
Vivipary
-
Carnivorous
-
Omnivorous
-
Ovipary
Vivipary is the development of the embryo inside the body of the mother, eventually leading to live birth.
Carnivorous are animals that feed on animal tissues.
Omnivorous are animals that feed on plant and animals.
Ovipary is the method of reproduction in which eggs are laid and embryos develop outside the mother's body, each egg eventually hatching into a young animal.
So, the correct answer is option D.
The animal that reproduces by laying eggs is
-
Cat
-
Dog
-
Cow
-
Fish
Fish lay eggs instead of giving birth to little fish. As the fish grow, they hatch into fry with an attached yolk sac and then mature into fish. The process usually takes around a week to 10 days, although it can vary widely. Cat, dog, and cow can not lay eggs.
