FAQs on Metamorphosis in Frogs - Reproduction in Animals Video Lecture - Class 8

1. What is metamorphosis in frogs?
Ans. Metamorphosis in frogs is the process through which a frog undergoes a series of developmental changes from an aquatic larva to a terrestrial adult. It involves the transformation of a tadpole into a frog, including the development of limbs, loss of the tail, and the formation of lungs.
2. How does reproduction occur in frogs?
Ans. Reproduction in frogs involves both external fertilization and external development. The male frog releases sperm onto the eggs as the female lays them, and fertilization occurs outside the body. The fertilized eggs then develop in water, typically in the form of jelly-like masses called spawn.
3. What are the stages of metamorphosis in frogs?
Ans. The stages of metamorphosis in frogs include the egg stage, tadpole stage, and adult frog stage. The eggs hatch into tadpoles, which have gills for breathing and swim using a tail. As the tadpole grows, it develops hind legs, front legs, and lungs, eventually losing its tail and becoming a fully formed adult frog.
4. How long does metamorphosis take in frogs?
Ans. The duration of metamorphosis in frogs can vary depending on the species and environmental conditions. On average, it takes around 12 to 16 weeks for a tadpole to complete its metamorphosis and transform into an adult frog. However, some species may undergo a faster or slower metamorphosis.
5. What are the advantages of metamorphosis in frogs?
Ans. Metamorphosis in frogs provides several advantages. It allows the transition from an aquatic lifestyle to a terrestrial one, enabling frogs to explore new habitats and access different food sources. Additionally, the transformation from a tadpole to an adult frog involves the development of specialized structures like lungs and limbs, which are essential for survival on land.
