Question

A tadpole is the young one of a frog.
a. True
b. False

Answer 1

Hint: Frog belongs to the Animalia Kingdom, class Amphibia. Tadpole is a larval stage in an amphibian life cycle. Tadpoles of frogs are globular with internal gills, and laterally compressed tail. The size of the tadpoles varies among species and developmental stages. Tadpoles are used as food. The life cycle involves a larval stage that is intermediate between embryo and adult. They breathe through gills in water.

Complete answer:
- A tadpole is the young one of a frog which mainly survives in water.
- Frogs have gills for breathing.
- Dissolved oxygen is absorbed by them through the skin.
- They can survive both on water and land and have lungs to breathe.
- The frog lacks ribs and a diaphragm. These in humans serve in expanding the chest and thereby decreasing the pressure in the lungs allowing outside air to move in.

Hence, the correct answer is option (A).

Additional information:
- Tadpoles of frogs are herbivorous whereas tadpoles of caecilians and salamanders are carnivorous.
- Some tadpoles are obtained for medicine and food.
- Most tadpoles are aquatic whereas some species are terrestrial.
- Gills, tails and lateral lines are not found in adult amphibians.
- Tadpoles use rainwater or pond water and do not use tap water.

Note: A tadpole is the immature form of frogs or the aquatic larva of frogs after the internal gills develop and before the resorption of the tail and the appearance of the forelimbs. The tadpole stage stays from one to three months. Once the eggs are hatched, it takes 14 weeks for the tadpole to become a tiny frog. The process of transformation of a tadpole into a frog is known as metamorphosis. Tadpoles do not use tap water because chlorine present in tap water is toxic to tadpoles. Tadpoles can eat each other, feed on tadpole meat.
