Examines the external structure of frogs, including body parts like limbs, skin, and sensory organs. Helps understand how these features support survival and function.
Fat bodies store energy, which is utilized during reproduction for gamete production and development.

Frog skin is moist and glandular, allowing respiration through cutaneous gas exchange.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
The thyroid gland in frogs releases hormones that regulate metamorphosis from the tadpole stage to adulthood.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
Frogs undergo external fertilization, where eggs and sperm are released into water for fertilization.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
Frogs use cutaneous respiration through their skin to exchange gases in both aquatic and terrestrial environments.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
Frogs have a body divided into a head and trunk, with no distinct neck or tail.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
Frogs use their hind limbs, not just their forelimbs, for movement, jumping, and swimming.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
Frogs undergo indirect development with a larval stage (tadpole) before transforming into an adult.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
Fertilization in frogs is external, occurring in water where the male fertilizes the eggs laid by the female.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
Frogs do not excrete solid waste through their skin; they excrete liquid nitrogenous waste through their kidneys and cloaca.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
Frogs use cutaneous respiration, where gases are exchanged through their moist skin while underwater.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
Frogs undergo external fertilization, where males release sperm over eggs laid by females in water.
