Question

Chapter 37, Problem 1SA

Summary Introduction

Introduction:

Waste materials present in the body (as a result of metabolism) need to be excreted as their accumulation may be toxic to the organism. Different organisms have different mechanisms for excretion.

Expert Solution & Answer

Answer to Problem 1SA

Correct answer:

Malpighian tubules of insects eliminate uric acid. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

Option c. is given as “insects”.

In insects, osmoregulation and excretion occur by the malpighian tubule system. It consists of a complex network of branched tubules. Wastes are absorbed from the surrounding fluid, called the hemolymph and excreted in the form of nitrogenous calcium oxalate solids.

Reason for incorrect answer:

Option a. is given as, “birds”.

Birds excrete wastes in the form of uric acid but their excretory organs are kidneys and not malpighian tubules. Hence, option a. is incorrect.

Option b. is given as, “marine fishes”.

Ammonia is the main excretory product of marine fishes. Ammonia is excreted through chloride cells in marine fishes and not in the form of uric acid from malpighian tubules. Hence, option b. is incorrect.

Option d. is given as, “earthworms”.

Ammonia is the main excretory product of annelids such as earthworms. Ammonia is excreted through nephridia and excretion in earthworms is not in the form of uric acid from malpighian tubules. Hence, option d. is incorrect.

Hence, the options a., b., and d. are incorrect.

Conclusion

In insects, uric acid is eliminated by malpighian tubules. Thus, the correct option is c.
