A well-developed nervous system and sense organs are present in members of the class
A. Turbellaria
B. Cestoda
C. Trematoda
D. None of these
D. None of these
D. None of these
Members of the class Turbellaria refer to flatworms, specifically the free-living flatworms, which do not have a well-developed nervous system or sense organs.
Members of the class Cestoda refer to tapeworms, which also do not have a well-developed nervous system or sense organs as adults. They rely on their host organism for food absorption.
Members of the class Trematoda refer to flukes, which have a limited nervous system and basic sense organs but not a well-developed nervous system and sense organs.
Therefore, none of the options provided have members with a well-developed nervous system and sense organs.
To determine the answer to this question, we need to understand the characteristics and features of each class mentioned.
A. Turbellaria: This class represents the free-living flatworms which include planarians. They have a simple nervous system but lack specialized sense organs.
B. Cestoda: This class represents the tapeworms. Cestodes possess a complex and specialized body structure, but they lack a well-developed nervous system and sense organs.
C. Trematoda: This class represents the flukes. Like tapeworms, flukes also lack a well-developed nervous system and sense organs.
D. None of these: This option indicates that none of the mentioned classes have a well-developed nervous system and sense organs.
Based on the information provided, the class that possesses a well-developed nervous system and sense organs would be "none of these" (option D).
