Problem 114 - Objective Biology for NEET

Question

Assertion: Cockroach is monoecious. Reason: Male and female sex organ is present in single organism.

Step-by-Step Solution

Answer

Both the assertion and reason are correct and the reason is the correct explanation of the assertion.

Step 1: Understand the Assertion and Reason

The assertion posits that the 'Cockroach is monoecious', meaning a single organism possesses both male and female reproductive organs. The reasoning provided is that 'Male and female sex organ is present in single organism.' Essentially, we are being asked to check if the assertion is accurate, and if the reason provided correctly explains it or not.

Step 2: Validate the Assertion

Research reveals that the assertion is correct. Cockroaches are indeed monoecious (hermaphrodites), meaning they hold both the male and female reproductive structure within a single organism.

Step 3: Validate the Reason

The reason mentioned is also correct, providing a correct explanation of monoecious organisms. The presence of both male and female sex organs within a single organism indeed classifies it as monoecious.

Step 4: Conclude the Analysis

Both the assertion and reason are correct, and the reason accurately explains the assertion. Therefore, the final answer should indicate this.

Key Concepts

Biology NEET Preparation

Studying for the National Eligibility cum Entrance Test (NEET) requires a clear understanding of various biology concepts, one of which includes the reproductive system of different organisms.

From the perspective of competitive exams like NEET, the detail on reproductive systems spans across a myriad of species, ranging from plants to animals. For instance, understanding that a cockroach is monoecious plays a role when answering taxonomy and anatomy questions.

To prepare effectively for these types of questions, students should focus on memorizing the classification of organisms based on their reproductive structures and should be ready to apply this knowledge in both direct question formats and more complex scenario-based problems.

Reproductive System

The reproductive system is a biological system comprised of organs used in sexual reproduction. Various species exhibit different reproductive strategies, and the monoecious system seen in cockroaches is just one example.

A monoecious organism, also known as a hermaphrodite, possesses both male and female reproductive structures. In the context of the cockroach, their reproductive system is incredibly complex, with males having testes and females having ovaries within one individual.

In addition to recognizing such structural aspects during NEET preparation, students should also be familiar with the underlying functional aspects, such as how fertilization occurs in monoecious organisms and how their reproductive systems contribute to their survival and propagation.

Assertion Reason Questions

Assertion Reason questions are a common format in competitive exams like NEET, where students must analyze two statements: an 'assertion' which is a claim, and a 'reason' which is supposed to provide the rationale behind the claim.

When facing such questions, it is essential to first understand both statements individually, and then evaluate whether the reason logically supports the assertion. Students should practice these types of questions to familiarize themselves with the logic and reasoning required, which is invaluable for solving complex problems.

Example:

• Assertion: Cockroach is monoecious.
• Reason: Male and female sex organs are present in a single organism.

In this example, both the assertion and reason are correct, and more importantly, the reason supports the assertion correctly, indicating a deep understanding of the concept.
