Understanding Muscular Tissue
Muscular tissue plays a crucial role in the movement of the body. Let's break down the Assertion and Reason to understand why option 'A' is correct.
Assertion (A): Muscular tissue consists of elongated cells responsible for movement in our body.
- Muscular tissue is indeed made up of elongated cells known as muscle fibers.
- These fibers are specialized for contraction and enable various movements, from voluntary actions like walking to involuntary actions like heartbeats.
Reason (R): Muscles contain special proteins called contractile proteins, which contract and relax to cause movement.
- The primary contractile proteins in muscles are actin and myosin.
- When these proteins interact, they enable the muscle fibers to contract, leading to movement.
- This mechanism is fundamental for all types of muscle contractions, whether in skeletal, cardiac, or smooth muscles.
Conclusion: Why Option 'A' is Correct
- Both the Assertion and Reason are true statements.
- The Reason provides a clear explanation for the Assertion: the presence of contractile proteins is what allows muscular tissue to function in movement.
In summary, muscular tissue's structure and the presence of contractile proteins work together to facilitate movement in the body, validating that both statements are true and that the Reason accurately explains the Assertion.

  • Assertion Correctness: The assertion is true. Muscular tissue indeed consists of elongated cells responsible for movement in our body.
  • Reason Correctness: The reason is also correct. Muscles do contain special proteins called contractile proteins which contract and relax to cause movement.
  • Explanation: The reason provided logically explains why muscular tissue is responsible for movement. The contractile proteins within muscles enable them to contract and relax, leading to movement. Thus, the reason is the correct explanation of the assertion.
