Assertion: Vascular or conductive tissue is a distinctive feature of complex plants.
Reason: Vascular tissue has made survival of complex plants possible in terrestrial environment.
Explanation:
The given statement consists of an assertion and a reason. Let's analyze each part separately:
Assertion: Vascular or conductive tissue is a distinctive feature of complex plants.
Vascular tissue, which includes xylem and phloem, is indeed a distinctive feature of complex plants. It is responsible for the transport of water, minerals, and food throughout the plant. This tissue forms a network of tubes that extends from the roots to the leaves, stems, and other parts of the plant. Vascular tissue allows plants to efficiently distribute nutrients and water, enabling their growth and survival.
Reason: Vascular tissue has made survival of complex plants possible in the terrestrial environment.
The reason provided is also correct. Vascular tissue has played a crucial role in the adaptation of complex plants to terrestrial environments. By having specialized conductive tissue, plants are able to absorb water and nutrients from the soil through their roots and transport them to other parts of the plant. This allows plants to grow taller, develop extensive root systems, and explore new habitats. Vascular tissue also helps in the transport of sugars and other organic compounds produced during photosynthesis from the leaves to other parts of the plant. Without vascular tissue, the survival of complex plants in the terrestrial environment would be challenging.
Conclusion:
Both the assertion and reason are true. The reason provided correctly explains why vascular tissue is a distinctive feature of complex plants. Therefore, the correct answer is option 'B' - Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
