Verified Answer
Direction: In the following questions, a statement of assertion (A) is...
Meristematic tissues, after differentiation, give rise to permanent tissues. These constitute the major portion of the plant body.
1 A plant is composed of two main types of tissue: meristematic tissue and permanent tissue. Meristematic tissue consists of actively dividing cells found in root and shoot tips. As growth occurs, meristematic tissue differentiates into permanent tissue, which is categorized as either simple or complex.
2 Meristematic tissue cells are either undifferentiated or incompletely differentiated, and they continue to divide and contribute to the growth of the plant. ... Such cells take on specific roles and lose their ability to divide further. They differentiate into three main types: dermal, vascular, and ground tissue.

Direction: In the following questions, a statement of assertion (A) is...
Assertion: Meristematic tissues constitute the major portion of the plant body.
Reason: Meristematic tissues consist of differentiated cells.
The correct answer is option 'D' - Assertion (A) is false but reason (R) is true.
Explanation:
Meristematic tissues are undifferentiated cells that have the ability to divide and give rise to various specialized cells of the plant. They are responsible for the growth and development of the plant.
1. Meristematic Tissues:
- Meristematic tissues are found in the growing regions of the plants, such as the tips of roots and shoots, and the cambium layer.
- These tissues are composed of actively dividing cells, which can differentiate into various types of cells.
- Meristematic tissues are responsible for primary and secondary growth in plants.
2. Differentiated Cells:
- Differentiated cells are specialized cells that have undergone changes in structure and function to perform specific tasks.
- These cells have acquired specific characteristics to perform specific functions in the plant body.
- Differentiated cells are found in various plant tissues, such as parenchyma, collenchyma, sclerenchyma, and xylem and phloem.
3. Analysis of the Assertion and Reason:
- The assertion states that meristematic tissues constitute the major portion of the plant body, which is not true. Meristematic tissues are present in specific regions of the plant and do not form the majority of the plant body.
- The reason states that meristematic tissues consist of differentiated cells, which is true. Meristematic tissues contain undifferentiated cells that have the potential to differentiate into various specialized cells.
4. Conclusion:
Based on the above analysis, we can conclude that the assertion is false as meristematic tissues do not constitute the major portion of the plant body. However, the reason is true as meristematic tissues consist of undifferentiated cells that have the potential to differentiate into specialized cells.
Reason: Meristematic tissues consist of differentiated cells.
The correct answer is option 'D' - Assertion (A) is false but reason (R) is true.
