Assertion and Reason Analysis:
Assertion: Apical and intercalary meristems contribute to the growth in length, while the lateral meristems cause an increase in girth in maize.
Reason: Apical and intercalary meristems always increase the height of plants.
Explanation:
- Apical and Intercalary Meristems: Apical meristems are located at the tips of roots and shoots, while intercalary meristems are found at the base of leaves and internodes. These meristems are responsible for primary growth in plants, contributing to the increase in length by adding new cells to the tips of roots and shoots.
- Lateral Meristems: Lateral meristems, such as vascular cambium and cork cambium, are responsible for secondary growth in plants. They contribute to the increase in girth or thickness of plant stems and roots by adding new cells to the lateral sides.
- In the case of maize: In maize plants, apical and intercalary meristems primarily contribute to the growth in length, allowing the plant to increase in height. On the other hand, lateral meristems are responsible for the increase in girth, leading to the thickening of the stems and roots.
- Assertion and Reason Evaluation: The assertion is true as different types of meristems have specific roles in plant growth. However, the reason provided is not entirely accurate as apical and intercalary meristems do not always increase the height of plants, but they do contribute significantly to length growth.
Therefore, the correct answer is option 'D' - Both Assertion and Reason are false.
