The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that the constantly dividing cells at the root apex and shoot apex show the meristematic phase of growth. - **Meristematic tissue** is a type of plant tissue that is responsible for growth. It consists of actively dividing cells that can differentiate into various types of cells. - The root apex (tip of the root) and shoot apex (tip of the shoot) are regions where this type of tissue is found, allowing for the growth of roots and shoots. ### Step 2: Analyze the Reason The reason given is that the cells of this region are rich in protoplasm and are without nuclei. - **Protoplasm** is the living part of the cell, which includes the cytoplasm and the nucleus. - Meristematic cells are characterized by having a high amount of protoplasm and a large nucleus. Thus, the statement that they are without nuclei is incorrect. ### Step 3: Determine the Truth of the Statements - The assertion is **true** because the cells at the root and shoot apex are indeed constantly dividing and represent the meristematic phase of growth. - The reason is **false** because meristematic cells do have nuclei; they are not without nuclei. ### Conclusion Based on the analysis: - The assertion is true. - The reason is false. Thus, the correct answer is that the assertion is true, but the reason is false. ### Final Answer Assertion is true, Reason is false. ---
