Assertion : Leaf in Opuntia functions for the storage of sugars .
Reason : Sugar is transported from leaves in Opuntia and gets stored in stem .

Options

A. If both Assertion and Reason are true and the Rea-son is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Rea-son is not the correct explanation of the Assertion.
C. If Assertion is true, but Reason is false.
D. If Assertion is false and Reason is true

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "Leaf in Opuntia functions for the storage of sugars." Opuntia, commonly known as prickly pear, is a type of cactus. In cacti, the leaves are modified into spines, and the stem performs the functions typically associated with leaves, including photosynthesis and storage.

2. **Understanding the Reason**: The reason provided states that "Sugar is transported from leaves in Opuntia and gets stored in the stem." In Opuntia, the stem is the primary organ for photosynthesis, and it synthesizes sugars. The sugars produced in the stem can be transported to other parts of the plant, including the stem itself for storage.

3. **Evaluating the Truth of the Statements**:
- The assertion is somewhat misleading. While the stem is primarily responsible for photosynthesis and sugar storage in Opuntia, the leaves (which are actually spines) do not function in sugar storage.
- The reason is accurate in stating that sugars are transported from the leaves (or more accurately, from the stem) and stored in the stem.

4. **Conclusion**:
- The assertion is not entirely correct because it implies that the leaves are responsible for sugar storage, which is not the case in Opuntia.
- The reason is correct as it accurately describes the process of sugar transport and storage.

5. **Final Answer**: Both statements are true, but the assertion is not a correct explanation of the reason. Therefore, the correct answer is that the assertion is false, but the reason is true.
