Assertion: Plant cells have very large vacuoles.
Reason: In plant cells, vacuoles are full of cell sap.

The correct answer is option 'A': Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

Explanation:
Plant Cell Vacuoles:
- Vacuoles are membrane-bound organelles found in the cells of plants, fungi, and some protists.
- Plant cells typically have one or more large vacuoles filling much of their interior.
- Vacuoles in plant cells are larger than those found in animal cells.

Function of Vacuoles in Plant Cells:
- Plant cell vacuoles have various functions.
- They help maintain the shape and structure of the cell by providing turgor pressure.
- Vacuoles also store water, ions, sugars, pigments, and other substances.
- They play a role in osmoregulation, maintaining the balance of water and solutes within the cell.
- Vacuoles can also contain enzymes involved in the breakdown of macromolecules.

Cell Sap:
- Cell sap is the fluid found inside vacuoles in plant cells.
- It is a solution of water, sugars, salts, pigments, and other substances.
- Cell sap provides a medium for storing and transporting nutrients and waste products within the cell.
- The composition of cell sap can vary depending on the specific needs of the plant.

Relationship between Assertion and Reason:
- The assertion states that plant cells have very large vacuoles, which is true.
- The reason explains that vacuoles in plant cells are full of cell sap, which is also true.
- The reason provides a correct explanation for the assertion because the presence of a large vacuole filled with cell sap is a characteristic feature of plant cells.

Conclusion:
- Both the assertion and the reason are true.
- The reason correctly explains why plant cells have very large vacuoles.
- Therefore, option 'A' is the correct answer.
