The correct answer is option 'C', which states that the transportation of water takes place through movement of one cell to another. Let's understand why this is the correct answer.

Movement of Water in Plants
Plants have a specialized system called the vascular system, which consists of two main types of tissues: xylem and phloem. These tissues are responsible for the transportation of water, nutrients, and other substances within the plant.

1. Xylem:
The xylem tissue is responsible for the transportation of water and minerals from the roots to the other parts of the plant. It consists of long, hollow, tube-like cells called vessels or tracheids, which are interconnected to form a continuous network.

2. Phloem:
The phloem tissue is responsible for the transportation of organic nutrients, such as sugars, from the leaves to the other parts of the plant. It consists of specialized cells called sieve tubes, which are arranged end-to-end to form a tube-like structure.

Transportation of Water in Plants
Now, let's understand how water is transported in plants:

1. Transpiration:
Water is absorbed by the roots from the soil and transported upward through the xylem vessels. This process is driven by transpiration, which is the loss of water vapor from the plant's leaves through tiny openings called stomata. As water evaporates from the leaves, it creates a negative pressure or tension, which pulls more water up from the roots.

2. Cohesion-Tension Theory:
The movement of water in the xylem vessels occurs due to the cohesion-tension theory. According to this theory, water molecules are cohesive and stick together due to hydrogen bonding. As water is pulled up through the xylem, the cohesive forces between water molecules help to maintain a continuous column of water.

3. Cell-to-Cell Movement:
Within the xylem vessels, water moves from one cell to another through pits or small openings in the cell walls. This movement occurs through a process called osmosis, which is the diffusion of water across a semi-permeable membrane.

Conclusion:
In conclusion, the transportation of water in plants primarily occurs through the movement of one cell to another within the xylem tissue. This movement is driven by transpiration and the cohesive forces between water molecules. The large spaced potato cavity filled with sugar solution mentioned in the question does not play a role in the transportation of water in plants.

This process is called Osmosis .....
