THE REASON IS THAT
the vacoule are the membranous vescicular structure in the cell of the living organisms.the vacoulee are involved in the storage of food material.the presence of vacules provides rigidity and shape to the cell with the help of turbulence.the wastes from the cells can be excreted with the help of the movement of the vacoule s. the vacoules are not responsible for locomotions.
THUS, THE CORRECT ANSWER IS OPTION D
IT HOPEFULLY HELP YOU.

The correct answer is option 'D', Locomotion.

The vacuole is a membrane-bound organelle found in plant and fungal cells. It plays several important functions, but locomotion is not one of them. Let's break down the functions of the vacuole to understand why option 'D' is the correct answer.

a) Storage:
One of the primary functions of the vacuole is storage. The vacuole can store various substances such as water, ions, sugars, pigments, and toxins. By storing these substances, the vacuole helps maintain the cell's internal balance and regulates the concentration of different molecules.

b) Providing turgidity and rigidity to the cell:
The vacuole is essential for maintaining the shape and structure of plant cells. It provides turgidity and rigidity to the cell by storing water and creating internal pressure. This is particularly important for plant cells as it allows them to maintain their shape and support the plant's overall structure.

c) Waste excretion:
The vacuole also plays a role in waste excretion. It can store and isolate toxic substances or waste products, preventing them from harming the rest of the cell. This function is particularly important for plants because they cannot actively move away from waste products or toxins, so the vacuole acts as a storage compartment for these harmful substances.

d) Locomotion:
Unlike animal cells, plant cells do not have the ability to move independently. Plant cells are generally stationary, and their movement is limited to growth and response to stimuli. Locomotion, which involves active movement from one place to another, is not a function of the vacuole in plant cells. Instead, plant cells have other structures such as cytoskeleton filaments and motor proteins that are involved in cell movement.

In conclusion, the correct answer is option 'D', locomotion. The vacuole in plant and fungal cells does not play a role in locomotion but rather functions in storage, providing turgidity and rigidity, and waste excretion.
