• A vacuole is a membrane-bound 9tonoplast) organelle present in cells.
  
• It forms an enclosed compartment within the cell which are filled with water, dissolved inorganic and organic molecules (enzymes)
• It stores food and variety of nutrients required by the cell to survive and also store waste products which protect the cell from getting contaminated.
• So, the correct answer is 'Water and dissolved substances'.

Vacuolar membrane is a membrane surrounding the vacuole. It is also called as tonoplast. Like, cell membrane, it is semipermeable in nature. Therefore, option B is correct. 

Beet root is coloured because of the presence of anthocyanin in vacuoles .Anthocyanin is the water soluble vacuolar pigments ,they contain red colour in roots of the caryophyllales [including cactus, beet and amaranth ]these roots are contain red in colour.But otherwise anthocyanin in chloroplast and chromoplast have roots green in colour.Carotenoid of chloroplast contain orange colour pigments and they are found in carrots
So the correct option is B

A large central vacuole of a plant cell that stores water with inorganic and organic substance like sugar, salts and some pigments are the non-living fluid. It provides turgidity and osmolarity to the cell.

The chromosomes were named according to the position of the centromeres. This is expressed in the ratio “long arm to short arm”. Here the following terms are used: metacentric (arm ratio 1.0–1.7), submetacentric (ratio 1.7–3.0), subtelocentric (ratio 3.0–7.0), acrocentric (ratio more than 7.0), and telocentric (chromosome with only one arm).

Plant cell vacuoles contain water and metabolic wastes. They are widely diverse in form, size, content and functional dynamics and a single cell may contain more than one kind of vacuole. In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth. Thus, the correct answer is option D.

• A plant cell is characterized by a single large sap vacuole. They enclose sap or water or vacuolar fluid with dissolved inorganic and organic substances. It is surrounded by a membrane called tonoplast. 
• Plant cell vacuole maintains osmotic pressure for turgidity and osmosis. They also store useful as well as waste orgastic substances. Plant vacuole along with the cell inclusions is the non-living component of the cell.

Vacuoles are the membrane-bound organelle and perform various functions according to the type of cell in which they are present. Vacuoles are filled with water containing inorganic and organic molecules including enzymes in solution, though in certain cases they may contain solids which have been engulfed. The organelle has no basic shape or size, its structure varies according to the needs of the cell. 

A plant cell is characterised by a single large sap vacuole. They enclose sap or water with dissolved inorganic and organic substances. It is surrounded by a membrane called as tonoplast. Plant cell vacuole maintains osmotic pressure for turgidity and osmosis. They also store useful as well as waste substances. Thus, the correct answer is option D.

The plant cell usually has a single large centrally located vacuole. The tonoplast is a special term for the membrane found around plant cell vacuole. Thus, the correct answer is option D.
