One of the two morphological forms of a mitochondrion is 'condensed' form observed in mitochondria with high respiratory rates (ATP formation is high with increased rates of Kreb's cycle, ETS, and oxidative phosphorylation). In this type of confirmation, the matrix volume inside inner membrane is not very large causing the inner membrane to move away from outer membrane causing the intermembrane space to swell except at the site of where two are connected. Thus considering all the details about this form of the mitochondrion.

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.

Vacuoles are the membrane-bound storage bubbles found in cells. They are large and centrally located in plant cell whereas in animal cells either they are too small or absent .They can store food materials, waste products, water etc.

• A telocentric chromosome, the centromere is located at the terminal end of the chromosome. 
• A telocentric chromosome has therefore only one arm.
• Telomeres may extend from both ends of the chromosome, their shape is similar to letter I during anaphase. 
• Hence, In the chromosome in which the centromere is located at the terminal end of the chromosome is Telocentric.
• So, the correct answer is 'Telocentric'.
