The central vacuole in a plant cell is responsible for turgor pressure. when the vacuole loses water the cytoplasm "shrinks". when the vacuole gains water the cytoplasm seems to "puff up". one structure the plant cell keep its shape no matter how much water is in the vacuole. this is the a) cell wall. b) cytoplasm. c) cytoskeleton. d) cell membrane.

The correct answer would be A) cell wall.

In a plant cell, the cell wall is the outermost layer mainly composed of cellulose. It provides protection, support, structure et cetera to the cell.

It provides mechanical support and strength to the cell and regulates the direction of cell growth.

It helps the cell in withstanding the turgor pressure and thus, helps in preventing the bursting of a plant cell in hypotonic solutions. In addition, it also prevents the shrinkage of the cell in hypertonic solutions.

It also protects the cells from invading pathogens such as viruses.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
