When the plant cell is placed in a hypotonic solution, it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become “turgid” i.e. swollen and hard. So it is because of endosmosis that cell becomes turgid.

Correct Option: C

Although beaks vary significantly in size and shape from species to species, their underlying structures have a similar pattern. All beaks are composed of two jaws, generally known as the upper mandible (or maxilla) and lower mandible (or mandible).

Wilhelm Roux is credited with the establishment of the basic principle of tissue culture in 1885. However, it was Gottlieb Haberlandt, an Austrian botanist, who first pointed out the possibilities of the culture of isolated tissues, plant tissue culture.

These types of movements have been termed seismonastic movements. The movement occurs when specific regions of cells lose turgor pressure, which is the force that is applied onto the cell wall by water within the cell vacuoles and other cell contents.
