A normal plant cell holds water in the vacuole of the cell. This large organelle also gives the cell support. Suppose a plant is submerged in salt water. As a result

The plant will wilt

Explanation:

When a plant is submerged in salt water whose salt concentration is hypertonic to the cell sap present in the vacuole, the vacuole lose water to the surrounding solution through osmosis.

Consequently, within a short period, the cells of the plant wilt due to the flaccidity of the vacuole as a result of water loss to the surrounding.

bacterium is not correct

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
