Answer:
The water potentials (Ψ) of the cell and its surroundings are the same.
Explanation:
When a cell is kept in hypotonic surroundings such as distilled water, the osmotic movement of water occurs towards the cell. The entry of water makes the cell swell up and it becomes turgid. Water potential is determined by solute and pressure potentials mainly. Here, the solute potential of the cell and the distilled water was different resulting in differences in their respective water potential values which in turn served as a driving force for endosmosis.
When the cell is fully turgid, the solute concentration of the cell and the surrounding distilled water become equal to each other. Under these conditions, the water potential of the cell and distilled water are the same.

A
Explanation:
Digestion begins in the mouth with the process of chewing also known as mastication. Saliva in the mouth mixes with the food. saliva contains amylose. This breaks down sugar into smaller units of dextrins and maltose.
In the small intestine, the pancreas releases pancreatic juice which breaks down dextrins into smaller units.
the cells in the small intestine helps to transport the digested nutrients to the blood stream
Undigested food goes to the large intestine and eliminated in the stool
