Question

What will the result be if a cell contains a higher concentration of water than the surrounding medium?
A. Exosmosis
B. Plasmolysis
C. Diffusion
D. Facilitated diffusion

Answer 1

Hint: In general, a plant or animal cell will swell, when it is placed in a hypotonic arrangement. However, the plant or animal cell will shrivel when it is placed in a hypotonic structure. According to the scientific theory, a solution outside of a section is called hypotonic if it has a lower grouping of solutes comparative with the cytosol. On the other hand, If a cell is set in a hypertonic arrangement, water will leave the section, and the cell will contract.

Complete answer:
At the point when a cell is put in a hypertonic arrangement, the water moves out of the cell, and the cell gets flaccid. This development of water out of the cell is known as exosmosis. This happens because the solute centralization of the surrounding solution is higher than that inside the cytoplasm.
At the point when a cell has higher water fixation than the surrounding medium, then exosmosis happens because of the distinction in water focus in the cell and encompassing medium, which causes the cell to shrink. During this cycle, the dissolvable moves out of the phone and assimilation occur outside the separate cell.
Examples of exosmosis:
-When grapes are kept in the highly concentrated sugar emulsion, they become flaccid.
-Section of water from root hair cells to cortical cells of the root.
-Movement of water out from the raisins when put in a hypertonic arrangement.

Hence, the correct answer is option (A).

Additional information: Plasmolysis is the cycle wherein cells lose water in a hypertonic arrangement. The converse cycle, de-plasmolysis or cytolysis, can happen if the cell is in a hypotonic arrangement bringing about a lower outer osmotic weight and a net progression of water into the cell.
Diffusion is the advancement of a substance from a zone of high obsession to a region of low fixation. Distribution occurs in fluids and gases because their particles move haphazardly all around.
Facilitated diffusion is the cycle of an unconstrained latent vehicle of particles over an organic membrane through explicit transmembrane vital proteins.

Note: At the point when the arrangement encompassing the cell is hypertonic, exosmosis happens, and the space between the cell wall and cytoplasm is loaded up with solutes, as the vast majority of the water depletes away and subsequently the fixation inside the cell turns out to be more hypertonic. Exosmosis is the section of a liquid through a semipermeable membrane toward an answer of lower focus, particularly the entry of water through a cell layer into the encompassing medium.
