Question

If too much water is lost from the plant cells during osmosis, what will happen to the cell?
A. It shrinks
B. It expands
C. Size doubles up
D. None of the above

Answer 1

Hint: The osmotic pressure along the medium involved in the process is referred to as osmosis. It's also one of the answers in action's colligative properties.
Osmosis is a process in which the solvent from a low concentrated solution travels through a semipermeable membrane to a high concentrated solution until the solution finds equilibrium. It is a passive and spontaneous process that takes place without the use of any energy. It simply entails the flow of molecules from one region to the next until equilibrium is reached.

Complete answer:
Option A: Outside the cell membrane, plant cells contain a strong stiff cell wall. This prevents the cell from bursting as it absorbs water by osmosis. The cell becomes hard as the pressure rises. Plant cells that lose too much water by osmosis become less stiff, and the cell membrane finally shrinks away from the cell wall.
So option A is correct.
Option B: When a plant cell loses too much water, the contents of the cell decrease. The cell membrane is pulled away from the cell wall as a result of this. A cell that has been plasmolyzed is unlikely to survive.
So option B is not correct.
Option C: The contents of the cell - the cytoplasm and vacuole - push against the cell wall in pure water, causing the cell to become turgid. Non-woody plants' stems are supported by fully turgid cells. The cell contents lose water through osmosis in a highly concentrated solution (low water potential). They contract and separate from the cell wall.
So option C is not correct.
Option D: When you put an animal or plant cell in a hypertonic solution, it loses water and shrinks ( water moves from a higher concentration inside the cell to a lower concentration outside ).
So option D is not correct.

So option A is the correct answer.

Note:
Any solvent, including gases and supercritical liquids, can go through the osmosis process.
The external pressure that causes the zero-net transport of solvent across the membrane is known as osmotic pressure. In a nutshell, it's just a little extra pressure to prevent osmosis.
The phenomena of osmosis can be seen in a variety of situations. Red blood cells (RBCs) and Plants' roots.
Semi-permeable membrane- A semi-permeable membrane is a thin membrane that allows some molecules (usually tiny) to flow through but not others.
