What would happen to a plant cell in a hypotonic solution
mash [69]
<h2>Answer:</h2>

<u>When a plant cell is placed in a hypo-tonic solution It becomes turgid and hard.</u>


<h2>Explanation:</h2>

A hypotonic solution refers to a solution that has less solute and more water than another solution. 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. The pressure inside the cell rises until this internal pressure is equal to the pressure outside.
