Question

a farmer accidentally waters their crops with very salty water from a nearby pond. 1. cell environment: describe whether the salty water is hypertonic, hypotonic, or isotonic compared to the plant cells. 2. osmosis effect: predict the movement of water into or out of the plant cells, and explain how this will affect the shape and turgor pressure of the cells. 3. plant health: explain how this cellular effect could impact the overall health of the plant.

Explanation:

Step1: Identify solution - cell comparison

Salty water has a higher solute concentration than plant cells, so it is hypertonic.

Step2: Determine osmosis direction

In osmosis, water moves from an area of lower solute concentration (plant cells) to an area of higher solute concentration (salty water). So water will move out of the plant cells. As water moves out, the cell membrane will pull away from the cell wall (plasmolysis), reducing turgor pressure and the cell will become flaccid.

Step3: Analyze plant - health impact

Reduced turgor pressure means the plant loses its rigidity and may wilt. Also, the cells may not function properly due to water loss, which can lead to stunted growth, reduced photosynthesis, and eventually plant death if the condition persists.

Answer:

1. The salty water is hypertonic compared to the plant cells.
2. Water will move out of the plant cells. The cell will become flaccid as the cell membrane pulls away from the cell wall (plasmolysis) and turgor pressure decreases.
3. The overall health of the plant will be negatively impacted. The plant may wilt due to reduced turgor pressure, have stunted growth, reduced photosynthesis, and may eventually die if the water - loss condition persists.
