Question

Plants and animals that live in estuaries face a dilemma in maintaining water balance inside their cells. During high tide they are in salt water, while at low tide they are in fresh water. During low tide a plant cell will have an advantage over an animal cell because of its ____.
a. an isotonic solutionb. a hypertonic solutionc. a hypotonic solutiond. osmosise. equilibrium

Answer 1

Answer:

The correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.

Explanation:

The plant cell has a rigid cell wall that provides support to the plant cell that is not the case in the animals as they lack the cell wall. The low tidewater is an example of the hypotonic solution as it has fewer solutes than the plant cells or animal cells.

When a plant cell is in freshwater it takes up the water with the help of osmosis and begins to swell but the cell wall does not let it burst and become turgid.

Thus, the correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.
