Marine protozoans transferred to river water will

• A. Immediately die
• B. Get enlarged in size
• C. Shrink
• D. Not change

Answer 1

The correct option is B Get enlarged in size

If marine protozoans are transferred to river water, there will be development of vacuoles in the cell sap inside each cell, due to infiltration of low osmotic water towards high concentrated animal cells. Initially, the animal will swell and then due to turgor pressure and salt exchange, it will make equilibrium with surrounding water concentration and will come in original shape.
